Jumping spiders

Heliophanus cupreus

Copper sun jumper

Despite its shiny black, metallic body, this jumping spider hunts by sight alone, stalking prey across sunlit leaf litter rather than spinning any kind of web.

SizeFemale 4.6 to 5.8 mm, male 3.6 to 4 mm body length
WhenMarch to September

The body is black with a shiny metallic sheen and scattered white hairs, including a pale line behind the eyes and white spots around the edge of the abdomen. Legs are light yellow with black stripes running their length, though a few individuals have uniformly dark legs.

It hunts on sunlit vegetation in damp meadows, forest edges and even coastal shingle, chasing down small insects instead of building a web. Most adults are seen in late spring and early summer, sheltering in a silk cell under a stone or in leaf litter overnight.
