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.

Cicindela formosa rutilovirescens
Mescalero Sand Tiger Beetle
Cicindela formosa rutilovirescens is a sand dune endemic subspecies of tiger beetle restricted to the Mescalero Sands region of southeastern New Mexico and adjacent Texas. First described by Rumpp in 1986, it is distinguished from other C. formosa subspecies by its distinctive greenish-red to coppery coloration. The subspecies is active in late summer and fall, with adults running on open sandy surfaces. It is considered uncommon and patchily distributed within its restricted habitat range.
