Marbled Orb Weaver Spider – Araneus marmoreus

Marbled Orbweaver FemaleThis is a huge female spider at 15mm.

Orb weavers comprise a huge family of spiders, with 3500 species worldwide, 180 of which call North America home. These spiders vary greatly in color, shape and size. They have eight eyes arranged in two horizontal rows of four eyes each. Orb weaver males are generally much smaller than the females and commonly lack the showy coloring of their fairer sex.

Males generally avoid their girlfriends unless they are looking to mate, since they risk being eaten.Orb weavers show the greatest range of sizes and appearance than any other family of spiders. Their presence on human’s structures and their conspicuous web probably account for their less-than-welcome status among people otherwise uninterested in such matters. Orb weavers are completely harmless to human and their pets, but still inspire fear in most people.
