A southern bee that just barely gets up into the upper coastal plain of North America. This specimen comes from Blackwater National Wildlife Refuge where it found its way tot their lovely pollinator garden. In that same garden its nest parasite, Coelioxys germana provided Maryland's first specimen record. Photography by Wayne Boo.

Melissodes apicata...this is a wetland species that spends its time in and around Pickerelweed and only Pickerelweed. How interesting. Photograph by Dejen Mengis. Photography Information: Canon Mark II 5D, Zerene Stacker, Stackshot Sled, 65mm Canon MP-E 1-5X macro lens, Twin Macro Flash in Styrofoam Cooler, F5.0, ISO 100, Shutter Speed 200.

If all the Pickerelweed in the world would disappear...this species would too. This is Melissodes apicata; a male, as you can see form its longgggg antennae and its young can only be fed pickerelweed pollen.

The most common Melissodes in the Mid-Atlantic area is M. bimaculata. It occurs commonly in gardens and makes its way around many floral plants, unlike many of its cousins which are picky and may only take pollen from one species of plant. This one from Caroline County, MD and Photographed by Amanda Robinson.

White boots on this, our darkest Eastern Melissodes. The most common species, found in gardens as well as parklands. Uses quite a range of plants compared to the more composite oriented other species. Photography by Kelly Graninger.

Melissodes communis from Biscayne National Park at the tip of Florida. Perhaps the most common species of Melissodes in the deep south. Big and hits the yellow composites like most of the Melissodes. Fast flier. The group is known as summer long-horned bees. Picture by Brooke Alexander, shopping by Elizabeth Garcia.

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. Photo by Brooke Goggins.

Many Melissodes...and there are many look just about the same making them yet another difficult group to differentiate. Here is a common eastern one...a species that makes its way to the north of its near look alike. Picture taken by Ashleigh Jacobs, photshopping by Elizabeth Garcia.

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.

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.

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?

Megachile relativa, a relativa (get it?) common species in northern parts of North America. The orangish pollen carrying hairs under the abdomen are uncommon and therefore useful when sussing out this species.
