Between 9/16 and 10/13/01, I found nine larvae of E. juvenalis on Mockernut Hickory (Carya tomentosa) and Sand Hickory (Carya pallida). Feeding was very obvious in all occurrences. I have no doubt that Carya is an acceptable secondary host to Quercus for this species.

I have found E. juvenalis larvae on the following Quercus hosts: Q. ilicifolium (Scrub Oak), Q. velutina (Black Oak) Q. alba (White Oak), Q. marilandica (Black Jack Oak), Q. prinoides (Dwarf Chestnut Oak), Q. prinus (Chestnut Oak), Q. stellata (Post Oak), Q. coccinea (Scarlet Oak), Q. phellos (Willow Oak) .
