Phidippus audax - female

Phidippus audax - Female
Corpus Christi, Nueces County, Texas, USA
May 23, 2011
I've found him on a cladode of a species of Opuntia. I think it is Phidippus audax, but not sure.
About his prey I assume to be a moth caterpillar. Just a guess: Melitara caterpilar?
I'm sure that it is not the caterpillar of Cactoblastis cactorum (invasive in our area). I hope that I will never find this caterpillar, which is a great danger to Opuntia species in our area.

I have frequently seen species of Phidippus (at least two species) on Opuntia. Usually they walk active, in search of prey. Sometimes I think they wait in ambush. Usually they try to hide when they see you. I think they are part of the first line of defense of the Opuntia species. I do not know if they are effective against caterpillars of Cactoblastis cactorum (which feed inside of cladodes). But I hope to be if will be necessary.

Thank you!

Opuntia and Phidippus audax
do seem to "get along well." Last November at Edinburg Wetlands (Hidalgo Co., TX) I observed approximately a dozen of these jumpers (imm. and adults) on "one" cactus.
