Hello everybody. I am fairly new to this forum and I hope that I am not asking a silly question. We have seen many more unusual insects this past summer at our home in Kanata, Ontario (part of the City of Ottawa). It could be that I am just more observant, now that I have been retired for 4 months. I am an Engineer and don't know my insects well. This caterpillar was under our deck railing for the better part of a day and then moved on. Could someone identify it for me please. Thank you. Chris
