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.

Aulogymnus
Aulogymnus is a genus of chalcidoid wasps in the family Eulophidae, first described by Förster in 1851. Members of this genus are small parasitoid wasps, part of a diverse family that primarily parasitizes other insects. The genus has been recorded from Europe and Asia. Specific biological details for the genus as a whole remain poorly documented in accessible literature.
