Overview

Hypsosinga pygmaea is a species of orb weaver in the spider family Araneidae, found in North America, Eurasia and southern Africa. It is commonly known as the spotted false pajama spider.

Hypsosinga pygmaea faces significant population declines primarily due to habitat loss from agricultural intensification and urbanization of wetland areas. Climate change and pollution from pesticides used in surrounding agricultural areas further threaten remaining populations of this small orb weaver spider.
