As an amateur, I'd say my specialty is moths, but I also enjoy many other insects and arachnids.
My main project at this point is Essex County, Ontario Moths (http://www.essexcountymoths.com/).
I'm doing what I can to help fill in the guide, and I've contributed quite a few "firsts" for Canada, Ontario, Maine, and New Hampshire. I also have one "first" for the guide (Ochlerotatus grossbecki).
