Adelpha eulalia in Utah: 

A Photo Life History  (Lepidoptera: Nymphalidae)

Jack L. Harry

Ova deposited on one of the leaf tips of Quercus turbinella (live oak) Young larva creates a perch by chewing away the leaf and extending the vain of the leaf with dung pellets.  This is a very similar larval strategy to North American admirals of the subgenus Basilarchia.  The lab host utilized here is Quercus alba (white oak).
Fourth instar larva is brown and will remain so until it becomes a green fifth instar.  (See next photo.)  Right before pupating, it turns green to brown again.  (Adelpha californica larvae follow a similar color change pattern.) Fifth instar larva on Quercus alba now showing a greenish coloration.
Adelpha eulalia prepupa on Quercus alba. Adelpha eulalia pupa on Quercus alba.  Arizona sister pupae remain in the pupal stage for roughly 8-14 days; depending upon temperatures.
Adelpha eulalia eclosed adult.  Larva pupated right on lab host Quercus alba. Adelpha eulalia eclosed adult basking on Buddleja davidii.
