Silk Orb Weaver -
females as large as 50 mm
males as large as 8 mm
These are very nice photos of an orb weaver that is not found in Utah
but Chris Calkins was nice enough to let me
post them on my site. Chris took the photos when
she was living in South Carolina. She now lives in Layton,
Utah. The size
difference in the male and female of this species is phenomenal, as you
will see below:
Female back side.
Tiny male approaching the female for mating
mate or, unfortunately, be eaten.
Male spiders usually have a sequence of tapping
they do with their front legs that soothes or
hypnotizes the female so they can approach them.
How cool is this
photo--a mating pair! The Golden Silk Orb Weaver
spins a web that has a golden cast to it, hence
the name of the spider. It is the only species of this genus in
the Western Hemisphere (according to Bugguide.net)
and is only found in the Southeastern US. When disturbed, it will
vibrate in its web and you can see a video
of this, taken by
Chris, on Youtube.
