Nicky Davis let me take this picture of her female Kukulcania utahana that she and some others
found at Eagle Mountain, Utah on August 21, 2016. Below is a side shot. © Carol Davis 9-8-2016

The male Crevice Weaver, shown below, is often mistaken for
Desert Recluse or Brown
Recluse because of its color. The University of Florida has the best description I've found
on the differences between Kukulcania and the Desert Recluse.
Pam Wheeler found this male Crevice Weaver in Hurricane, Utah (and sees them quite
often). Unlike the Brown Recluse, this spider does not have the violin shape on the
cephalothorax and it has long pedipalps. Pedipalps are the two appendages in the very
front that look like short legs. Kukulcania can help control black widows (as in

I found this female Crevice Weaver (probably Kukulcania hibernalis - Southern House
Spider) in my brother's home in
Utah, hiding in between the carpet and the wall.
The bricks on the outside of his house have many of the familiar crevice webs of these spiders.
Female Kukulcania are usually grey or black with some brown, but still have the long pedipalps
(that you can see in this photo just below the eyes). Pedipalps are not the fangs - the fangs are
hidden out of sight in this picture (below the pedipalps). © Carol Davis 10-18-2008
