• Alphitophagus

  Alphitophagus is a genus of darkling beetles (Tenebrionidae) established by Stephens in 1832. The genus has an almost cosmopolitan distribution. The best-known species, A. bifasciatus, is a cosmopolitan pest of stored products and serves as an intermediate host for the poultry cestode Raillietina cesticillus. A. obtusangulus, described from Croatia in 1904, was recently recorded from France and Greece.

• Alphitophagus bifasciatus

  Two-banded fungus beetle

  Alphitophagus bifasciatus is a small darkling beetle (family Tenebrionidae) with an almost cosmopolitan distribution. The species is frequently associated with stored products and organic matter, and has been documented as an intermediate host for the poultry tapeworm Raillietina cesticillus. It is distinguished from the rare congener A. obtusangulus by its two pale transverse bands on the elytra.

• Felicola subrostratus

  cat biting louse

  Felicola subrostratus is a chewing louse (order Psocodea) and the only louse species known to infest domestic cats. It is an obligate ectoparasite with strict host specificity for felids. Infestations cause pediculosis characterized by pruritus, dermatitis, and alopecia, though some cats remain asymptomatic. Long-haired cats typically experience more severe clinical signs. Despite a broad geographic distribution spanning multiple continents, field reports indicate it is uncommon in pet cats and occurs more frequently in stray, shelter, or cattery populations.

• 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.
