prickly pear cactus bug
While hunting for trapdoor spiders on on a hillside in Herriman, Utah, two young men, Jeffrey and Benjamin
found these bugs on Prickly Pear Cactus. I had never seen them before and thought at the time that
they resembled Squash Bugs in shape. It turns out that they are, like squash bugs, in the family Coreidae (Leaf-footed
Bugs), although their legs do not resemble leaves like the Western Leaf-footed Bug.  This brown bug is an adult
and the immature bugs (nymphs) look like the ones pictured below. © Carol Davis 8-2-2015

Cactus Coreids, who are quite large, suck the juices out of Prickly Pear Cactus and are harmful over time. As
you can see, both the adults and nymphs have red eyes. © Carol Davis 8-6-201

leaf-footed bug on cactus
I was quite surprised at how many of these insects were on each cactus that we inspected. One can
see how they would be detrimental to the growth of the cacti.  These nymphs were about as big as the
adults (12-15 mm) so I'm sure they were doing their share of the damage.  Thanks Benjamin and
Jeffrey for finding these cool bugs! © Carol Davis 8-6-2015
