Recorded altitude range

Species text

T. sisyphium is widespread throughout much of southern Britain but apparently becomes much more localised and scattered in the north. Globally it has a wide Palaearctic Distribution: (Platnick 1998) and is widespread in western and central Europe.

Habitat and ecology
T. sisyphium constructs an inverted cup-shaped retreat, which it covers with plantdebris. Below its retreat the spider spins a typical Theridiidae tangle web. This species is typically found on gorse bushes and heather on open ground, but can also be found on oak, blackthorn, nettles, juniper and thistles. Adults are found in early to mid-summer, with most males in May and June and most females in June, but occasionally persisting until October. Single, spherical blue-green egg-sacs are produced between June and August, slightly earlier than T. impressum, and are kept within the retreat. Emergent spiderlings are fed orally by the female.
