Myrmecophily
Guides
Masoncus
Masoncus is a genus of dwarf spiders in the family Linyphiidae, first described by Ralph Vary Chamberlin in 1949. The genus contains four species distributed in Canada and the United States. One species, Masoncus pogonophilus, has been documented living in nests of the ant Pogonomyrmex badius, where it feeds on springtails. The genus is part of the diverse sheet-web weaving spider family.
Megastilicus
Megastilicus is a genus of myrmecophilous rove beetles (Staphylinidae: Paederinae) endemic to North America. The genus was long considered monotypic, containing only Megastilicus formicarius Casey, 1889, until the description of Megastilicus iowaensis in 2021. These beetles are specialized associates of ants, particularly Formica ulkei. The genus is classified in the subtribe Stilicina based on morphological characteristics.
Metriini
Ant nest beetles
Metriini is a small tribe of ground beetles in the subfamily Paussinae, commonly known as ant nest beetles. The tribe contains at least three genera and approximately six described species. Members are found in North America and China, with one extinct genus known from Burmese amber. These beetles are associated with ant colonies, though specific ecological details remain limited.
Microdontinae
Ant Flies and Allies
A subfamily of hoverflies (Syrphidae) comprising approximately 400 species, distinguished by their obligate myrmecophilous lifestyle. Larvae develop within ant nests as predators or scavengers of ant brood, exhibiting reduced body segmentation compared to other syrphid larvae. Adults of many species remain near host ant colonies rather than visiting flowers; some species lack functional mouthparts entirely. Several genera lack the spurious vein characteristic of other Syrphidae.
Milichiella
freeloader flies
Milichiella is a genus of small flies in the family Milichiidae, commonly known as freeloader flies. The genus is cosmopolitan in distribution with numerous species described from tropical and subtropical regions. Species within this genus are kleptoparasites, attracted to predatory events where they feed on fluids from prey captured by other arthropods such as spiders and assassin bugs. The genus has undergone significant taxonomic revision, with many species described by Brake in 2009.
Mixogaster fattigi
Fattig's Ant Fly
Mixogaster fattigi is a species of ant-mimicking hoverfly (family Syrphidae, subfamily Microdontinae) described in 2019. The genus Mixogaster belongs to the tribe Microdontini, a group whose larvae are known to develop within ant colonies as inquilines or predators of ant brood. The specific epithet honors entomologist Delbert La Rue Fattig. The species is part of a lineage exhibiting remarkable morphological convergence with ants, representing an evolutionary strategy to avoid predation while foraging or accessing ant-associated resources.
Myrmecoblatta wheeleri
Wheeler's Ant Cockroach
Myrmecoblatta wheeleri is a small, myrmecophilous cockroach species known for its obligate association with ant colonies. First described by Hebard in 1917, this species inhabits the nest chambers of host ants, where it has been observed in Costa Rica, Guatemala, and Florida. The species represents one of the few documented cases of true myrmecophily in cockroaches, having evolved specialized adaptations for life within ant societies. Its common name honors the American entomologist William Morton Wheeler, who conducted pioneering studies on ant ecology and myrmecophilous organisms.
Myrmecocystus kennedyi
Kennedyi-group Honeypot Ants
Myrmecocystus kennedyi is a species of honeypot ant in the subgenus Endiodioctes, first described by Snelling in 1969. The species is native to arid and semi-arid regions of the western United States and western Mexico. Like other honeypot ants, this species is characterized by specialized replete workers that store liquid food in their distended abdomens. The species has been documented as a host for myrmecophilous beetles in the genus Cremastocheilus.
Myrmecophilidae
Ant Crickets, Ant-loving Crickets
Myrmecophilidae, commonly known as ant crickets or ant-loving crickets, are a small family of Orthoptera comprising fewer than 100 species across several genera. These minute, wingless crickets are obligate inquilines that live exclusively within ant nests, where they exhibit specialized morphological adaptations including reduced eyes, elongated antennae, and flattened bodies. The family has a global distribution with records from North America, Europe, Asia, Australia, and Pacific islands, though many species remain poorly documented. Members of this family do not produce sound and lack both wings and tympanal organs.
Myrmecophilus
ant crickets
Myrmecophilus is a genus of minute crickets commonly known as ant crickets, containing the majority of species in the family Myrmecophilidae. These insects are obligate myrmecophiles, living exclusively within ant colonies. Species vary in size from less than 1.5 mm to 4.7 mm, generally correlating with the body size of their host ant species. The genus has a worldwide distribution with numerous described species across Europe, Asia, North America, and other regions.
Myrmecophilus oregonensis
Oregon ant cricket, west coast ant cricket
Myrmecophilus oregonensis, commonly known as the Oregon ant cricket or west coast ant cricket, is a small myrmecophilous cricket species found in the western United States and Canada. Like other ant crickets in the genus Myrmecophilus, it lives within ant colonies and has adapted to a subterranean lifestyle with reduced eyes and enhanced sensory structures. The species ranges west of the Cascade Mountains from southern British Columbia through Oregon, Washington, and most of California.
Myrmedonota
Myrmedonota is a genus of rove beetles (Staphylinidae: Aleocharinae) first described by Cameron in 1920. The genus was first recorded from Mexico in 2013 with the description of two new species, M. shimmerale and M. xipe. Members of this genus exhibit myrmecophilous associations, aggregating toward agitated ants and potentially preying on them. The genus is suggested to be more diverse in the New World than previously recognized, though its taxonomy remains in a state of confusion.
Myrmedophila
Myrmedophila is a monotypic genus of silken fungus beetles (family Cryptophagidae) containing a single described species, Myrmedophila americana. The genus name, derived from Greek roots meaning 'ant-loving,' suggests an ecological association with ants, though specific details remain poorly documented. The group is rarely encountered, with minimal observational records.
Myrmica rubra
European fire ant, common red ant
Myrmica rubra is a widespread Palaearctic ant species native to Europe, now invasive in parts of North America and Asia. Workers are reddish-brown with darker heads, 3.5–5.5 mm in length. The species exhibits complex social structure with both macrogynes and microgynes, and colonies are polygyne and polydomous. It serves as a host for several myrmecophilous butterflies and has been documented transmitting viruses through scavenging behavior.
Myrmoecia
Myrmoecia is a genus of rove beetles (Staphylinidae) in the tribe Lomechusini, subfamily Aleocharinae. The genus contains nine described species distributed across the Holarctic region. Members of this genus are myrmecophilous, meaning they live in association with ants. The genus was established by Mulsant and Rey in 1873.
Neoponera
Neoponera Panther Ants
Neoponera is a genus of ponerine ants restricted to the Neotropics, ranging from southern Texas to southern Brazil. Workers are slender and medium to large in size (6.5–19 mm), while queens are larger and winged. The genus exhibits diverse nesting behaviors, including ground nests in soil and decaying wood, as well as arboreal ant gardens. Some species, such as those in the N. laevigata species-group, are specialized termite predators.
Otidocephalini
antlike weevils
Otidocephalini is a tribe of antlike weevils in the family Curculionidae, characterized by morphological adaptations resembling ants. The tribe comprises at least 6 genera including Laemomerus, Micromyrmex, Myrmex, Oopterinus, Otidocephalus, and Ptinopsis. Members occur in North and South America, with notable diversity in the Amazon and Atlantic Forest regions. Formerly classified as a subfamily (Otidocephalinae), the group now holds tribal rank within Curculionidae.
Ozaena lemoulti
Ozaena lemoulti is a carabid beetle in the subfamily Paussinae with an obligate myrmecophilous lifestyle across all life history stages. Molecular gut content analysis confirms that adults exclusively prey on Camponotus ants, using specialized piercing-sucking feeding behavior rather than typical carabid crushing. First instar larvae are morphologically modified for life within ant nests, possessing long running legs and lacking the burrow-dwelling adaptations found in other ozaenines. This species represents an independent evolutionary origin of myrmecophily within Paussinae, distinct from the tribe Paussini.
Paederinae
Tomcat
Paederinae is a subfamily of rove beetles (Staphylinidae) containing three tribes: Lathrobiini, Paederini, and Pinophilini. The subfamily is notable for containing the genus Paederus and related genera that produce pederin, a potent vesicant toxin in their haemolymph that causes Paederus dermatitis in humans. The subfamily exhibits diverse ecological adaptations including myrmecophily, troglobitic cave-dwelling, and intertidal lifestyles. Over 36 genera and 436 species occur in North America alone, with global distribution across multiple biogeographic regions.
Parcoblatta bolliana
Boll's Wood Cockroach, Boll's Wood Roach
Parcoblatta bolliana is a small wood cockroach species native to the United States, measuring approximately 11 mm in length. Males are slender with long, functional wings, while females are stouter with reduced tegmina and no functional hindwings. First-instar nymphs have been documented living in ant nests of Cremastogaster lineolata in Kansas, though adults are not found in these associations. The species occupies diverse habitats including pine woods, grasslands, and decaying wood debris.
Paussinae
Ant nest beetles, paussines, flanged bombardier beetles
Paussinae is a subfamily of ground beetles (Carabidae) commonly known as ant nest beetles or flanged bombardier beetles. The subfamily includes four tribes: Metriini, Ozaenini, Paussini, and Protopaussini. Many species are obligate myrmecophiles, living within ant nests where they feed on ant brood and reproduce. Some lineages exhibit chemical defense capabilities, and the group displays diverse morphological adaptations including flanged elytra and modified antennae.
Peckhamia picata
antmimic jumper
Peckhamia picata is a North American jumping spider notable for its specialized mimicry of the ant Camponotus nearcticus. Unlike many ant-mimicking spiders that simply resemble ants in appearance, this species has been observed to specifically avoid eliciting aggressive responses from its ant model. The species belongs to a genus distinguished from related ant-mimic genera by convex carapace shape and sharply declivous posterior region behind the third row of eyes. Individuals are active runners that hold their second pair of legs aloft to simulate ant antennae, making them challenging photographic subjects.
Phloeoporina
Phloeoporina is a subtribe of rove beetles (Staphylinidae) within the tribe Oxypodini and subfamily Aleocharinae. These beetles are small, typically myrmecophilous or termitophilous, living in association with ants or termites. The subtribe was established by Thomson in 1859 and contains multiple genera distributed primarily in the Holarctic region. Members are characterized by morphological adaptations for life in social insect colonies.
Pholeomyia
freeloader flies
Pholeomyia is a genus of freeloader flies in the family Milichiidae, comprising more than 30 described species. The genus is notable for its myrmecophilous associations, particularly with leaf-cutting ants. At least one species, P. comans, has been documented as an inquiline in nests of Atta texana, where larvae develop in underground detritus cavities.
Plebejus idas
Idas blue, northern blue
Plebejus idas is a small blue butterfly in the family Lycaenidae, widely distributed across the Palearctic and Nearctic realms. Males display iridescent blue upper wings, while females are brown with orange submarginal spots. The species exhibits notable geographic variation in its ecological relationships, including facultative versus obligate myrmecophily. The critically endangered subspecies P. idas lotis (lotis blue butterfly), native to coastal California, is believed extinct since 1994.
Pogonomyrmex tenuispinus
Pogonomyrmex tenuispinus is a species of harvester ant in the genus Pogonomyrmex. Like other members of this genus, it is a seed-collecting ant native to arid regions. The species was described by Auguste Forel in 1914. As a harvester ant, it likely participates in seed dispersal and ecosystem engineering through nest construction, though specific ecological studies for this species are limited.

Ant-loving Beetles, Short-winged Mould Beetles
Pselaphinae is a species-rich subfamily of rove beetles (Staphylinidae) containing approximately 9,000 to 10,000 described species. They are among the most diverse and abundant beetles in tropical and temperate forest leaf litter worldwide. The group was historically treated as a separate family Pselaphidae but was reclassified into Staphylinidae by Newton and Thayer (1995) based on shared morphological characters with the Omaliine group. Many species exhibit myrmecophilous associations with ants, and some groups such as Clavigeritae are obligate inquilines with extreme morphological specializations.
Pseudomorpha excrucians
Pseudomorpha excrucians is a species of ground beetle in the family Carabidae, described by William Kirby in 1823. It belongs to the subfamily Pseudomorphinae, a group of carabid beetles whose members are often associated with ant colonies. The genus Pseudomorpha is restricted to the New World, and this species occurs in the United States. Like other members of its genus, it likely exhibits myrmecophilous (ant-associated) behavior, though specific details for this species remain poorly documented.
Pseudomorphini
false-form beetles
Pseudomorphini is a tribe of ground beetles (Carabidae) distinguished by their evolutionary divergence from typical carabid body plans. Members are known for obligate associations with ants, living within ant colonies. The tribe includes the recently described Guyanemorpha spectabilis from French Guiana, which exhibits exceptional size and coloration compared to the generally dull-colored Western Hemisphere species. Research on these beetles remains challenging due to their arboreal ant-nest habitats.
Psilocnemis
Psilocnemis is a genus of myrmecophilic beetles in the family Scarabaeidae, established by Burmeister in 1842. The genus contains a single described species, P. leucosticta. These beetles are associated with ants, though specific details of this relationship remain poorly documented. The genus belongs to the tribe Cremastocheilini, a group known for ant-associated scarab beetles.
Publilia
Publilia is a genus of treehoppers (Membracidae) native to North America, with species occurring primarily in the eastern and central United States. The genus is notable for forming dense aggregations on host plants, particularly goldenrods (Solidago spp.), where nymphs and adults are tended by ants in exchange for honeydew. This mutualistic relationship has made Publilia a model system for studying ant-hemipteran interactions and their ecological consequences for host plants. The genus is distinguished from related treehoppers by its relatively unadorned pronotum compared to the elaborate projections seen in many Neotropical membracids.
Reichenbachia spatulifer
ant-loving beetle
Reichenbachia spatulifer is a minute rove beetle in the subfamily Pselaphinae, commonly known as ant-loving beetles. It is one of approximately 70 species in the genus Reichenbachia, a group characterized by their myrmecophilous associations. The species was described by Thomas Lincoln Casey Jr. in 1897 and is broadly distributed across northern North America.
Rekoa marius
Marius hairstreak
Rekoa marius, known as the Marius hairstreak, is a Neotropical butterfly in the family Lycaenidae. Adults exhibit sexual dimorphism in wing coloration, with males showing dark iridescent blue uppersides and females gray. The species ranges from Paraguay to northern Mexico, with occasional strays reaching southern Texas and Arizona. Larvae display complex ecological associations including myrmecophily with carpenter ants and feeding on diverse host plants.
Riodinidae
Metalmark Butterflies, Metalmarks
Riodinidae is a family of butterflies commonly known as metalmarks, comprising approximately 1,532 species in 146 genera. The family is predominantly Neotropical in distribution but extends into the Nearctic, Palearctic, Australasian, Afrotropic, and Indomalayan realms. Members are distinguished by metallic spots on their wings, reduced male forelegs, and frequent myrmecophilous associations with ants. The family exhibits exceptional diversity in wing morphology and coloration, with extensive Batesian mimicry complexes documented in tropical species.
Saprininae
clown beetles
Saprininae is a subfamily of clown beetles within the family Histeridae, comprising over 50 genera and approximately 800 described species. The group is globally distributed but shows notable biogeographic variation, with particular diversity in arid and coastal habitats. Members exhibit diverse ecological associations, including free-living predators, myrmecophiles, and termitophiles.
Sceptobiini
Sceptobiini is a small tribe of rove beetles (Staphylinidae: Aleocharinae) comprising two genera and five described species. All species are obligate myrmecophiles, living symbiotically within ant nests. The tribe exhibits distinct behavioral divergence between its two clades: Dinardilla species actively interact with host ants, while Sceptobius species occupy more peripheral positions in nests.
Scolopostethus
dirt-colored seed bugs
Scolopostethus is a genus of dirt-colored seed bugs comprising more than 30 described species in the family Rhyparochromidae. Species occupy diverse habitats including ruderal areas, weedy lawns, and ant-associated environments. Some species are myrmecophilous, living near ant nests through chemical defense strategies rather than chemical mimicry. The genus has a Palearctic origin with at least one species, S. affinis, recently established in North America.
Scolopostethus pacificus
Scolopostethus pacificus is a myrmecophilous dirt-colored seed bug that lives in close proximity to nests of the velvety tree ant (Liometopum occidentale). Unlike many ant-associated parasites that rely on chemical deception through cuticular hydrocarbon mimicry, this species employs chemical weaponry—releasing volatile compounds from its metathoracic glands to moderate encounters with its aggressive host. Molecular gut barcoding has confirmed that S. pacificus does not feed on its host ant, distinguishing its relationship as commensal or inquiline rather than parasitic. The species is native to western North America.
Sebaga
Sebaga is a genus of ant-loving beetles in the family Staphylinidae, subfamily Pselaphinae, tribe Jubini. It was established by Raffray in 1891. The genus contains a single described species, Sebaga ocampi. These beetles are myrmecophilous, meaning they live in association with ants.
Stereopalpus
antlike flower beetles
Stereopalpus is a genus of antlike flower beetles (family Anthicidae) comprising approximately 11 described species. The genus was established by LaFerté-Sénectère in 1849, with Stereopalpus mellyi as the type species. Species in this genus are distributed across North America, with records from both the United States and Canada. Like other anthicids, members of this genus exhibit ant-mimetic morphology.
Stylogaster
thick-headed fly, needle-tailed fly
Stylogaster is a genus of conopid flies distinguished by extreme morphological and biological specializations. Adults possess an elongated proboscis exceeding body length when extended, and females have a dramatically elongated abdomen folded beneath the body—the 'needle tail' referenced in the generic name. The genus is the sole member of subfamily Stylogastrinae and comprises approximately 92 species with predominant Neotropical distribution. Unlike other conopids that parasitize aculeate Hymenoptera, Stylogaster species are endoparasitoids of orthopteroid insects (crickets, cockroaches) with documented host associations also including various calyptrate Diptera.
Terapus
Terapus is a genus of clown beetles in the family Histeridae, established by Marseul in 1863. It belongs to the subfamily Haeteriinae, a group characterized by associations with ants and termites. The genus is poorly known, with very few observations and limited published information on its biology. Members of Haeteriinae are generally myrmecophilous or termitophilous, living as inquilines in ant or termite colonies.
Theclinae
hairstreaks, elfins
Theclinae is a subfamily of Lycaenidae butterflies comprising hairstreaks, elfins, and related groups. Members are characterized by small to medium size, often with tail-like projections on the hindwings and intricate underside patterns. Many species exhibit myrmecophilous relationships with ants, and larvae possess a specialized dorsal gland (Newcomer's gland) that secretes sugary fluids to attract ant protectors. The group shows high diversity in tropical regions, particularly the Neotropics and Southeast Asia, with fewer migratory species compared to other butterfly groups.
Thorictini
Thorictini is a tribe of carpet beetles (family Dermestidae) established by Erichson in 1846. Members of this tribe are small, compact beetles adapted to specialized microhabitats. The tribe is relatively species-poor compared to other dermestid tribes and includes genera such as Thorictus. These beetles are primarily known from the Palearctic and Afrotropical regions.
Trichopseniini
Trichopseniini is a tribe of rove beetles (Staphylinidae, Aleocharinae) established in 1883. Members of this tribe are small, typically myrmecophilous beetles associated with ant colonies. The tribe is poorly known, with few observations and limited published biological information. Most documented species occur in the Neotropical region.
Trimioplectus
ant-loving beetles
Trimioplectus is a genus of minute ant-loving beetles in the rove beetle family Staphylinidae, specifically within the subfamily Pselaphinae. The genus was established by Brendel in 1890 and contains at least three described species distributed across North America and Australia. These beetles are myrmecophilous, meaning they live in association with ants. Members of this genus are rarely collected and poorly known biologically.
Tyrina
Tyrina is a subtribe of rove beetles (family Staphylinidae) within the subfamily Pselaphinae. It was established by Reitter in 1882 and contains approximately 35 described genera distributed primarily across tropical and subtropical regions, with notable diversity in Asia, Australia, and the Pacific. Members of this subtribe are small, often myrmecophilous beetles that inhabit leaf litter and soil microhabitats. The subtribe is part of the tribe Tyrini, one of the major lineages of the hyperdiverse ant-loving beetle subfamily Pselaphinae.
Vacusus
Vacusus is a genus of antlike flower beetles in the family Anthicidae, established by Casey in 1895. The genus comprises approximately six described species distributed across the Americas, including North America, the Caribbean, and Central America. Members of this genus exhibit the characteristic ant-mimicking morphology typical of Anthicidae, with elongated bodies and pronotal constrictions that create a superficial resemblance to ants. The genus has accumulated over 950 observations on iNaturalist, indicating moderate documentation of its species in the field.
Valda
Valda is a genus of ant-loving beetles in the family Staphylinidae, subfamily Pselaphinae. These beetles are myrmecophilous, meaning they live in association with ants. The genus was established by Casey in 1893 and belongs to the tribe Valdini, which is named after it. Members are small, typically cryptic beetles found in leaf litter and soil habitats.
