Ray Spider Egg Sac - Theridiosoma gemmosum

Golden brown sac that was suspended by a thread that was forked at the top. The top of the sac has a cap, which is partly pushed off when the spiderlings emerge. Egg sac was about 3 mm long.

Habitat: Bog; I frequently see these egg sacs in this area, but they are difficult to get photos of!
