Neomochtherus pallipes
Devon red-legged robber fly
Neomochtherus pallipes, commonly known as the Devon red-legged robber fly, is a species of robber fly in the family Asilidae. The species is listed as Critically Endangered in the UK and is endemic to or strongly associated with the Devon region of southwest England. It inhabits species-rich grasslands where it serves as a predator of other insects. Conservation efforts for this species are tied to habitat management practices including cattle grazing that maintains structural diversity in grassland swards.

Pacifastacus leniusculus
Signal Crayfish
The signal crayfish is a large North American freshwater crayfish introduced to Europe in the 1960s to replace declining native fisheries. It has become one of the most ecologically impactful invasive decapods in Europe, outcompeting native crayfish and serving as a carrier of crayfish plague (Aphanomyces astaci). The species establishes self-sustaining populations rapidly, with six age cohorts documented within a few years of introduction. It shows sex- and size-specific coloration patterns, with males displaying more saturated and brighter ventral claw surfaces than females, suggesting a role in intraspecific communication.
