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.

Andrena spiraeana is one of the set of bees in the Andrena subgenus Trachandrena. One of the characteristics of this relatively distinctive group are the deeply impressed fovea between the compound eyes and the antennae. A spring bee, I associate this species with wooded wetlands...but I may be simply mistaken on that account.

Andrena uvulariae, Female, Recently, this species was known only from the type, but work by Mike Arduser, Joan Milam, and John Ascher have resulted locating additional specimens along the the male. It appears to be a pollen specialist on Bellflowers. This specimen is approximately 100 years old from the Smithsonian collection.

This is a first in what will be a series of pictures from Claire Kremen's Lab at U.C. Berkeley. This is Andrena vanduzeei, an endemic California bee, restricted to the High Sierras. Note the lovely blue metallic notes and surrounding dark hairs. Specimens collected in Yosemite National Park. Picture by Sydney Price.

Male Agapostemon's almost all have this same pattern, Metallicy green on the head and thorax and then striped yellow and black on the abdomen. Females uniformly don't have yellow anywhere. Why is good question as this male yellowness syndrome runs throughout the bee kingdom, cutting across families.

Another bee associated with deep sandy soils. This one also found in a study sand pit reclamation in Anne Arundel County in Maryland. Amazing to think that such metallic green bees are all around us having done their business for millions of years.

Amblycorypha oblongifolia, Oblong-winged katydid, Upper Marlboro, Maryland, July 2012

Amegilla....one of a large group of large Old World bees that blend and fracture colors in wonderful ways. In this case this male Amegilla from Australia from the Laurence Packer Lab bee slots in a whole series of subtly iridescent green hairs amidst a mix of white and black, quite nice and surely a useful design for a rug or tapestry of some sort.

From Kruger National Park: Amegilla atrocincta. Amegillas come in a variety of sizes and shapes, but most are larger than honey bees. Most too are laddered with bold white stripes across the abdomen (A.

An often uncommon spring Andrena, I associate with the Appalachians, this is a male with a sweet yellow clypeus. Collected by MaLisa Spring near Marietta, Ohio. Photograph by Brooke Alexander.

Two different specimens of Andrena geranii. A northernish species that appears to be a specialist on ....geraniums. Notable is the slight blue metallic sheen to the body. Aaman Dengis and Brooke Alexander took the pictures.

Sunflowers. Specifically, the genus Helianthus to separate out the other "sunflower" plants. Only found in North America. So tall and glorious that we have adopted many for our gardens. Thrusting skyward they telegraph their supply of pollen and nectar to the bees that only feed their young pollen of Sunflower. Here is one of them. The appropriately named A.

A larger Andrena...about the size of a honey bee. A spring forager, not well studied, but shows up here and there throughout much of the deciduous forest landscape of the East south of New England. Photo by Kamren Jefferson.

Maine, Collected by Sara Bushman

A specialist on early spring blooming brassicas. This one was collected just a few days ago along a very urbanized and disturbed section of Indian Creek in Beltsville, Maryland. Other than an overstory of trees all the herbaceous material growing seem to be invasive plants.
