As you can see from the tattered edges of the wings...this is an old bee, meaning it has been out and about for about 5 weeks. This is also a male, one could count the antennal segments (13 in males, 12 in females) but you can also tell by the greatly expanded white front legs, these are used to cover the females eyes during mating....

Megachile mendica is a very common bee, but in this case it is founded on a very rare plant, Ruth's Golden Aster. Collected and photographed by Philip Moore as part of a survey of that plant species and its pollinators from Polk County Tennessee.

Great Smoky Mountains National Park, Blount County

Leaf cutters never seem to end. Here is Megachile petulans, southernish in distribution and with a lovely display of the complicated tongue architecture bees have. Tongue? This structure is so far removed from our tongues it is ridiculous. Really, think of bees and insects as coming from a different planet.

Megachile poeyi, female, A common Caribbean leaf-cutting bee, this one from GTMO Naval Base, in Cuba

More Leaf-cutters from South Texas from my recent trip. Here is Megachile policaris. Big, found on Sunflowers alone roadsides, Note the big cutting tooth on its mandibles used to cut leaves to line its nests. A particularly trim species with nice sharp lines of bright white hairs along the rims of the abdomen.

What a lovely leaf-cutter from the coastal dunes of Florida. I particularly like the stubtle metallic glints on the top of the abdomen. What a fantastic finish this would make to tricky out your yet black car. This species was collected by Anthony Abbate as part of his ongoing survey of Dune bee species. How vulnerable are these bees to sea level rise?

Cumberland Island National Seashore, Georgia

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.

Some rather bad pictures of M. pugnata males. Not sure why I selected this specimen. Terrible hair. But, anyway check out the large expanded front tarsi. Will have to get additional specimens. Collected in WV by Dave Smith who had fabulous numbers of specimens in malaise samples. Still going through them after 10 years.

Megachile inermis, female, Michigan, Sleeping Bear Dunes National Lakeshore

Guantánamo Bay Cuba is not widely known for its bee fauna. But it should be. Sean Brady and I collected there for a number of years and we were able to obtain over one third of all the known bees from Cuba, including several new species. The species here, Megachile lanata, is not a new species and in fact is found throughout the world as a tramp.

A northern leaf-utter. Note all the lovely cutting edges on the mandibles. Found at Pictured Rocks National Lakeshore on the Upper Peninsula of Michigan.

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.

Seems similar to M. bimaculata, this specimen from Key Biscayne National Park, does not conform to the description of South Florida specimens, which are given the subspecies name. M. b. nulla
