Marbled orb-weaver spider / Araneus m. marmoreus. Letchworth State Park, New York, USA.

A marbled orb-weaver spider (Araneus m. marmoreus, in the family Araneidae) spins its silk in Letchworth State Park, near Portageville, New York, USA. Araneus marmoreus is found in most habitats of the world's northern continents. Two main forms of this species are known: the main (nominate) form Araneus m. marmoreus has an orange abdomen with black or brown marbling; while araneus marmoreus var. pyramidatus (found only in Europe, where the two varieties are seldom found together) is much paler, sometimes almost white, with a single dark blotch towards the rear of the abdomen. The female has a body length (excluding legs) of up to 14 mm, while the male is rather smaller at 9 mm.
