From what I can find the previous record late anywhere in Ontario was October 1, 2010 Henrietta T. O'Neill also at Pelee so was quite a surprise seeing this one a full 30 days later.
I didn’t come across anything else of interest until just before leaving next to my car was a
Variegated Fritillary, a species I haven’t seen at Pelee since I can remember.
Looking into records it seems the last time it’s occurred here was Sep. 14th, 2019, Bob Yukich, Karen Yukich and the record late was also
Henrietta T. O'Neill reported on October 31st 2000.
With a big gap in days before we can search Pelee again until it opens is unfortunate as surely more unusual species entered the province but with no killing frost in the forecast perhaps its not too late to find something rare or record late before the lep season is truly over.
This year at Pelee has been exceptional with record early and record late dates including a successful Southern Dogface second brood record.
In the coming weeks I plan on a compilation of these records to share with the group out of interests sake.
