One of several similar looking Clubiona, although this species has much more robust chelicerae than the rest of the genus. Microscopic examination of the genitalia is necessary to confirm identification.

Identification difficulty
Recording advice

Microscopic examination of the genitalia is necessary to confirm identification.


Can be found in most wetland habitats, especially in emergent vegetation at the edge of water and occasionally on sand dunes. In standing water the spider may be seen stalking prey on stems just above the waterline.

When to see it

Adults have been found throughout the year, but mostly in late spring to mid-summer and late summer to early autumn.

Life History

The silk retreat is often easiest to see, woven into a folded reed leaf or Phragmites head, where the female may be found guarding her egg-sac.

UK Status

The species is widespread in much of England from Yorkshire southwards and lowland Wales, but very scattered in south-west England and northern Britain.

Fairly frequent in Leicestershire and Rutland.
