Larvae

Feeding Pattern - Larvae leave a lacy pattern on the host plant, Gambel Oak - Quercus gambelii.
Switched to an oak that is columnar- Quercus sp.  on  26 September because gambelii was not as fresh.  This was reported to be Quercus alba (White Oak or English Oak) but Quercus alba doesn't show as a plant that is in Utah.

Host Plant
Have been known to  feed on
Gambel Oak- Quercus gambelii
Oak-Quercus sp. unknown
Dandelion-Taraxacum officinale
Endive - Cichorium endivia
