Photo Details - ©Nicky Davis On 26 July 2009 I located some 5th instar antiopa on willows up Butterfield Canyon, Salt Lake County, Utah GPS 40°29' 73" N 111°57'26" W. Elevation 4470 feet Nymphalis antiopa larvae are gregarious in that they like to stay near each other to feed and rest. They were in a sort of loose ball on the willow when they were located.   These larvae  used  a defensive "head-bobbing" movement when they were disturbed, presumably to keep flies and other insects from parasitizing them.  It seemed as if they were at a concert just nodding their heads  to the music. Host Plant: Narrowleaf Willow  Salix exigua Back to Top
