Tales From The Ranch: Surprise at Night

Cocoon in Opuntia leptocaulis

I generally don’t recommend driving around the in-laws’ ranch at night, particularly in an open-top vehicle. It’s not out of any worry about the local wildlife, although I’m pretty sure that any local mountain lion hungry enough would pluck me out of an ATV if I weren’t paying attention. The real danger comes from overhanging branches (mesquite trees have nasty thorns that will take chunks of meat if you hit them at sufficient speed) and cactus clumps, as well as the occasional steer or deer that won’t move out of the way. The occasional trip at dusk, though, reveals treasure.

Cocoon in Opuntia leptocaulis

Stopping at one particular point, the last of the sun’s rays were just enough to highlight a strange white blotch in a clump of Opuntia leptocaulis cactus. A closer look, and I found two silken lumps among the cactus arms, which I first took to be spider egg cases. A quick check, though showed them to be moth cocoons. What kind, though, I have no idea. Whatever they were, the caterpillars were rather large, about the size of my thumb joint, and the moths may be comparable. Either way, it may be worth a trip back to the ranch in early spring to see what emerged.
