Detailed Description

Intersex. Gynandromorph. Part Male: Park Female. Here is a lovely example. In this case the intersex section is restricted to the head. This is a Nomada of the pygmaea group. pygmaea group indicates that this is probably a group of species, but....I can't tell them apart. Long story. In any case, this cool specimen was found by Don Harvey in the sand area of Jug Bay Wetlands Reserve on the sand side of the Patuxent River in Maryland. It was flying with a big group of its normal compatriots who almost certainly were checking out the Andrena miserabilis nesting there and all were out for an early spring warm spell. Look at the side of the head is female, yellow/black is male. Female has 12 antennal segments, male - 13. Photos by Anders Croft.
