Order testing
The virile crayfish (Faxonius virilis), native to North America, is a potential invasive threat to the UK’s freshwater ecosystems. While not yet widespread, its introduction through aquaculture or the pet trade poses significant risks. This species is highly adaptable and competes with native crayfish like the white-clawed crayfish (Austropotamobius pallipes), displacing them and potentially spreading crayfish plague (Aphanomyces astaci). The virile crayfish is also known for burrowing, which can destabilise riverbanks and alter habitats.

Active between April and September with greatest eDNA detection probability between May and August.
