Once again, the main progress to report is that we have made more headway on the Lasioglossum identification! We still have about 10,000 Lasioglossum specimens that need identified to species, but we have made great progress!
I also made it through my bowl traps that I set in 2020. Interestingly, most people typically have Lasioglossum versatum or hitchensi as the most abundant Lasioglossum in their samples. However, it turns out my sample site was predominantly Lasioglossum apocyni! This is an otherwise uncommon species with limited range, so cool to see that I had so many. Below is a table of the species that were found at my site.
The apocyni were the most abundant, which meant there was likely a nesting aggregation right at my sampling transect. So 2 years later, I returned to try to get some photographs of the nests. I wasn’t sure if they would still be there, but lo and behold, they were there and in abundance!
The video above shows just how active it was in that tiny patch of dirt! This dirt patch is barely larger than my shoe!
This species is relatively easy to identify (under a microscope) as they have a gena (cheek) wider than the compound eyes, t1 with an open fan and obvious microsculpture, flat, protruding clypeus, and normal scutum (dense punctures laterally and sparser in the center), and normal propodeum.
It also appears to be getting close to their peak season. From our 2020 samples, we collected the most of this species in August.

All for now,
