I agree as well. Thank you both for confirming! It’s interesting that I found the beetles at a location different from that of the cottonwood seeds.

I agree with you Machi. The leaves in the picture are cottonwood and the spotting time would be correct.

These look a bit like cottonwood seeds to me.
