Andrena nigrihirta, female, Isle Royale National Park, Michigan

This is picture 1 from a 12 picture series by Matt Buffington at the USDA Parastitic Hymentoptera group at the Smithsonian. Matt's group uses a system very similar to ours to photograph and stack this super tiny wasp. Perhaps one of the most spectacular of the eucoiline wasps out there, species of Acantheucoela are native to South America.

The red maple, Acer rubrum, often one of the most dominant trees in deciduous woods in the East. It blooms very early in the spring and provides pollen and nectar to the set of bees, and flower flies, that come out early.

Most people don't realize how important willow trees are to our native bees in North America. They are a major pollen and nectar source early in the spring and they have more specialists than almost any other plant on the continent. Here is one of those specialists. This is Andrena nida. This bee feed it's young only the pollen from Willow.

Pulled from malaise trap sludge, this little male was found in Calvert County as part of a survey of the Hymenoptera of Warrior's Rest Park. Photoshopping by Thistle Droege and photograph by Brooke Alexander.

One of the relatively few fall Andrena bees (most occur on spring wildflowers). This dark species is associated with Goldenrods and Asters...but then again, that is the main nectar and pollen source of the Fall. They also have a tendency to show up in sandy areas and, indeed, this specimen is from the Carolina Sandhills collected by Heather Campbell.

Andrena nuda, Somerset County, Maryland, April 2012, female

Andrena species, Black-tipped Andrena, specimen collected by Jason Gibbs in OmanEvolution has blessed the genus Andrena with over 1500 different species, making it the second richest of all bee genera (Hairy-tongue Bees, Lasioglossum, are first).

Andrena perplexa - This is a male from Talbot County, Maryland, long thin mandibles, wide cheeks and a big for an Andrena. Common in woodland areas, like so many of the Andrena.

A little male mining bee about the size of a grain of rice. Andrena personata is something I associate with sparse fields, not so much lawns. My guess that the usual lawn weeds don't have the right mix of patriotically native flower species it is looking for. Kind of pixie like, is what I want to say.

Sexy Andrena. Yes, the normally black Andrena does have some sexy species. Here is one of my favorites. Andrena prunorum jacketed in amber with ribbing of white fur...or something like that. A common western species that leaked just enough out of the West to show up in Badlands National Park where we were studying the bee fauna of the Park.

Andrena robertsonii - A little bit tricky to identify, but a bee I associate with taller blooming things such as Blackberrries, shrub hollies, and sumacs. Sumacs are definitely an underrated bee plant.

This specimen was shot upside down and then inverted in photoshop to see what it would look like in terms of lighting. Its not bad, but I think I prefer the lighting coming more predominantly from above.

Andrena specularia - This is a prairie bee. I know that because it is from North Dakota and there are no records that I know of east of the Mississippi River. In fact, there are no legit records outside of North Dakota. Other than the mysterious Turtle Mountains, ND is all about prairie. I would like to propose that this become the state's bee.

Various Andrena, adding to the catalog....most with bad hair. Sigh.
