Horned Spanworm Moth
Nematocampa resistaria

Observation date: June 07, 2019
Submitted by: tirvine2020
Specimen type: Photograph
Observation notes: This caterpillar eats Russian Elm (Ulmus laevis). Often would wiggle the superior end of its body when moving to assumedly mimic the movement of a tree branch in the wind. Created pupa by cutting bits of leaf and using silk to tie them down. The product was a sort of collage of bits of leaf and silk.
