Solitary bee - Andrena hirticincta - female

Solitary bee - Andrena hirticincta - Female
Petersham, Worcester County, Massachusetts, USA
September 8, 2005
Size: 10mm

Moved from Mining Bees.

A. hirticincta
This is an Andrena (Cnemidandrena) hirticincta female. This species is a Solidago specialist

Solitary bee - female
An intriguing species, of which no equivalent exists here in western Europe. The whitsh facial spots look especially strange. The fur should have been of a brighter, more reddish brown when the insect was younger. The way of collecting nectar (and, most probably, pollen too) on Goldenrod flowers denotes a short-tongued bee. The wing venation excludes any Halictidae. By contrast, it is quite consistent for an Andrenidae, but I can't exclude a Melittidae.

in melittids the scopa is restricted to the tibia and basitarsis
whereas Andrena have extensive femoral and trochanteral scopae

Excellent opinions:-)
I agree with the assessment that this is an andrenid. Look at those bright stripes on the inside margin of the eyes. They are the "facial foveae" that are virtually diagnostic for the family.

to the Andrenidae guide page. Thanks for your professional help on this and the Vespinae species that seem so confusing to me.
