From the mountains of western Maryland comes Osmia distincta...lover of Penstemon flowers. Photoshopping by Thistle Droege.

Osmia georgica. A relatively regular, but not overly abundant hole nesting Osmia. While small it is notable for have what looks like growths on its mandibles, making them quite distinctive. These elevations are probably used to help carry mud to the nests while forming partitions between their cells. Photography by Ashleigh Jacobs.

Osmia grindeliae is a widespread western mason bee. It just barely squeaks into Canada and no records as of yet in Mexico. This female was found in Yosemite National Park and collected for a project done by Lauren Ponisio examining the effect of fire diversity on bees (Ponisio et al. Gloebal Change Biol. 2016). Photograph by Samia Shell.

Range Jumper. This range jumper jumped from Illinois to Virginia. There are no records in between. How odd....this is a rare bee in its limited range in the Midwest and to find it all the way in the Mountains of Virginia seems near fantastical, but there it is and more than one specimen too.

A bee I often associate with Sandy areas...this one captured on Cape Cod National Seashore as part of comparative studies of dune loving bees.

This bee is part of a taxonomic mystery spanning the continent. It turns out that the male of this species is very likely named as O. trevoris, by a long ago taxonomist., All specimens were thought to be limited to the West, but....there were these strange Osmia around the Great Lakes that were sometimes called (incorrectly it now seems) O.

Taxonomy and Discovery. One would expect based on what we know about things like plants and birds, that we would largely have figured out what species of bees exist in the Eastern United States...Not so, still much to do for the students of bees.

We have already added the male of this species. As the name implies this species is rufous in its hairs. Check the hairs filled with pollen underneath the abdomen. Collected by Jelle Devalez in the Aegean Islands of Greece. Photography by Brooke Alexander.

Osmia rufohirta - An Osmia from the Grecian Isles that nests in snail shells. Not this specimen as it is a male and does essentially nothing but mate. Lots of reddish hairs on this species as the name implies. Specimen collected by Jelle Devalez.

Another sand loving bee from Cumberland Island, Georgia. Distributed throughout the Southeast. Thistle Droege is the photoshopper and Kamren Jefferson the photographer.

Acadia National Park brings you a common northern Osmia (Osmia simillima)....large and with oddly shortened and modified front legs, which must be important for something. Picture by Sierra Williams, shopping by Elizabeth Garcia.

A somewhat big and somewhat northern Osmia. One of the frustrating things about bees is that entire groups look about the same, such is Osmia.

Terrible specimen, but the only specimen on hand for Osmia subarctica. A male with distinctive upturned gonostyli on its genitalia....as we all kinow..!

A thistle hugging giant of an Osmia..., who can't but love thistles and the several bee species that depend on them. Here is a specialist that depends on pollen from our native thistle plants to provision the cells of its young. Too often our native thistles also are taken out when people spray for introduced bull and Canada Thistles.

Perhaps one of the most colorful Osmia, Osmia versicolor, collected by Jelle Devalez on the Aegean Islands of Greece. Yet another snail shell nester. What would these species do if there were no snail shells and no snails to make them? Photography by Maggie Yuan.
