Chymomyza
I believe C. amoena is the only species we will find in the northeast where you are located. I did a survey of fruit-baited drosophilids in NY and caught a few of these in ground traps.

 
Thanks
To me these appeared to be the same as prior postings of this species, but I could easily miss a distinguishing trait. Glad to have a little extra confirmation.

Drosophilidae: Chymomyza amoena
Not absolutely sure it is amoena, but it is a very common species here.

 
Thanks, Don.
They looked familiar. I hadn't expected a fruit fly to develop in an acorn, although I see in a prior posting of this species Paul Beuk comments that they can develop in chestnuts.
