Edit: noon... after a several hours driving about NE of Barstow it seems that while many areas received rain, it was not a "soaker". No aleates flying that I could find. Will keep looking.
Some areas did get quite a bit of rain earlier, but most of the larger species aren't going to fly until it starts to dry out a bit. I highly doubt anything will fly tonight, and if those areas are wet enough, or it's cloudy in tomorrow morning they probably won't fly then either. The nocturnal fliers would most likely fly tomorrow night, and if it's sunny the diurnal would probably fly Saturday morning. I'll be heading up there Saturday to check out a few areas that got decent amounts of rain.
Honeypot ants I'm asking about are the navajo and the mexicanus for their yellow color
Probably not going to find M. navajo or M. mexicanus in the Riverside area. Those are desert species. There are plenty M. mimicus and M. testaceus, but I'm pretty sure they only fly in early Spring around there. BTW, like the two you mentioned, M. testaceus are also light yellow and nocturnal. The queens of that species are brown though.
