Oriental Spiny Orb-Weaver Spider

Oriental Spiny Orb-Weaver Spider (Gastercantha geminata), Spiny orb-weavers is a common name for Gasteracantha, a genus of spiders. They are also commonly called Spiny-backed orb-weavers, due to the prominent spines on their abdomen.

Spiny Orb-Weaver spiders can reach sizes of up to 30mm in diameter (measured from spike to spike). Although their shell is shaped like a crab shell with spikes, it is not to be confused with a crab spider. Genus name Gasteracantha derives from the Greek words “gaster,” meaning “belly,” and “acantha,” meaning “thorn.”

Orb-weaver spiders are known for their nets, the spiral wheel-shaped webs that are so often spotted hanging from garden shrubs or between the branches of trees. However, with more than 2,800 species within more than 160 genera worldwide, orb-weavers are the third largest family of spiders
