Last bumblebee of the year in our neck of the woods? - Bombus ternarius
Crooked Creek trail, Riverside-Albert, Albert County, New Brunswick, Canada October 27, 2015
Data point for Bombus in New Brunswick in late October. I believe this is Bombus ternarius because of the rearward-pointing mark on the thorax, but still very new to these, so parking it in Bombus.
