  • Date photographed: July 6, 2013
  • Description: This "Mouse Spider" egg sac was attached to the inside of a clear plastic vial; this is a view from the outside just after the eggs had hatched. You can see the rubbery, pale, immobile spiderlings, as well as the shed egg shells (they look like little white pieces of debris). The spiderlings remain inside the egg sac until after their first molt, when they are able to move around more and disperse. See this additional view of the same egg sac for a size comparison to the mother spider.
