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.

This morning when I was talking on the phone with my sister outside, I noticed a spider wrapping up a fly it had caught in its web. I recognized it immediately as a cellar spider, Family Pholcidae, because of its slender body, long legs and the tangled shape of its web. It also has dark markings on the underside of its body.

The larger cellar spiders common around homes in the Southwest have been introduced from Europe. This one looks like the marbled cellar spider, Holocnemus pluchei, because of the marbled white and pinkish-red pattern on its abdomen.

We have a community of cellar spiders that live on the outside of one of the windows where we watch our bird feeder. When the feeder is quiet, we watch the spiders instead.

This week has been very busy, but I do have a minute to post this cute beetle.

Beetles like this one belong to the family Scarabaeidae, which contain the scarab beetles, the dung beetles, and the May or June beetles. Some scarabs are brightly colored like shiny jewels. Others like the dung beetles, are drab or dark brown. Most are easy to recognize with their boxy, square shape. This one is probably picking up a snack of pollen and/or nectar from this flower.
