Good news, the Mexican yellow caterpillar from last week’s Bug of the Week made it to adulthood. I was able to find the chrysalis, which was empty because the butterfly had emerged. The chrysalis is the pale yellow object on the side of the twig. Way to go Mexican yellow!

This week I spotted evidence of another caterpillar on our grapefruit tree. When you see a leaf with ratty edges like this, it can only be a few insects. I was pretty sure I knew which one. Sure enough, when I tipped the leaf over I found it.

Which of the pictures below is the insect I found? I’ll tell you next week what it is and how it is doing.

Not far from where I found the cellar spider last week, I found this caterpillar feeding on a small ironwood tree. Instead of being alarmed that a caterpillar was eating my plant, I was actually pretty excited. I was pretty sure it is the larval form of the Mexican yellow, a very pretty butterfly. If not, then it is a closely related species.

If you are interested, here is a link to the Butterflies of Southeastern Arizona page which shows what the caterpillar might turn into, the Mexican yellow, Eurema mexicanum.

And here is their picture of the larva stage. Do you think it is the same kind, too?

The caterpillar was over an inch long, probably nearly mature. The next day it was gone. Hopefully it crawled away to form a chrysalis in a protected place and I'll be showing you a photo in a few weeks.
