Observation notes: Where: Found on my backyard concrete patio in Spokane, Wa.
Weather: Sunny. Light breeze. Temperature was in the upper 50s degrees Fahrenheit.
Caterpillar Details: About 2” long at this time. Completely smooth. No hair or horns or other identifiable features. Bright green with one white stripe down the “spine.” Down the sides, I couldn’t tell if they were black stripes or black spots (See picture.)
Behavior: alert and didn’t seem interested in leaves. So we put it on the ground near some bushes which was a honeysuckle bush. Seemed uninterested in our blackberry bush too.
