That's it: no doubt about it. We have specimens of Sericomyia  
chrysotoxoides Macquart from Chignecto, Baleine, Prospect, Chester,  
East Chester, Bridgewater, Spondu Lake, and East River. Dates range  
from May 30, June 20, July 3, 5, August 10, 12, 23, 26, and even one  
from Nov 1. A handsome looking fly.

FYI: Sericomyia lata (Coquillett), S. transversa (Osburn), & S.  
militaris Walker are also found in NS.

Cheers!

Chris
