Hentz's orbweaver spider can be quite annoying, they stretch their
large orb webs across wide open spaces, like walks where you can walk
into them in dim light. But in good light when the web is easy to
see, the large orb (stereotype circular web) web is beautiful in design
and architecture. This spider has stretched the main support line
of her web across about 10 feet of open yard, and about 8 feet off the
ground. Now she is starting on secondary support lines. It
will be after dark when she finishes.
nocturnal, this spider has spent the night head down in the center of
her orb between catches. I was fortunate to get this picture
early in the morning from a distance of only 2 meters. This
spider is easily spooked, and when I moved around to get a picture of
her back she ran to her hiding place for the day.
picture shows the whole orb portion of the web (it's easier to see in
the larger image), the support lines go well beyond this view.
When prey is caught, the spider actually tears a hole in the web in the
process of capture and eating or wrapping the meal for later. So
by counting the holes in the spiders web there are in the morning we
can tell how successful her night's hunting was.
we see the spider wrapping up a juicy catch.
