This bee has unusual antenna with knobs on the tips. I have never seen them before. Does anyone have any thoughts? Picture 3 is a bee of the same species for comparision with the antenna.

Answering my own post. It appears there is nothing unusual about the antenna. Males of some species of Megachilie possess this feature.
