Acroneuria
common stoneflies
Acroneuria is a genus of large-bodied stoneflies in the family Perlidae, containing more than 30 described species distributed across North America and Asia. Nymphs are predatory and inhabit streams and rivers, where they serve as important bioindicators of water quality. Adults are known for distinctive emergence behaviors, including arboreal emergence in some species. Several species in the genus are experiencing range contractions and population declines due to habitat degradation and climate change.
Artema atlanta
giant daddy-long-legs spider, Giant Cellar Spider
Artema atlanta is a large cellar spider and the largest known pholcid, with a body length of 8–11 mm. It has a pantropical distribution and has been introduced to temperate regions including North America and Europe. The species is commonly known as the giant daddy-long-legs spider. It constructs tangled webs in dark, sheltered locations and exhibits characteristic pholcid behavior of rapid, vibrating movement when disturbed.
Barronopsis floridensis
Barronopsis floridensis is a funnel weaver spider in the family Agelenidae, originally described from Florida. It belongs to the large-bodied B. texana species group, characterized by robust morphology and distinct genitalic structures. Phylogenetic analysis places it in a clade with B. arturoi, sister to a clade containing B. texana and B. jeffersi. The species has been documented in the southeastern United States and the Bahama Islands.
Dusona
Dusona is a large genus of parasitoid wasps in the family Ichneumonidae, subfamily Campopleginae, with 442 described species. It is the most species-rich genus in its subfamily and has a cosmopolitan distribution. Members are morphologically distinctive within Campopleginae and primarily parasitize Lepidopteran larvae.
Eurycercus
Eurycercus is a genus of large-bodied cladoceran crustaceans (water fleas) and the sole genus of the monotypic family Eurycercidae. Species reach up to 6 mm in length, making them among the largest anomopods. The genus contains 16 described species distributed across four subgenera, with a primarily Holarctic distribution and some extensions into the Neotropics and Southern Hemisphere. Species occupy littoral zones of freshwater lakes and ponds, often associated with submerged vegetation.
Tipula collaris
collared crane fly
Tipula collaris is a large crane fly species in the family Tipulidae, distributed across eastern North America from Canada to the southeastern United States. First described by Thomas Say in 1823, this species is characterized by its substantial body size relative to other crane flies. Adults are typically encountered during the warmer months. Like other members of the genus Tipula, the larvae develop in soil or decaying organic matter.
Tropidischia xanthostoma
Square-legged Camel Cricket
Tropidischia xanthostoma is a notably large cave cricket species in the family Rhaphidophoridae, restricted to the Pacific Northwest region of North America. It is commonly known as the Square-legged Camel Cricket. The species was originally described as Raphidophora xanthostoma by Scudder in 1861. Its large size and geographic restriction make it a distinctive representative of the camel cricket group.
