Not having air has probably given me a higher threshold of what's hot inside. I can sleep with inside temps in the low 80s with just a fan and be fine.
For what's it worth, I saw a wholly caterpillar, it was dead, I may or may not have run part of it over with my car, doesn't matter, but it was all black.
I haven't seen an all black one in a long time, couldn't remember when.
