Great information, but please explain the records of the following
species at Point Pelee during recent years:
Funereal Dusky-Wing (2 records / 2 different years)
Ocola Skipper (now recorded 5 different years, only one record elsewhere
Great Southern White
Sleepy Orange (2 records / 2 different years)
If Marine Blue can make it here from the U.S. southwest, I'm sure a
couple of *Fixsenia favonius ontario* can stray to southern Ontario from
somewhere in the northern United States.
[currently 35 miles E of North Padre Island, Texas]

> Fixsenia favonius favonius is very common here in coastal S.C.
