Celithemis
pennants, small pennants
Celithemis is a monophyletic genus of eight dragonfly species in the family Libellulidae, commonly known as pennants or small pennants. Species are primarily distributed in eastern North America. Males of multiple species perch conspicuously on vegetation to defend territories and exhibit resource partitioning through differential perch height selection.

Cladotanytarsus
Cladotanytarsus is a genus of non-biting midges (Chironomidae) containing over 80 described species with worldwide distribution, particularly diverse in the Holarctic region. The genus comprises two subgenera: Cladotanytarsus s. str. and Lenziella. Species are primarily lacustrine, with adults often associated with lake surroundings and larvae inhabiting freshwater sediments. Several species have been described from experimentally acidified lakes in North America, demonstrating tolerance to varying pH conditions. One species, C. lewisi, is a significant human allergen source in Sudan.

Molanna uniophila
Molanna uniophila is a caddisfly species in the family Molannidae. Larvae inhabit shallow, sand-bottomed lake margins and construct portable cases from sand grains and organic debris. They exhibit distinctive diel foraging behavior, migrating from sandy substrates to hard surfaces (rocks, wood, macrophytes) during evening and night to feed on periphyton, then returning to sandy areas by day. Adults display sex-dependent antennal dimorphism associated with asymmetric pheromone communication, where only females produce volatiles.

Pacifastacus leniusculus
Signal Crayfish
The signal crayfish is a large North American freshwater crayfish introduced to Europe in the 1960s to replace declining native fisheries. It has become one of the most ecologically impactful invasive decapods in Europe, outcompeting native crayfish and serving as a carrier of crayfish plague (Aphanomyces astaci). The species establishes self-sustaining populations rapidly, with six age cohorts documented within a few years of introduction. It shows sex- and size-specific coloration patterns, with males displaying more saturated and brighter ventral claw surfaces than females, suggesting a role in intraspecific communication.

Tanypus
non-biting midges
Tanypus is a genus of non-biting midges in the family Chironomidae, subfamily Tanypodinae, comprising at least 100 described species. Larvae are aquatic and benthic, occurring in freshwater lakes and other lentic environments. Species within the genus exhibit bioturbation activity that modifies sediment oxygen dynamics. Life cycle patterns vary by species, with some showing multivoltine generations and specific overwintering strategies.
