From Fossil Butte National Monument Wyoming...yet another Lasioglossum. Photo by Dejen Mengis.

A bee of western North America. This one was captured in Bryce Canyon National Park, one of the larger "sensu strictu" group of Lasioglossums.

Here is a bee that clearly loves woodlands: Lasioglossum versans. In the obscure morphological vernacular of tiny sweat bees, I identify it by its tiny bulging purple "nose" (supraclypeus) and its complete lack of a hair fan on the base of T1.

Lasioglossum versatum. One of the most common little sweat bees in the East. Particularly common in the cooler mid-latitudes. These bees can dominate the captures in surveys of bee species of a region. Something of a mess taxonomically.

Sand. The Golden Sand Loving Bee. When I think of bees that are sand loving I think of Lasioglossum vierecki. For one, how nice to have a golden orange bee to look at. For second it is common in sandy areas...so if you are going to find a sand specialist in a sand mine, dune, beach, barren, sandhill in the Northeast there you will find this little orange bee.

Lasioglossum nymphaearum, female, Sleeping Bear Dunes National Lakeshore, Michigan, September 2011

The Endangered Karner Blue, Lycaeides melissa samuelis

One of the rarely seen leafcutting bees, this one is Megachile integrella from the sandhills of North Carolina collected by Heather Campbell and photoed by Amber Reese

A set of male and female Macropis ciliata from NH, collected by Michael Veit on transmission lines...part of a David Wagner study of bees and transmission. This bee is special. Not as common as it once was and a specialist on Lysimachia natives. These plants produce oils that the Macropis add to their pollen balls for their babies. No Lysimachia...no Macropis.

Macropis europaea, European Oil Bee, specimen collected by Heinrich Friese in AustriaSometimes an entire group of bees develops a relationship with one group of plants. The 16 little species of Macropis Oil Bees are such a case. They only seek pollen and oil from plants within the genus Lysimachia.

Macropis were once upon a time a much more common group, this is Macropis nuda...all are loosestrife specialists. So, it could be as simple as Loostrife plants are much less common now than they were or it could be something else. Photograph by Dejen Mengis.

Another Macropis from transmission lines from NH and MA. This species (M. nuda) is also a Lysimachia specialist and the female's bright white pollen carrying hairs and likely the hairs under the abdomen soak up oils which are used by the female to add to pollen to create the food for their young. Collected by Michael Veit and part of a study run by David Wagner.

Late breaking new...this was identified by Don Harvey as Macrotera portalis (formerly in Perdita...now its own genus)Bee with Big Head. This is a Perdita...a male collected in Cochise County Arizona by Tim McMahon. Why such a big head. Unclear because sometimes in the same species have small heads.

An obscure bee of the desert, Martinapis luteicornis only is active early in the morning just as the sky begins to lighten. At least one paper indicates that they are specialists on Psorothamnus scoparius or the Broom Dalea.

From Mount Washington in New Hampshire. A new species for New England this species has a boreal distribution and probably is a hold out from colder days, eking out a living in the White Mountains until global climate change turns it into a jungle.

A rather lovely Lasioglossum from Bryce Canyon National Park (L. sisymbrii) als black and white stripes. Common in the West...leaking a bit into the plains, but not much.

Lasioglossum sopinci lives in sand deserts in Eastern North America.

Lasioglossum sopinci, the undescribed male of this sand specialist, found along some lovely powerline...
