Summary

Description

Intersex. This bee has both male and female sections, a gynandromorph. The only place it was expressed, if I remember correctly, was the face. The bee's left side is male (short scape, more appressed/flattened white hairs, 13 antennal segments (though the end is broken off), and likely a simple rather than 2 toothed tip of the mandible (which you really can see if this picture). Such things happen regularly (likely in all animals including people) and we see them about 1 out of 30k specimens or soish. This specimen collected from Poplar Island in the Chesapeake Bay by Gene Scarpulla, 17:12, 7 May 2021 (UTC)17:12, 7 May 2021 (UTC){{{{{{0}}}}}}17:12, 7 May 2021 (UTC)17:12, 7 May 2021 (UTC)

We Are Made One with What We Touch and See

We are resolved into the supreme air, We are made one with what we touch and see, With our heart's blood each crimson sun is fair, With our young lives each spring impassioned tree Flames into green, the wildest beasts that range The moor our kinsmen are, all life is one, and all is change.

       - Oscar Wilde
