Andrena biscutellata
Andrena biscutellata is a mining bee in the family Andrenidae, described by Viereck in 1917. It is a solitary, ground-nesting bee found in North America. Like other Andrena species, it excavates tunnels in soil to create nest cells provisioned with pollen for its larvae. The species belongs to a large genus of early-spring to summer-active bees that are important pollinators of wildflowers and crops.

Heterospilus eurostae
Heterospilus eurostae is a species of parasitoid wasp in the family Braconidae, first described by Viereck in 1917. The genus Heterospilus comprises small braconid wasps, many of which are understudied and poorly documented in the literature. This species appears to be rarely encountered, with minimal observational records available. Its specific host associations and biology remain largely unknown.
Macrocentrus pyraustae
