Here is a bee from Acadia National Park in Hancock County Maine. The park is one of the few places that has information about its historic bee populations., Resulting in one of the very very few instances of a historic record of any kind of bee populations in North America. An Illustration of How Poorly Known the bee fauna of the continent is currently.

Megachile melanopyga: This species has two generations in a year, with the 2nd generation being very abundant on autumn asters. Collected by the fabulous Jelle Devalez on the mysterious Lesvos Island in Greece. Photo taken by Sara Guerrieri.

Leaf-cutter. The most common leaf-cutter in most of Eastern North America. It carries pollen on the underside of its abdomen and those hairs are distinctly tinged with orange, something found in only a few other eastern Megachile. Photograph by Amanda Robinson.

On the big side of long-horns is Melissodes comptoides...as you move south and to the prairies...you get tricked up with M. communis and all its color variations. Fortunately, there are ways to tell them apart. Often common and found in many open habitats...particularly if you plant some composites for them...which of course ... you are.

Bryce Canyon Utah...not only has awesome geological formations, but also has awesome bees such as Melissodes conrfusa...in fact the dry west has many more species inhabiting it than the moist and lush landscapes of eastern North America. Picture by Sue Boo. Melissodes confusa captured as part of a large National Park service project.

Yellowstone National Park, this Melissodes was found midst the open meadowlands of the park. One of many types of Melissodes a group that usually collects pollen from plants in the composite family. Photograph by Brooke Alexander.

Melissodes dentiventris, male, an uncommon denizen of dry sandy areas, specializing on pollination of composites...particularly maryland goldenaster. Collected in Anne Arundel County Maryland

Pollen, pollen, pollen, pollen, on a Melissodes desponsa...a species usually associated with Thistles so this may well be thistle pollen. Note that while bees may carry loads of pollen on their legs...pollen usually gathers loosely all over the bee and this is thought to be the pollen that does much of the pollination on plants.

Virginia, front Royal Smithsonian project collected in northwest Virginia. A specialist on native thistles, in particular their pollen. This species is vulnerable 2 thistle control measures of the introduced bull and Canada Thistle species. the native species also disappear from areas where control eliminates all thistle.

Captured in Southeast Virginia by students at Old Dominion University. Note that this specimens conforms to more interior specimens but has much less extensive presence of dark hairs on the Mesepisternum.

There are many species of Melissodes and as you can see from this male, they aren't called Long-horn Bees for nothing. All or almost all of these species are summer to fall bees and most are fond to very fond of flowers in the Asteraceae family ... the fall composites by other names.

The most common eastern native Megachile, Megachile mendica. In this case a male, oft confused with M. brevis. Photography by Amanda Robinson.

The male of Megachile mucida, this is one of the leafcutter bees, here even the male has a massive mandible, though it does not involve itself in making or tending nests....note the forelegs which are tucked under the front of the bee, these are widened greatly and are used to cover the eyes of the female when mating.

Great Smoky Mountains National Park, Blount County

A large hole nesting leaf cutter. This is a male Megachile pugnata (subspecies pomona) from Yosemite. Check out the greatly expanded pale segments of the front legs. These are used in mating and lain over the females eyes. People make up all sorts of stories with that information, but we really don't know that details about why that is a useful feature.

The magnificent mandibled Megachile pugnata. Look how long and wide those mandibles are. Its not clear to me why this species requires much longer mandibles than others, it appears to not be cutting out larger pieces of leaves for its nests, but perhaps it is the type, processing and location of the leaf material that is important.
