I think I injured him while trying to move him to a fresh host plant leaf. These larvae make an extra strong silk mat when they are about to molt. They can be injured if you try to take them off this mat. As I have now learned, a better method is to cut the leaf around the larva without disturbing it and pin it to the new host plant leaf Second Instar July 27, 2006 First Instar - Eclosed from ova July 24, 2006 Photo of first instar just after eclosure from ova ©Nicky Davis Ova Collected on Cottonwood July 19, 2006, Little Cottonwood Canyon, Salt Lake County, Utah. 1., left - July 19, 2006 - 1., right - July 24, 2006 ©Nicky Davis Host Plants Cottonwoods, Hoptrees, Maples, Plums, Quaking Aspens, Sycamaore, Willows Back to Top |
