Isn't this a boss looking bee? This is Dianthidium singulare. One of the largest Dianthidiums around. Check out the winged plates near the collar of the bee and the shield like tegula that covers the front wing's insertion point into the body. Such a dramatic species.

Coelioxys sayi, female, Patuxent Wildlife Research Center, Odenton, Maryland

Gynandromorph, bilaterally half male/ half female, very rare, the left hand side of this he-she is male (13 antennal segments / lacking pollen carrying hairs on the legs) and the right it female with 12 antennal segments and pollen carrying scopa on the hind legs. The differences are most obvious on the face shot and the underside shot.

Habropoda excellens, Three spotted Digger Bee, specimen collected by K. Moredock in Utah, USADigger Bees in the genus Habropoda occur around the world across middle northern latitudes and are usually plant specialists, collecting pollen from only a small number of all the plant species that might be available.

Halictus brunnescens: probably the largest species of Halictus in the Mediterranean region of Europe, together with its sibling species Halictus quadricinctus. They are usually found on large purple thistles. In early summer you can see the females digging themselves into the flower to reach the nectar. Picture taken by Sara Guerriera.

Halictus ligatus. One of the crow bees of the North America. It occurs almost everywhere and remains common in urban and disturbed sites, where it is just fine with gathering pollen from alien weeds and flower beds.

Gynandromorph. Park male. Part Female. Intersex. We run into these periodically. Maybe something like once every 25,000 specimens or so. This one is Halictus ligatus and was collected by Sara Bushman from Maine as part of her studies of coastal bees. This specimen is a hodge-podge of male and femaleness.

A relatively new invader to North America. Unlike most of the other invasive bees, this is a ground nester, most of the others nest in holes and likely come over as nest stowaways in shipping containers and dunnage.

A nest parasite of Colletes bees, this is perhaps the most common of the Epeolus species in eastern North America. This species main target is likely the common fall Cellophane Bee Colletes simulans.

A lovely study in coffee-colored integument, heavily branched thick bright white hairs and some nicely formed spines on the scutellum (the back part of the thorax). Members of this group are nest parasites on species in the genus Colletes. Another specimen from the Packer Lab.
