Erynnis (Duskywing) larva on Corylus americana (Hazelnut) - Newton County, Arkansas.

(Corylus americana), American Hazelnut has not been reported as a host for any Duskywing species. Dale Schweitzer notes that oak feeding Anisota (Oakworm Caterpillars) use Corylus, so this could be one of the oak feeding Duskywings. On 6/15/04 I found a second larva, certainly the same species, on Hickory Carya sp., on the same trail. I had previosly shown (unpublished) that Juvenal's Duskywing (Erynnis juvenalis)commonly used hickory (several species) for a host in NJ, and Arkansas. In addition, the larva had developed yellow sub-dorsal stripes, like E. juvenalis (other oak feeders white). I will continue to watch it develop.


Same larva as above, on 6/15. It is getting ready to molt, and the big bump behind the head is the new head. It will probably be red.

This larva is cerainly the same species as above, but was on Hickory (Carya sp.), a host for Juvenal's Duskywing, on 6/15.

This is the last time the larva was observed on 7-20, It now looks even more like Juvenal's Duskywing (Erynnis juvenalis), particularly the bold yellow stripe. I could not find it on 7-25. It is certainly not Dreamy Duskywing (Erynnis icelus) see: This Link
