A couple nights ago, I went to Madera Canyon to collect at the Old Baldy trailhead. There were storms in the distance but the sky in the canyon was quite clear. We set up our light in the parking lot and were immediately greeted by Chrysina. These glorious beetles came in droves.
As you can see, we got all 3 species of Arizona Chrysina, a phenomena that I hadn't witnessed before.
This is Chrysina beyeri, in my opinion the most attractive of the 3 species. Gotta love those purple legs!
We also got lecontei and gloriossa, which are both handsome species as well.
