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.

Melissodes confusa, F, Face, UT, Garfield County

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.

A pollen specialist. This species gathers pollen from what appears to be entirely the wet meadow growing plant. ironweed. A lovely deep purple aster that when planted in meadows and gardens is almost immediately discovered by this bee even though the region surrounding seems devoid of ironweed.

Ironweed specialist. Well at least the female is a specialist in that she feeds here babies the bright white pollen of this group of plants. If you plant Ironweed in your garden Melissodes denticulatus will show up they are that common (ironweed is common too).

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.

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.
