Size: About 5 mm
I see them in South Mountain Park may be once a year. They are there for a day or two then disappear.
Do they bear the black A of University of Arizona on their back?

Thanks. I still wonder why
Thanks.
I still wonder why they rarely come out. When they do, I find them in different locations on lonely desert trails. Looks like some condition prompt them to come out, 40 C weather? but it is mild summer day occurrence, humidity from a thunderstorm?

Not sure, but
I read in one link that they come out after a heavy rainstorm.

There are also comments on this image that suggest they only come out when their prey is available, which also has a short emergence window:



Probably not the same species as yours, though - it's much bigger.

Thanks for the info. I took
Thanks for the info.
I took other pictures last year, I should check if it is weather related but I never hike on this mountain when storms are threatening or immediately after a storm.
