Hoplitis pilosifrons, f, md, eastern neck nwr, side

The Blue-eyed Bee. Hoplitis pilosifrons. One of the Megachilidae...they tuck pollen under their abdomen to carry to their nests rather than on their legs like the classic honey bee model. Collected at Eastern Neck National Wildlife Refuge ...a refuge not created for bees, but now embracing their bee communities with plantings and management.

Hoplitis sambuci, m, back, Bray 2, CA

A large Hoplitis from the West Coast. Specifically from Yosemite National Park. Am still mystified by this genus, they are always around in small numbers, but never seem to be a "player" like some of the other genera, if you know what I mean. The specimens were collected for a project done by Lauren Ponisio - Study led by L.

A small, hole nesting bee, collected in Charles County Maryland, Hoplitis simplex is uncommonly found and is a specialist on the plant genus Phacelia. Bee specialists such as this little Hoplitis are fundamentally linked to the world's plant biodiversity...not Phacelia...no H. simplex. Photograph by Hannah Sutton.

Hoplitis spoliata, f, right, Kent County MD

A large Hoplitis, that occurs throughout most of North America East of the Rockies. Occurs in low numbers at most locations, in the Mid-Atlantic is is a June bee and associated with what would appear to be mostly Woody blooming plants. Something to consider in your planting pollinator plans... don't forget the blooming shrubs and small trees.

Hoplitis truncata, m, face, Prince George's Co., MD

Hoplitis truncata. An uncommon Hoplitis that shows up here and there, but never in large numbers. Not well known and its roll and preferences in the world of flowers is also unclear. This is a rather ratty male I collected somewhere near home...will have to keep my eyes open for additional specimens.

Bluets, or Quaker Ladies. Their delicate loveliness does not quite shouw up in these pictures...forming little clumps in poor soils and a part of spring I wait for each year. Specimen and photos from Helen Low Metzman.

Hylaeus basaliis, F, Back, NY, Gravel Pits

The genus Hylaeus is referred to as the Masked Bee group. Most species have yellow vaguely mask-like yellow/white markings on their face. Not this one. It is distinctive in the absence of yellow. Looks like a wasp, does it not? This is because is carries its pollen and nectar loads internally and so the normal hairiness of most bees can be dispensed with.

emerald ash borer, head, md

Destroyer of Ash, this is Agrilus planipennis an invasive Buprestid that has invaded North America where it feeds on Ash. trees. At this point all ash trees in North America are threatened and could ecologically eliminate them from North American forests. On the other hand it is a beautiful Buprestid beetle that simply was brought to the wrong place.

The poster child for rare bees of concern in North America. This is Epeoloides pilosula, collected on David Wagner's study of the conservation landscape of transmission lines. This is a nest parasite of Macropis oil bees. In this study they found both M. nuda and M. ciliata uncommon bees in themselves.
