Erynnis juvenalis larva on Mockernut Hickory (Carya tomentosa) - 9/16/01
The nearest oaks (Quercus phellos) to this larva on hickory was over 75 ft. away, and a species on which I have not yet found Erynnis larvae. Feeding on Carya was very obvious.

Erynnis juvenalis larva on Mockernut Hickory (Carya tomentosa) - 9/21/01
The nearest oak (Quercus alba) to this larva on hickory was over 54 ft (paced off). away, across a heavily traveled road, mostly large trucks at all hours. It was a huge tree, with no limbs for the first 10-15 ft. in height. I don't believe that this larva could have moved off this oak. Feeding on Carya was very obvious.

The nearest oak (Quercus velutina) to this larva on hickory was over 30 ft (paced off). away. Feeding on Carya was very obvious.
