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.

Melanoplus davisi is a species of spur-throated grasshopper in the family Acrididae, described by Hebard in 1918 from the southeastern United States. It belongs to the large genus Melanoplus, which contains numerous economically and ecologically significant grasshopper species. The species appears to be relatively poorly documented in the primary grasshopper literature of the western United States, suggesting it may be of limited distribution or abundance compared to more widespread Melanoplus species.

nearcticum
Rhopalosoma nearcticum is a parasitoid wasp in the family Rhopalosomatidae. Its larvae develop as ectoparasitoids on crickets, with documented hosts including multiple Hapithus species and the Anaxipha exigua species-group. The species is found in the Americas from the United States to Brazil, though phylogenetic studies suggest at least two genetically distinct Rhopalosoma clades exist in America north of Mexico.
