Gynandromorph, Lasioglossum hitchensi, Face, MD, St Mary's County
Gynandromorph, Lasioglossum hitchensi, Face, MD, St Mary's County

Gynandromorph, bilaterally half male/ half female, very rare, the left hand side of this he-she is male (13 antennal segments / lacking pollen carrying hairs on the legs) and the right it female with 12 antennal segments and pollen carrying scopa on the hind legs. The differences are most obvious on the face shot and the underside shot.

Halictus ligatus. One of the crow bees of the North America. It occurs almost everywhere and remains common in urban and disturbed sites, where it is just fine with gathering pollen from alien weeds and flower beds.

Halictus poeyi and its counterpart Halictus ligatus are 2 of the most common bees in Eastern North America. H. poeyi is runs to the south and H. ligatus to the north. There is enough overlap in characters that at this point they are considered indistinguishable. These species are well in the known range of only H. poeyi in St.

Lasioglossum abundipunctum, F, Face, WY, Lincoln County

As we to document the many species of bees that exist in North America, And worldwide, we realize that quite a few of them look like the species, Lasioglossum abundipuntum. The reason is there are many different species of Lasioglossum and they all look about the same, with difficult characters that vary in subtle ways to torment those who have to identify them.

A couple of unprocessed French bees. This is Lasioglossum albipes. One of the most well studied non bumble non honey bees. Sarah Kocher lent these to us from her many studies, so we could picturate them. While they are your basic brown sweat bee thing, upclose there is a charm in how they are put together. At least I am charmed, that is.

Lasioglossum albipes, Polysocial Hairy-tongued Bee, specimen collected in FranceBecause of the very well known biology of Honey Bees some may believe that all bees have complex social lives. However, very few of the more than 20,000 species of bees discovered actually has a complex social life.

Hoplitis truncata, m, left side, 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.

Another set of shots of a masked bee from the Adirondack Mountains. This is a northerish bee...it extends south, but only along the Appalachians. Most of the females (as in this one) have a bit of yellow on the tip of the clypeus. Not uncommon, look for them on flat topped flowers such as Queen Anne's lace. The look is more wasp than bee however.

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.

New State Record for Maryland, April 2012 Collected on Willow blooms in Dorchester County....a very rarely collected bee east of the Mississippi. I don't know any recent records
