Witch Hazel Dagger Moth
Acronicta hamamelis (Guenée, 1852) P-no. 931434.5
Host plant: Found on Ozark witch hazel (Hamamelis vernalis)
Date found: 15–16 August, 2026
Location found: Logger’s Lake Recreation Area, Shannon County, MO
Notes: The WGNSS Entomology and Nature Photography groups had a great joint overnight trip to Logger’s Lake this past weekend. Obviously, among the several entomofauna groups we focused on, caterpillars were high on our list. The species pictured here was one of our most exciting finds. During my studies of field guides and online sources to determine new caterpillar species to look for, the witch hazel dagger moth caught my attention. Southeastern Missouri has plenty of its obligate host plant afterall. However, after looking on iNaturalist a couple of years ago, I discovered there were no documentations of this species in our state. Checking with the Heitzman catalogue, I found that there was only one recorded observation in Missouri—from 1889! I still kept this species in mind; there were a few documentations in Arkansas and eastern Kentucky and Tennessee, and as I mentioned, the host is abundant in Missouri.

During our caterpillar hikes this past weekend, we were delighted to find seven Acronicta hamamelis larvae at various stages. I collected a couple to take home and hopefully rear to adults. The more advanced individual spent the next day feeding on my ozark witch hazel and then changed to its warm pre-pupal coloration. It has since made a cocoon and I hope to see an adult eventually.
