Hey everyone, I found this little guy under some bark in a local woodlot (Guelph, ON) today and was wondering if anyone could help me id it (even just to family would be nice). He has a smooth black face with rings of hair around each abdominal segment, my best guess is some type of arctiid moth however I am not very experienced in identifying caterpillars so I am probably wrong but any help would be appreciated, thanks.
