Sheet Weaver

I got to see one of these for the first time while on a cemetery outing near Cisne, IL.  The Sheet Weaver was on top of a tombstone I was working on.
This Sheet Weaver is sometimes called the “red grass spider,” because of its bright color, this spider is quite large for a linyphiid about 1/4 inch, and is easily spotted. It can be recognized by the black tubercle (bump) at the end of its abdomen . It builds webs in grass, usually a few centimeters off the ground. The web is a sheet about 10 centimeters across, but with a large tangle above the sheet to knock down any passing flies into the sheet below. Florinda is most common in late summer, especially August.
