My recent adventure away from home was along the shore of Lake Superior at Montreal River Harbour (125km north of Sault Ste Marie).... I kept a rough list of butterflies for the adventure, but the highlight was this:
Common Buckeye (in a BOG)
Not sure how many Ontario records are further north than this (only a handfull I assume... Butterflies of Canada (1998) shows one I think)... Was pretty suprising, espicially when it was in a spruce bog sourrounded by decidious upland woods...
Rest of the species (in no order):
Common Roadside Skipper
Pepper and Salt Skipper
Canadian Tiger Swallowtail
