Ixodes affinis
Ixodes affinis is a hard-bodied tick species distributed across the southeastern United States, Mexico, Central America, and South America. Unlike its congener Ixodes scapularis, this species does not bite humans but serves as a competent vector for Borrelia burgdorferi sensu stricto, the causative agent of Lyme disease. Immature stages feed on birds and small mammals, while adults parasitize larger mammals including deer and dogs. Its expanding range into southeastern Virginia and association with migratory birds has raised concerns about its role in pathogen dispersal.

Oreoneta
A genus of dwarf spiders (family Linyphiidae) established in 1894, comprising approximately 30 species distributed across cold-temperate and Arctic regions of the Northern Hemisphere. Most species inhabit high-latitude or high-altitude environments. The genus was revised extensively by Saaristo & Marusik in 2004, resulting in numerous new species descriptions.
