Recording advice

Confirmation of this species: "Requires examination at high magnification in good lighting, typically examination of the genitalia." Bee, L., Oxford, G., & Smith, H. (2020). Britain's Spiders: A Field Guide. Second Edition. Princeton University Press.


It is usually associated with marshy places and near to water where it hunts along the banks and on the water's surface thanks to water repellent hairs on its legs.

When to see it

Peak April to June.

Life History

This wolf spider doesn't build a web for catching prey but instead hunts by chasing down small creatures. Courting males have to signal their intentions to the females from afar by employing a form of semaphore. Without this signalling behaviour, the female would probably attack them. The female carries the egg case with her as a furry ball under her abdomen.
