Orb-weaver spiders

Araneus marmoreus

Marbled orbweaver

The marbled orbweaver's swollen orange abdomen gives it the nickname pumpkin spider, though some individuals stay pale yellow with just a single dark rear mark.

WhereDamp forest edges and streamside shrubs
SizeFemale 5 to 20 mm, male 5 to 10 mm body length
WhenJune to October

Females carry a large, rounded abdomen that ranges from bright orange with fine black marbling to pale yellow with a single dark patch near the rear. The legs are reddish brown, sometimes banded with black, and the body is noticeably larger than the male's slender form.

Webs are usually built among shrubs and low branches at the edge of damp woodland, close to streams. The spider waits hidden nearby in a curled leaf or silk retreat, keeping a signal thread attached to the web so it can feel for trapped prey without watching the web directly.
