Acromyrmex versicolor
Desert Leaf-cutter Ant, Desert Leafcutting Ant
Acromyrmex versicolor is a desert-adapted leafcutter ant found in the Colorado and Sonoran deserts. Colonies exhibit pleometrosis, where multiple queens cooperate to found nests, though typically only one queen survives to establish a mature monogynous colony. Workers collect living and dead leaves to cultivate fungus gardens, the sole food source for the colony. The species is notable for forming large, distinctive nest craters covered with leaf fragments and for its flexible foraging behavior that shifts between diurnal and nocturnal activity depending on temperature.

Adalia
ladybugs, lady beetles, ladybirds
Adalia is a genus of lady beetles (Coccinellidae) containing two species: A. bipunctata (two-spot ladybird) and A. decempunctata (ten-spot ladybird). These beetles are aphid predators found across the Palearctic region. Both species exhibit color pattern polymorphism and possess alkaloid chemical defenses. A. bipunctata is known to harbor multiple male-killing symbionts including Wolbachia, Rickettsia, and Spiroplasma, though symbiont phenotypes vary geographically.

Aethes
Conch moths
Aethes is a genus of small tortricid moths (family Tortricidae, subfamily Tortricinae, tribe Cochylini) comprising approximately 70-75 described species distributed across the Palaearctic region. Species are characterized by small size (wingspans typically 8-23 mm), narrow forewings, and often subtle coloration in yellow, brown, or grey tones with variable fasciation patterns. Larvae are generally associated with Asteraceae, feeding in stems, roots, and seed heads of host plants. The genus includes several well-known species such as Aethes cnicana (Thistle Conch) and Aethes hartmanniana that have been subject to intensive ecological study.

Archips podana
Large Fruit-tree Tortrix
Archips podana is a leafroller moth in the family Tortricidae, first described by Scopoli in 1763. It is notable for exhibiting polymorphism in male genitalia, with four distinct morphs differing in the presence or absence of apical and/or lateral prongs on the phallus. The species is widely distributed across Europe and Asia, and has been introduced to North America. Larvae are polyphagous herbivores on deciduous trees and shrubs, with significant economic impact on fruit crops including apple and pear.

Arctia plantaginis
wood tiger, wood tiger moth
Arctia plantaginis, commonly known as the wood tiger moth, is a Holarctic moth species in the family Erebidae. Males exhibit striking color polymorphism with yellow or white hindwing morphs, both featuring black banding patterns that function as aposematic warning signals. The species has been extensively studied as a model organism for understanding the evolutionary trade-offs between predator avoidance, sexual selection, immune function, and thermoregulation. Larvae show predator-induced plasticity in warning signal expression, developing more melanized coloration when exposed to predation risk.

Arphiini
Arphiini is a tribe of band-winged grasshoppers within the subfamily Oedipodinae (family Acrididae). The tribe contains genera notable for remarkable cryptic coloration that matches rock and lichen substrates. Members exhibit striking intraspecific color polymorphism, with individuals ranging from blue-green lichen-mimics to brown and black forms adapted to barren rock surfaces. The tribe is part of a globally distributed group historically treated as the family Oedipodidae.

Callosobruchus maculatus
cowpea weevil, cowpea seed beetle, bean beetle
Callosobruchus maculatus is a seed beetle (family Chrysomelidae, subfamily Bruchinae) commonly known as the cowpea weevil or cowpea seed beetle, despite not being a true weevil. It is a major pest of stored legumes, particularly cowpea (Vigna unguiculata), causing seed losses of 60–100% in infested stores. The species has a cosmopolitan distribution across all continents except Antarctica, having spread globally through human trade of legumes. It exhibits notable sexual dimorphism, with females typically darker and larger than males. The species is widely used as a model organism in evolutionary biology, behavioral ecology, and developmental studies due to its rapid generation time, ease of laboratory rearing, and well-characterized life history.

Camponotus modoc
Western Carpenter Ant, Western Black Carpenter Ant
Camponotus modoc, the western carpenter ant, is a large black ant species native to western North America. Workers exhibit polymorphism, ranging from 7 to 13 mm in length, with dark red legs contrasting against a black body. The species constructs nests in dead wood, including forest logs and human structures, and is known for its mutualistic associations with aphids, particularly Cinara occidentalis on white fir. Research demonstrates trail fidelity and colony recognition abilities, with workers returning to specific aphid colonies even after displacement.

Carebara
Marauder Ants, Carebara Thief Ants
Carebara is a large genus of myrmicine ants comprising over 200 species distributed worldwide in tropical and Afrotropical regions. These ants are among the smallest known, with workers often barely visible to the naked eye. The genus exhibits remarkable worker polymorphism, including specialized soldier castes with phragmotic (door-blocking) head shapes in some African species. Queens are notably much larger than workers, creating one of the most extreme size dimorphisms in ants. Many species are cryptic inhabitants of soil and leaf litter, with poorly known biology.

Cyphomyrmex
fungus-growing ants
Cyphomyrmex is a genus of small, drab-colored fungus-growing ants in the tribe Attini, found primarily in the Neotropics. These ants cultivate fungi in the tribe Leucocoprineae as their primary food source, with most species growing fungal nodules rather than full mycelial gardens. Colonies are typically monogynous and small, rarely exceeding 500 workers. The genus is divided into two species complexes: the strigatus complex (South America only) and the rimosus complex (southern North America to South America). Cyphomyrmex represents a basal lineage among attine ants and serves as sister group to Mycetophylax.

Maevia inclemens
Dimorphic Jumping Spider
Maevia inclemens is a small jumping spider native to eastern North America, notable for its extreme male dimorphism. Adult males occur in two genetically determined morphs of equal frequency: a 'tufted' morph with an all-black body, white legs, and three cephalothoracic tufts, and a 'gray' morph with black-and-white striping and orange pedipalps. Each morph performs a distinct courtship display, and both achieve equal mating success. The species frequents vegetation, fences, and building exteriors.

Melittobia
Melittobia is a genus of tiny parasitoid wasps in the family Eulophidae, notable for extreme polymorphism, complex social behaviors, and highly female-biased sex ratios. Females exhibit three distinct morphs—winged 'fliers,' short-winged 'jumpers,' and wingless 'crawlers'—determined by larval density rather than genetics. Males are blind, flightless, and comprise only about 5% of offspring, produced asexually through arrhenotokous parthenogenesis. The genus attacks prepupae and pupae of solitary bees, wasps, and other insects in their hosts' nests, with some species also parasitizing fruit flies and flesh flies. Several species are well-studied model organisms for genetics, developmental biology, and behavioral ecology, though taxonomic confusion persists due to extreme morphological plasticity.

Pheidole rhea
Pheidole rhea is a highly polymorphic ant species native to the southwestern United States and northwestern Mexico. The species exhibits an exceptional three-tiered worker caste system comprising minor workers, soldiers, and supersoldiers—an unusual degree of physical polymorphism within the genus. Colonies form large, aggressive societies that forage along conspicuous trunk trails to harvest seeds and insects. First described by Wheeler in 1908, this species has become a subject of interest for studying the relationship between morphological specialization and behavioral plasticity in social insects.

Rhopalosiphum
Cherry-Grass Aphids
Rhopalosiphum is a genus of aphids in the family Aphididae comprising approximately 16-17 species worldwide. Species within this genus are significant agricultural pests, feeding on phloem of host plants and causing direct damage to crops. Several species, notably Rhopalosiphum padi (bird cherry-oat aphid) and Rhopalosiphum maidis (corn leaf aphid), are important vectors of plant viruses including barley yellow dwarf virus and maize dwarf mosaic virus. The genus exhibits typical aphid characteristics including polymorphism with both winged and wingless forms, and parthenogenetic reproduction in favorable conditions.

Rhynocoris
Flower Assassin Bugs
Rhynocoris is a genus of assassin bugs in the family Reduviidae, subfamily Harpactorinae. Species occur across Asia, mainland Europe, Africa, and North America. The genus exhibits subsocial behavior with parental care of egg masses, a trait that has evolved independently only six times in Heteroptera. Multiple species have been investigated as biological control agents for agricultural pests, particularly in cotton and other crop systems.

Sphecodina abbottii
Abbott's sphinx
Abbott's sphinx is a North American hawk moth notable for its bee-mimicking flight and highly cryptic larval camouflage. Adults display violet-grey forewings with bark-like patterning and yellow-banded underwings. The caterpillars exhibit remarkable polymorphism, with some forms mimicking grapes while others resemble dead wood.

Sphecophaga
Sphecophaga is a genus of ichneumonid wasps specialized as ectoparasitoids of vespid wasps. Species within this genus parasitize nests of social wasps, with larvae feeding externally on immature wasp pupae. The genus exhibits complex polymorphism in adult forms and cocoon types, and has been widely introduced as a biological control agent for invasive Vespula wasp species. Two recognized species occur: S. orientalis parasitizing Vespa orientalis in the Mediterranean region, and S. vesparum with subspecies in Europe and North America targeting Vespula species.

Stictocephala stimulea
Stictocephala stimulea is a treehopper species in the family Membracidae, first described by Van Duzee in 1914. Treehoppers in this genus are characterized by their enlarged, often ornate pronotum that extends over the body like a helmet or thorn. The specific epithet 'stimulea' suggests possible resemblance to or association with stinging organisms, though this refers to appearance rather than actual sting. Like other membracids, this species likely feeds on plant phloem sap using piercing-sucking mouthparts.

Timema cristinae
Cristina's Timema
Timema cristinae is a small, flightless stick insect endemic to a restricted region of southern California chaparral. The species exhibits striking color-pattern polymorphism with green, striped, and melanic morphs that provide differential camouflage on two host plants: Adenostoma fasciculatum (chamise) and Ceanothus spinosus. It has become a prominent model system for studying ecological speciation, host adaptation, and the interplay between natural selection and gene flow. The species reproduces sexually with females laying single eggs coated in ingested soil, which require soil contact for successful development.

Tortopus
Tortopus is a genus of burrowing mayflies in the family Polymitarcyidae, restricted to six species based on cladistic revision: T. igaranus, T. circumfluus, T. harrisi, T. zottai, T. bellus, and T. arenales. The genus is characterized by distinctive morphological synapomorphies including female parastyli receptors with long anterior furrows, entirely flattened penes, and nymphs bearing two subapical tubercles on mandibular tusks. Nymphs construct U-shaped tunnels in clay banks, a behavior that renders them difficult to sample with standard aquatic survey methods.
