Allocapnia rickeri
Midwest Snowfly
Allocapnia rickeri is a small winter stonefly in the family Capniidae, commonly known as the Midwest Snowfly. It is one of numerous small, dark stoneflies in the genus Allocapnia that emerge during cold months when few other insects are active. The species has been documented across the central and eastern United States. Like other capniids, it is associated with clean, cold streams and is an important indicator of water quality.

Cleonini
Cleonini is a tribe of weevils within the subfamily Lixinae, comprising approximately 96 extant genus-group taxa distributed globally. All extant members are hypothesized to be flightless despite frequently possessing fully developed wings (macropterous), a unique condition among Lixinae. The tribe exhibits widespread adult morphological homoplasy that obscures phylogenetic relationships, with many genera radiating from a common ancestor with weakly resolved internal branching. Cleonini are primarily associated with arid and semi-arid habitats, including deserts and steppe environments across North Africa, the Middle East, Central Asia, and western North America.

Diamesa
Winter Midges, Snow Midges
Diamesa is a genus of non-biting midges in the subfamily Diamesinae of the family Chironomidae. Adults are commonly known as winter midges or snow midges due to their unusual cold-season activity. The genus exhibits remarkable cold tolerance, with adults active at sub-zero temperatures and larvae inhabiting cold, running waters. Some species display wing dimorphism, with brachypterous (short-winged) forms adapted for ground mating on snow and ice, and macropterous (fully-winged) forms that swarm in flight during spring.

Eugnosta willettana
Eugnosta willettana is a tortricid moth described by Comstock in 1939. The species is known from a limited geographic range in southwestern North America, with records from southern California, southern Arizona, and Mexico. Adults are active during winter months, with flight records from January to February. The wingspan measures 24–27 mm.

Eustala
humpbacked orb-weavers
Eustala is a genus of orb-weaver spiders in the family Araneidae, first described by Eugène Simon in 1895. As of November 2024, the genus contains 87 species distributed primarily across the Americas, from the United States through Central America to South America, with highest diversity in Brazil, Uruguay, and Argentina. Several species have been documented exhibiting specialized ecological relationships, including myrmecophily (living among ants) in Central American species that inhabit ant-defended acacia plants. The genus includes the well-known humpbacked orb-weaver, Eustala anastera, found across North and Central America.

Ixodes affinis
Ixodes affinis is a hard-bodied tick species distributed across the southeastern United States, Mexico, Central America, and South America. Unlike its congener Ixodes scapularis, this species does not bite humans but serves as a competent vector for Borrelia burgdorferi sensu stricto, the causative agent of Lyme disease. Immature stages feed on birds and small mammals, while adults parasitize larger mammals including deer and dogs. Its expanding range into southeastern Virginia and association with migratory birds has raised concerns about its role in pathogen dispersal.

Operophtera
winter moths
Operophtera is a genus of geometrid moths comprising approximately four recognized species, including the economically significant winter moth (O. brumata) and Bruce spanworm (O. bruceata). The genus is notable for its unusual winter-active adult phenology, with adults emerging and mating during cold months when most other Lepidoptera are dormant. Several species have been introduced outside their native ranges, with O. brumata established as an invasive defoliator in North America. The genus has become a model system for studying hybrid zone dynamics, as O. brumata and O. bruceata form a documented clinal hybrid zone in the northeastern United States.
