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.
