Allonemobius fasciatus
striped ground cricket
Allonemobius fasciatus, the striped ground cricket, is a small ground-dwelling cricket native to North America. It is a model organism in evolutionary biology, particularly for studies of hybridization with its sister species A. socius, reproductive isolation, and life history adaptation. The species exhibits complex diapause strategies including bet-hedging, where females produce offspring with variable developmental phenotypes to spread risk across unpredictable environmental conditions. Populations show altitudinal adaptation in life cycle timing, with photoperiodic regulation of development compensating for shorter growing seasons at higher elevations.

Anthrenus verbasci
Varied Carpet Beetle
Anthrenus verbasci is a cosmopolitan pest species in the family Dermestidae, commonly known as the varied carpet beetle. Adults are small (2–4 mm), rounded beetles with distinctive patterned elytra bearing bands or spots of brown, black, and white scales. Larvae are covered in dense setae and feed on dried proteinaceous material, causing damage to household items, museum collections, and stored agricultural products. The species exhibits circannual control of its life cycle, with photoperiod serving as the primary zeitgeber for synchronizing pupation and adult emergence in spring. Adults feed on pollen and nectar, particularly from umbelliferous plants (Apiaceae) and Asteraceae, and use both olfaction and vision in host plant selection.

Aphis rubicola
Aphis rubicola is a species of aphid in the family Aphididae, described by Oestlund in 1887. The species exhibits holocyclic life cycle with seasonal polyphenism, producing sexual morphs (males and oviparae) in response to short-day photoperiods. Laboratory studies demonstrate that temperature significantly modifies sexual morph production, with lower temperatures enhancing the transition to sexual reproduction. The specific epithet suggests association with Rubus (raspberry/blackberry) as a host plant, though this has not been explicitly confirmed in available sources.

Chrysopa nigricornis
Black-horned Green Lacewing
Chrysopa nigricornis, commonly known as the Black-horned Green Lacewing, is a species of green lacewing in the family Chrysopidae. It is distributed across Central America and North America. The species exhibits a facultative larval diapause during the third instar within its cocoon, induced by short-day photoperiods acting on the first three free-living larval stages. As both larvae and adults, it is predatory, feeding on soft-bodied insects such as aphids.

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.

Euscelis
Euscelis is a genus of leafhoppers in the subfamily Deltocephalinae, characterized by pronounced phenotypic plasticity driven by photoperiodic cues. Species exhibit seasonal wing polymorphism, producing long-winged (macropterous) dispersal forms under long-day conditions and short-winged (brachypterous) reproductive forms under short-day conditions. Males communicate through substrate-borne vibrational signals produced by abdominal tymbal organs, with species-specific songs functioning in mate recognition and reproductive isolation. The genus occurs primarily in the Palearctic region and includes agricultural pests such as Euscelis lineolata, which damages Medicago crops.

Halobates sericeus
Pacific pelagic water strider, Silvery Sea Skater
Halobates sericeus is an oceanic sea skater in the family Gerridae, one of the few insects adapted to life on the open sea. It inhabits pelagic marine environments across the Pacific Ocean and adjacent regions. The species exhibits photoperiod-dependent aggregation behavior, with adults and late-instar larvae forming more frequent and longer-lasting groups under short-day conditions compared to long-day conditions.

Kytorhinus
Kytorhinus is a genus of seed beetles in the subfamily Bruchinae, family Chrysomelidae. The genus includes species that are specialized seed predators of leguminous plants. Kytorhinus sharpianus, the most studied species, exhibits complex multivoltine life cycles with photoperiodically induced larval diapause and shows female-biased sex ratios in field populations. Adults are small beetles that oviposit on host plant pods, with larvae developing inside seeds.

Labidomera
milkweed leaf beetle
Labidomera is a genus of leaf beetles (Chrysomelidae) in the tribe Chrysomelini. The genus includes several species, with L. clivicollis being the most studied and widely distributed. Members are strongly associated with milkweed plants (Asclepias) and related genera. The genus exhibits unusual larval locomotion and participates in Müllerian mimicry rings with other orange-and-black milkweed insects.

Swamp Milkweed Leaf Beetle, Milkweed Leaf Beetle
Labidomera clivicollis is a large leaf beetle specialized on milkweeds (Asclepias spp.). Adults and larvae feed on milkweed foliage, sequestering cardiac glycosides for chemical defense. The species exhibits aposematic orange and black coloration as part of a Müllerian mimicry complex with monarch butterflies and other milkweed feeders. Reproduction is photoperiodically controlled, with short day lengths inducing adult diapause. Larvae suffer high predation mortality, particularly from ground-dispersing predators.

Pissodes approximatus
northern pine weevil
Pissodes approximatus is a true weevil in the family Curculionidae, historically considered a junior synonym of P. nemorensis but now recognized as part of a single widespread species showing geographic variation in life history traits. The species is closely related to P. strobi, with which it can produce fertile laboratory hybrids, but maintains reproductive isolation in nature through breeding site specificity. Populations previously designated as P. approximatus (northern) and P. nemorensis (southern) differ in seasonal activity patterns and critical photoperiods for reproductive maturation.

Protophormia
Northern blow flies
Protophormia is a genus of blow flies (Calliphoridae) containing two recognized species: P. atriceps and P. terraenovae. These flies are distributed across Eurasia and Northern America. The genus has been extensively studied in laboratory settings for circadian rhythms, photoperiodism, and reproductive physiology, particularly in P. terraenovae.

Protophormia terraenovae is a large, metallic blue-green blowfly with a Holarctic distribution. It is the most cold-tolerant calliphorid species, occurring from the Arctic to temperate regions. The species is economically significant as a cause of myiasis in livestock and valuable in maggot debridement therapy due to its selective consumption of necrotic tissue and antibiotic secretions. Its temperature-dependent development makes it a key forensic indicator for post-mortem interval estimation.

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.

Toxorhynchites rutilus
Elephant Mosquito, Treehole Predatory Mosquito, Predatory Tree-hole Mosquito
Toxorhynchites rutilus, commonly called the elephant mosquito, is a large predatory mosquito species native to North America. Adults are distinctive for their iridescent blue-purple coloration, large size, and non-biting habit—they feed exclusively on nectar and serve as pollinators. The larvae are obligate predators that consume other mosquito larvae, making this species valuable for biological control of disease-vector mosquitoes. A single larva may eat up to 5,000 prey larvae before maturing. The species has been employed in biocontrol programs targeting container-breeding Aedes mosquitoes.

Wyeomyia smithii
Pitcher-plant Mosquito, Pitcher Plant Mosquito
Wyeomyia smithii is a specialized mosquito that completes its entire pre-adult development within the water-filled pitchers of the purple pitcher plant, Sarracenia purpurea. It is a top predator in this unique microecosystem, where its presence directly influences bacterial species diversity. The species exhibits remarkable geographic variation in blood-feeding behavior: northern populations are entirely non-biting, while some southern populations may blood-feed after producing an initial egg batch. W. smithii has become a model organism for studying photoperiodism and rapid evolutionary response to climate change, with documented shifts in critical photoperiod over recent decades.
