Andrenidae
mining bees, miner bees, bulldozer bees
Andrenidae is a large, nearly cosmopolitan family of solitary, ground-nesting bees commonly known as mining bees. The family exhibits exceptional diversity with over 2,000 described species across four subfamilies: Andreninae, Panurginae, Oxaeinae, and Alocandreninae. Most diversity occurs in temperate and arid (warm temperate xeric) regions. The genus Andrena contains approximately 1,700 species, making it one of the most rapidly speciating bee lineages known. Members are typically small to moderate-sized bees with distinctive morphological features including two subantennal sutures on the face—a primitive trait shared with sphecoid wasps—and often possess foveae (depressions) near the upper margin of the eyes. Unlike most bee families, Andrenidae have no known kleptoparasites. Some lineages, particularly within Panurginae, have evolved crepuscular (dusk-active) foraging behavior with enlarged ocelli.
Anthrenus isabellinus
Anthrenus isabellinus is a carpet beetle in the family Dermestidae, native to the Mediterranean region of Europe and North Africa. The species has been introduced to the eastern United States. Like other Anthrenus carpet beetles, its larvae feed on dried animal products including keratin-based materials. Historical taxonomic confusion with the related A. pimpinellae has complicated understanding of its true distribution.
Armadillidiidae
pill bugs, roly polies, pill woodlice, slaters, potato bugs, curly bugs, doodle bugs, Butchy-Boys
Armadillidiidae is a family of terrestrial isopod crustaceans distinguished by their ability to roll into a complete ball (conglobation) when disturbed. This defensive behavior, shared with unrelated pill millipedes and some other arthropods, has made them commonly known as pill bugs or roly polies. The family contains approximately 18 recognized genera and shows highest diversity in Mediterranean karstic regions, with some species having achieved widespread global distribution through human activity.
Bryobiinae
Bryobiinae is a subfamily of spider mites (Tetranychidae) within the order Trombidiformes. Members of this subfamily have been documented from Turkey and Greece, with species collected from agricultural fields and natural habitats. The subfamily includes genera such as Bryobia, Aplonobia, and Mezranobia. New species continue to be described, including recent discoveries from garlic fields and island ecosystems.
Cryptocephalini
case-bearing leaf beetles
Cryptocephalini is a tribe of leaf beetles within the subfamily Cryptocephalinae, characterized by case-bearing larvae that construct and carry protective cases. The tribe comprises approximately 987–988 species in the Palaearctic region alone, with substantial diversity in arid and Mediterranean zones. Some species exhibit myrmecophilous associations with ants.
Cystiphora schmidti
rush skeletonweed gall midge, Rush Skeletonweed Gall
Cystiphora schmidti is a gall midge (Diptera: Cecidomyiidae) that induces small circular to ovoid raised galls on Chondrilla species, particularly Chondrilla juncea (rush skeletonweed). Native to the eastern Mediterranean region from Greece to Iran, it has been introduced to Australia as a biological control agent against this invasive weed. The species completes all immature stages inside plant galls in 24–44 days, supporting 6–7 generations annually in favorable climates. It exhibits strict host specificity to the genus Chondrilla and is heavily parasitised by Eulophid wasps in its native range.
Diaperinae
Diaperinae is a subfamily of darkling beetles (Tenebrionidae) comprising more than 120 genera organized into 11 tribes. The subfamily exhibits considerable ecological diversity, including fungivorous species that inhabit fruiting bodies of bracket fungi, myrmecophilous species that live commensally within ant nests, and free-living forms. Some species display specialized adaptations such as reduced eyes for subterranean life, compact rounded body shapes for physical defense against ants, and cuticular hydrocarbon mimicry of host ant recognition signals.
Ectobiinae
wood cockroaches
Ectobiinae is a subfamily of small to medium-sized cockroaches within the family Ectobiidae, characterized by morphological diversity and taxonomic complexity. The subfamily includes numerous genera distributed across Europe, North Africa, and the Mediterranean region, with several groups showing recent northward range expansion. Taxonomic revisions have revealed extensive cryptic diversity, with new genera such as Planuncus and multiple subgenera established based on detailed morphological analysis. Some species exhibit unusual reproductive strategies including geographic parthenogenesis.
Haploembia
webspinners
Haploembia is a genus of webspinners (order Embioptera) in the family Oligotomidae, containing at least three described species. Native to the Mediterranean region, members of this genus have been introduced and naturalized in California and other areas. These insects are notable for producing silk from specialized glands on their forelegs, which they use to construct protective tunnel systems. Species within this genus exhibit distinct reproductive strategies: Haploembia tarsalis is parthenogenetic, while H. solieri reproduces sexually.
Icosium tomentosum
Icosium tomentosum is a longhorn beetle and the sole species in the monotypic genus Icosium. Native to the Mediterranean region, it has been introduced to California. The species is notable for its larval acoustic behavior: larvae produce audible sounds through mandible scraping against bark and exhibit chorusing behavior, responding to vibrations from other larvae in nearby branches.
Idaea
wave moths, dwarf geometer moths
Idaea is a large genus of geometer moths (Geometridae: Sterrhinae) distributed nearly worldwide. The genus contains numerous small species, many of which are characterized by wavy transverse lines on the forewings that give them their common name of 'wave moths.' Species diversity is particularly high in the Mediterranean region, African savannas, and the deserts of western Asia. The genus was established by Treitschke in 1825.
Iris oratoria
Mediterranean mantis, iris mantis
Iris oratoria, commonly called the Mediterranean mantis, is a medium-sized praying mantis species native to Europe, North Africa, and parts of Asia. The species has been introduced to the southwestern United States, where it was first recorded in southern California in the 1930s and continues to expand its range. Adults reach approximately 6.5 cm in length and are distinguished by violet-brown eyespots on the hindwings that are displayed during threat responses. The species exhibits facultative parthenogenesis and delayed emergence from oothecae as adaptations that may contribute to its invasive success.
Iuridae
The Iuridae are a family of scorpions established by Thorell in 1876. The family comprises six genera—Anatoliurus, Calchas, Iurus, Letoiurus, Metaiurus, Neocalchas, and Protoiurus—with at least 20 described species. Iuridae is distinguished from the large family Buthidae by possessing monocentric chromosomes rather than holocentric chromosomes. The family is part of the order Scorpiones within the class Arachnida.
Nitidula flavomaculata
Yellow-spotted Nitidula, Yellow-spotted Sap Beetle
Nitidula flavomaculata is a sap-feeding beetle in the family Nitidulidae. Native to the Mediterranean Region, it has become naturalized in North America. The species is strongly associated with later stages of decay in mammalian corpses, making it valuable for forensic investigations. Its presence on carrion distinguishes it from many other sap beetles that feed primarily on plant exudates, pollen, or fungi.
Ochthebius
minute moss beetles
Ochthebius is a large genus of minute moss beetles in the family Hydraenidae, comprising at least 460 described species. These tiny beetles are predominantly associated with aquatic and semi-aquatic habitats, particularly supratidal rockpools, coastal marshes, and freshwater spray zones. Many species exhibit narrow habitat preferences and restricted distributions, with numerous endemic taxa. The genus shows significant diversity in the Mediterranean region, Africa, and other parts of the world, and includes several cryptic species complexes.
Praydidae
false ermine moths
Praydidae is a family of small moths in the superfamily Yponomeutoidea, elevated from subfamily rank in 2013 based on molecular evidence. The family includes the economically significant genus Prays, notably Prays oleae (olive moth), a major agricultural pest of olive trees. Members are characterized by their association with woody plants and, in some species, distinct multivoltine life cycles with generation-specific feeding habits.
Pterolonchidae
Pterolonchidae is a small family of minute moths in the superfamily Gelechioidea, comprising approximately 19 species across seven genera. The family has undergone substantial taxonomic revision, with genera reassigned from multiple other families based on cladistic analysis. Species are distributed across every continent except Australia and Antarctica, with notable concentrations in the Mediterranean region, western North America, and southern Africa. Several species have significant ecological and economic importance, including one used as a biological control agent for invasive knapweeds and another that is a major agricultural pest of cereal crops.
Ptilophorus
Ptilophorus is a genus of wedge-shaped beetles in the family Ripiphoridae, comprising at least three described species. The genus is characterized by adults with distinctive antennae—flabellate in males and triangular in females—and elytra that fully cover the abdomen, a trait unique among Ripiphoridae in some regions. Adult activity occurs primarily in spring, with males exhibiting conspicuous perching and scanning behaviors while females seek oviposition sites on dead twigs of living trees. The complete larval life cycle remains poorly known, though parasitic development is hypothesized based on family-level characteristics.
Xanthothrix
Xanthothrix is a genus of owlet moths in the family Noctuidae, erected by Henry Edwards in 1878. The genus contains four described species distributed across western North America and the eastern Mediterranean region. Two species are endemic to California, with one restricted to the Mojave Desert. The genus belongs to the subfamily Stiriinae, a group of generally small, often boldly patterned noctuid moths.
