Bee on the Lookout for VT Bees in May

Here are photos of a few of the many bee species that you might see in Vermont in May.

Andrena alleghaniensis

View Bernie's photos at iNaturalist

Andrena bisalicis, female

Andrena-ceanothi,-female

Andrena cornelli, Female

Go to the woods in the Eastern United States, and find a blooming Rhododendron, look for this bee, it specializes in Rhodos and Azalea pollen for its babies. - USGS Bee Lab

Andrena dunningi, Female

A large dark Andrena. This lovely female, in fresh plumage, is relatively easy to identify simply by the orange-brown color of its body hairs along with the nearly black hairs located on its hind legs which it uses to carry pollen to its nest. However, after it's been out in the sun for several weeks it can also turn the same off-white coloration that most of the other Andrena bees have in this group. This is a bee of tree flowers. In particular, it favors Willows but can be found on a wide variety of spring-blooming woody plants, though seemingly avoiding the heath family, which has its own specialists. - USGS Bee Lab

Andrena melanochroa, Female

Andrena robertsonii, female

This small Andrena is around fairly late in the season (May-June) compared to other Andrena and hangs on on woody low shrubs and brambles. Not common an prone to being misidentified as A. brevipalpis. USGS Bee Lab

Nomada denticulata, male

A moderate sized Nomada, a bee that lays its eggs in the nests of bees in the genus Andrena. This species, at least in the male, has a distinctive antennae. You can see it in at least the picture taken of the bee's side that the underside of the antenna is partially eroded away leaving a hollow on each segment. In general, the genus is difficult to identify and there are many taxonomic issues to putting correct and new names on the group. -USGS Bee Lab

Lasioglossum acuminatum, male

 Here is a male Lasioglossum acuminatum (from Wisconsin, thanks Nolan Amon!). L. a. is part of the Big Lasioglossum group. They are all black (no metallic glitterings here) much bigger than the other groups. For technical reasons, they are called the Lasioglossum sensu strictu subgenus, which someone else will explain to you as to why it is Lasioglossum in the "strict sense", but not me. Now, look at those long mandibles. A not uncommon length for L. sensu strictu group males. The females have the usual "I have to do all the work digging the kids home" mandibles that most sensible females in the bee world have, but, really, what use are those long mandibles for you males? They certainly don't dig, in fact, they are really just sex machines donating their sperm to progenitzise themselves into future generations. Do they fight with them?...seems both unwieldy and unlikely since I think the females don't have time to watch Lasioglossum gladiator rounds. Perhaps it is a "look at me" sort of thing, where large mandibles (maybe all oiled up?) increase mating opportunities. Interestingly, the pattern is absent in most of the other Lasioglossum groups, the males mostly have tiny little mandibles, smaller than the females (very reasonable since they don't have to go around digging with them). The exception is a few males in the Hemihalictus subgenus. Why? Why? Why? I have no answer, but am listening to your theories. - USGS Bee Lab

Lasioglossum imitatum, female

The Lawn Bee. Lasioglossum imitatum. If you are looking for bees in any urban/suburban/highly disturbed habitat in the East, you will find this bee. Small even for a Lasioglossum, it loves whatever conditions it loves about lawns and beat up habitats. A survivor, a crow and sparrow bee that surely is not on the list of declining bees species. To save this bee you should put in a ball diamond. Would it be so easy for the rest of the species. Probably fond of small invasive fast food pollen, I am not sure how much quantification there has been of its diet. Id wise, it has wide cheeks and tiny thick bright white prostrate hairs on its abdomen that occur in nice parallel lines (not too obvious in this series of shots). - USGS Bee Lab

Lasioglossum Versans, female

Here is a bee that clearly loves woodlands: Lasioglossum versans. In the obscure morphological vernacular of tiny sweat bees, I identify it by its tiny bulging purple "nose" (supraclypeus) and its complete lack of a hair fan on the base of T1. - USGS Bee Lab

Lasioglossum-vierecki,-unknown

Sphecodes ranunculi, Female

A big species (for a Sphecodes) about 2/3rds the size of a honey bee. - USGS Bee Lab

Remember there are over 350 native bee species in Vermont. Which ones will you see?

-Bugeyed Bernie

The phenology chart below highlights the months each bee species was observed in Vermont as recorded by the Vermont Atlas of Life (VT Center for Ecostudies) as of March 31, 2024. 

 

The bold 'X' indicates the month with the highest number of recorded observations for the species. 

Each species is linked to the VAL  page (see the last column on the right.) 

Each species' name (first column) is linked to its iNaturalist information page.

"Fabre's Book of Insects", "To talk about oneself is hateful, I know, but perhaps I may be allowed to do so for a moment, in order to introduce myself and my studies."

If you are interested in participating it is every Wednesday at 1 PM.  Videos of the class are available on Dan Kjar's site at:http://bio2.elmira.edu/fieldbio/handybeemanual.html

Read Fabre's Book of Insects (PDF hot link). 

Hailed by Darwin as "The Homer of Insects," famed French entomologist Jean Henri Fabre (1823–1915) devoted hours of rapt attention to insects while they hunted, built nests, and fed their families. Working in Provence, in barren, sun-scorched fields inhabited by countless wasps and bees, he observed their intricate and fascinating world, recounting their activities in simple, beautifully written essays.

This volume, based on translations of Fabre's Souvenirs Entomologiques, blends folklore and mythology with factual explanation.
