When to see it

Adults occur from late spring to mid-summer peaking in May and June.

Life History

It spins its web in the tops of plants which supply rigidity and suitable structural spaces. The old heads of various umbellifers, docks, thistles and plants like Hypericum are favoured situations. On heathland the spider is very common on heather. The spider is not deterred by the prey's size, which is always bitten in the leg until dead.

UK Status

The species is widespread in Britain, but more scattered in the west and north.
