Hydrochara
I agree with Tim - this larva is too large (mature Hydrochara larvae get over 25 mm; Derallus about 8 mm) and gills not correct for a Derallus. The figure in my 2010 FL water beetle guide of an alcohol-preserved Hydrochara larva does not show the detritus-covered lateral gills as well as this live shot does. I would also not expect to find Derallus in Massachusetts - but who knows?

Hydrochara
This is a larva of Hydrochara. Derallus does not get that big and has multiple (3-4) lateral gills per body segment.

Moved from Beetles.
Derallus would be very nice.
