Green Lynx Spider Spinning an Egg Sac

A very gravid (pregnant) Green Lynx spider is spinning a silk egg sac, into which she will lay her eggs, then aggressively guard for the next several weeks. When she hears spiderlings or feels them moving within the sac, she will tear an exit hole to release her brood. 4:1 magnification, or 4x life-size.

At bottom of photo, note spiderling from her recently hatched first brood, and spiderling's first molt.

Photographed in Long Beach CA.
