Identification difficulty
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.

Habitat

The spider is typically found on mature oak trees in open situations, in wood pasture, at the edge of woodland rides or in old hedgerows, but it has also sometimes been beaten from other trees such as Field Maple. There may sometimes be a particular association with oak branches where the foliage has been attacked and the leaves have a yellowish-green, reddish and curled appearance. Females have been found with their egg-sac in curled oak leaves.

When to see it

Adults of both sexes have been found between late May and the end of July with most records in June and early July.

UK Status
