[Ctleps-l] Southern immigrant butterflies in CT

I would hesitate to refer to Common Buckeye - and even Variegated Fritillary - as a "southern immigrant". Buckeyes colonize the region annually, and I have even found them (i.e. in mint condition) in southern Maine in mid-June which raises suspicion that in some years they may overwinter in the region. Growing up in southern Michigan and southern Ontario, where the winters are on average more severe than around here, the Buckeye was always a common summer butterfly, and on recent visits to Essex Co., (southwestern) Ontario, I always seem to find it.

Similarly, I have actually found worn female Variegated Fritillaries in NORTHERN Maine in May; so again, these may well be overwintering the region occasionally (at least). And in fact, there is at least one PERMANENT colony of claudia in the Quebec City, Quebec region.

So, the Buckeye is better recognized as a Regular Colonist to the region, while the Fritillary - I don't know - occasional colonist???

Certainly the Cloudless Sulphur, along with most of the other things that we look for in the region in late summer and early fall, IS a southern immigrant.....

I found a Common Buckeye two weeks ago well inland at Storrs on a residential lawn

Cloudless Sulphur, Variegated Fritillary and Common Buckeye, three southern immigrants, have all appeared in the state in June.

Fiery Skipper was reported in MA on Saturday, 6/30.

It looks like 2012 will be a good year for southern immigrants in CT.

I speculate that the recent storms in the southeastern US may have broken the drought in that part of the country, resulting in a butterfly population boom that is leading to these southern immigrants making their north.
