As suspected, the cool weather last night kept the moths in hiding. When I turned the light on at dusk it was already well below my 10 C (50 F) threshold, but I put it on anyway. Five moths tallied at the sheet in a couple of hours: four Maple Spanworms and a pinion (I think) whose identity remains a mystery.
The pinion was much too fast for me to manage to catch with a jar, and eventually disappeared under the nearby spruce and didn’t reemerge. I just got one wide-angle shot of it fluttering at the sheet, which, when cropped in tight, doesn’t provide me with enough field marks to be able to identify it, unfortunately.
It’s a shame about the weather, really. Cool nights can really have a negative effect on the productivity of your moth lights. If this had been a beautiful Indian Summer weekend, with nightime lows of 15 C (60 F) or so, I would expect to have had a really interesting assortment of moths for the two nights. Ah well. Perhaps next year.
I hope others had better luck with their sheets! Don’t forget to submit your posts to the next The Moth and Me by October 13 – email your link to next month’s host Lori of Reflections on the Catawba, loriowenby [at] gmail [dot] com, or to myself.
Also, don’t forget that today, Sunday, is International Rock-Flipping Day! Go out and flip a rock – or two, or three – and see what you find underneath. Write about it on your blog and submit your post to Susannah at Wanderin’ Weeta (wanderinweeta AT gmail D0T com) for inclusion in the event’s compilation of participants.

I think, as a leader in the NA movement, you should call this Leave the Porch Light On weekend, and have it earlier in the season. Start pushing that with some of the nature groups like the Nature Canada blog. Next Year.
I gather that National Moth Night in Britain moves around from one year to the next in order to sample from different flight periods and species composition. This year it’s in September, but next year it might be in July, or May, or whatever. I like the idea of Leave the Porch Light On Weekend, I wonder what’s involved in getting something like that going. Probably more people would be likely to jump on board once there’s a functional field guide to use.
