Abejas de Primavera (Género Andrena)Autor
mpelikanDescripción
This fuzzy little guy (c. 8 mm) keeps keying out as A. erythrogaster, which would be a new species for Dukes County/Martha's Vineyard. It seems a bit small, with the vertex rather long for that species. But apparently all-black males like this are not uncommon. Cheek shape; long, thin, reddish basitarsi; fairly short clypeus with dense pitting and a magnificent brush of pale hair; F1 slightly longer than F2; terga with no apical fascia and depressed, reddish hyaline margins; sternal subapical fimbriae with sparse long hairs, interrupted medially; and long. slender mandibles with prominent subapical teeth are among the erythrogaster-like traits I was able to capture. Collected from Epigaea repens.

a parasite of Andrena, perhaps miserabilis here. They dig to find nests, and only miserabilis has regularly dirt-plugged nests here at this date.

Female. Found under a pile of loose sand that was probably the start of a nest burrow. I poked at the sand, expecting to find a burrow that had been blocked, and found her instead. After taking photos, I returned her to where I found her.

Same location as a male from a few weeks ago. Many Nomada, and a few provisioning females.

Breeding pair found on the ground. After picking them up, the male refused to release the female, who wiggled around unsuccessfully. Animals were released after photography.

Ground-dwelling, observed digging in soft ground. At least 4 bees observed in area at the time. Pictured are two separate specimens. Exact species unknown by me, but believed to bee Andrena Clarkella?

On Pityopsis falcata, could it be M. dentiventris? Had a color and general impression unlike any common orange melissodes that I've encountered.

After looking through Triepeolus species on BugGuide, I'm wondering if this might be Triepeolus eliseae. I have additional photos if they'd be helpful, but unfortunately only the one (included here in this entry) that shows the bee from the rear - and it's somewhat blurry as the bee was spinning on the flower when I snapped that picture, and it flew away a few seconds later. Bee found on rudbeckia, back yard.

Surprising for me. All over on Dasiphora fructicosa; rather late date. Flowering phenology of Dasiphora varies from place to place, can be as early as June (often August-September in fens around here). Wide vertex and apical areas of tergites, fairly dense punctures on scutum (vs. virginiana). Det confirmed with voucher specimens. Seems these guys and virginiana are probably most plausible Trachandrena in August-September in the northeast...
