	There are excellent coloured photo's of both species in Laplante, J.-P.
1985. Papillons et chenilles du Quebec et de l'est du Canada. The two
species look completely different, however, the apicalis photo's are males,
the single inclusa one is a female.
	Covell gives a B&W photo of inclusa stating that it is common, especially
northward. Up here in NE Canada I have yet to see inclusa, so far only
apicalis (+ others in the genus).
Hope this helps,
