Last September, on a guided walk at DeKorte Park, Julie McCall found the caterpillar in the photo above.

On this blog, we asked readers for their help in ID-ing it. One reader suggested it was an Eastern Tent Caterpillar. Patrick Carney suggested Fall Webworm Caterpillar.

We then e-mailed butterfliesandmoths.org to see what they thought  — and then forgot all about it. This week we finally heard back:

Thank you again for your submission of Record 927588 to the Butterflies and Moths of North America database on September 3, 2014. Your sighting has been accepted, and your regional coordinator has verified your submission as _Hyphantria cunea_.  

(Probably better  known as Fall Webworm Caterpillar. Thanks, Patrick!)

For those looking ahead to warmer days and nights, a link to the group’s home page is here.
