What a lovely female Anthidium manicatum from Massachusetts. This species is a non-native species that has successfully invaded much of the Eastern parts of North America, in particular it is fond of ornamental gardens containing furry leaved plants which it uses to line its nest.

Anthidium manicatum is an invasive bee that showed up sometime in the 19 eighties in North America. It is particularly fond of garden plants such as stachys and appears to largely be restricted to areas of human occupancy. The specimens come from Massachusetts, and I wish I could recall who gave them to me, but for now I have forgotten.

A gynandromorph is a bee that exhibits characteristics of both sexes. In the other two species (Lasioglossum and Bombus) the split was bilateral..one side male and the other, female. In this Anthidium oblongatum (an introduced species) almost the entire bee is female with the apparent exception of having a seventh abdominal segment and genitalia.

An odd and rare record of an Anthidium that normally occurs far to west in the dry part of the northern Great Plains, in this case it showed up on Isle Royale National Park where other northern prairie species also reside.

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

Andrena wellesleyana is one of the many Andrena species. It is also one of a number of species where the males have extensive yellow on their faces while the females are completely black. I the bulk of species both males and females have black faces.

Of the woodland oriented bees this is regionally the most common one, Andrena carlni, this male is relatively easy to tell because of the black hairs that line the edges of the eyes and the ocelli that are set back from the back of the head. Photography by Amanda Robinson.
