Bob, The species was known from 2 specimens collected long ago, the type and paratype. Dave Wagner had me on the lookout for the species, as my site is on the Devils River. I photo'd a luma in 21 April 2019, and another on 13 May 2019, but I didn't collect them because I did not identify them. Then, over a three day weekend in late September 2020 I collected 65 of them, and there were plenty more I did not collect. I set up a number of females for eggs, and got 700+ eggs. About half hatched and with several people to raise them, we raised about 100 to adults. As long as fresh guajillo was available to feed them, they were not hard to raise. However, I had so many females laying eggs that I lost track of which female laid which clutch.

Great, is that the plant named Senegalia berlandieri? Is that where you found them laying eggs or as larvae in the wild?

We have not found eggs in the wild. The caterpillars eat guajillo readily from hatching through the last instar, and they refuse other locally abundant "acacia" species. In late 2020 we collected wild caterpillars on guajillo at night with flashlights and with UV (they fluoresce mildly). They were apparently the offspring of the boom in the population, as we collect caterpillars on guajillo year-round and did not see Afilia cats before and haven't seen them since.
