Jeremy Tatum writes: In the November 3 posting, I said I’d look up the date of the last 2017 butterfly. It was a Cabbage White on 2017 November 1. Thus Kirsten’s November 2 sighting of a Cabbage White this year beats last year’s by one day!
We may have seen the last butterfly of the year, but there are still a few invertebrates around, so Invert Alert will remain open, though doubtless at a reduced rate of activity, so please continue to send your observations or photographs in.
