Spiny Orb Weaver

Spiny Orb Weaver

The Spiny orb weaver is one of the most colorful spiders in Florida. This spider is commonly referred to as a “crab spider” due to its combination of color, shape, and size. The females are typically about 6-8mm in length and 10-12 mm wide while the males are quite smaller at 2-4mm in length and being slightly longer than the width. They are easy to identify by the 6 reddish orange projections on top of the abdomen and the remainder of the body being white with black spots. Spiny orb weavers have a virtually year-round life cycle, but are most common in October and November. They are capable of producing up to 15 egg masses, each potentially containing between 100 – 250 eggs. The most common places where these spiders can be found are around houses, nurseries, trees and shrubs, and inside screened enclosures. Bites from spiny orb weavers are not known to cause serious effects to humans.
