Orconectes virilis is a species of crayfish known as the virile crayfish or the northern crayfish.

Ecology

Orconectes virilis can be found under stones in lakes, streams and wetlands, where they hide from predators, such as fish. They are identified by the brown of rust-red carapace and large chelipeds, which are usually blue in colour. Orconectes virilis feeds on a wide range of plants and invertebrates, as well as tadpoles and even small fish.

Distribution

Juvenile's greenish colour will turn red on the carapace and blue on the claws with age

Orconectes virilis is found in southern Canada from Alberta to Quebec and in the northern United States, but has become an invasive species in parts of North America outside its native range, and was discovered in the United Kingdom in 2008.[2] It is listed as a species of Least Concern on the IUCN Red List.[3]

Uses

Orconectes virilis is used as fishing bait and as food for humans, and also as aquarium food for carnivorous fish.[4]
