Key to the Lepidoptera of Canada

A few months ago a magnificent key to the Lepidoptera of Canada (all of them) was published by Jason Dombroskie – a PhD student from the U. of Alberta.  The program is available for windows users only so I haven’t had a good chance to explore it yet – but the PDF is available online and covers the same material.  All known Canadian Lepidoptera are included in this key and most of them down to subfamily or even tribe!  There are 222 taxa, 73 characters and 266 character states that help narrow things down.  This is the first reference of its kind to accurately and completely cover the fauna of an entire country and the first to use a well illustrated and interactive key.  It’s surprising how well known the leps are yet how few good references exist, almost none of which have a usable key.  For everyone out there who has struggled to identify leps before this will be an incredibly helpful resource.  Granted, there are likely a few US moths that could throw a wrench into the flow of things, but by and large I doubt there will be many problems.
