Unicorn Caterpillar Moth
Coelodasys unicornis fam. Notodontidae (Hodges#8007)
Host plant(s): redbud, hackberry, willow
Date(s) and location(s): 30 August, 2025 – Tyson Research Center, St. Louis County, MO; 06 September 2025 – Babler State Park, St. Louis County, MO; 15-September, 2025 – Creve Coeur Lake Park, St. Louis County, MO
Notes: Previous to this year, I assumed this species was an oak/hickory specialist. This is obviously not the case. This species is polyphagous and I was surprised at how many I found on willows this year. Look closely at the upper right photo in this gallery for signs that this individual was parasitized.
