Adelpha eulalia

Photo Life History: Adelpha eulalia

Habitat:  Mountain Canyons; Desert Hills & Mountains

Host Plants:  Quercus turbinella; Quercus gambellii

Suitable Lab Host Plants: Quercus virginiana; Quercus alba  (Note: This lab host can be especially helpful for those rearing Arizona sisters during the fall months when scrub oaks drop their leaves in October; but white oak leaves remain useable almost through the month of November.)

Caring for Live Female Butterflies:  Nectaring techniques

Methods of Female Oviposition:  Open Screen Cages; Expose caged females to filtered sunlight.  Note.  Unfortunately, female arizona sisters are not very cooperative at laying eggs in the lab.  There is a group of us trying to figure this out a little better.

How to Find Eggs: Look on tips of leaves

How to Hatch Eggs:  Keep egg on original leaf; keep relatively humid.

How to Find Caterpillars in the Field: Isolated host plants; perches on tips of leaves.  Sometimes larvae can be difficult to find amongst all the leaves.  Oddly enough, caterpillars have been found near the Santa Rita Lodge; Madera Canyon, Santa Cruz County, Arizona, on very short stems with just a few leaves  protruding out of the main trunks of  large oak trees.  Also, females oviposit towards the top branches of 10 - 15 foot high Quercus gambellii trees at Pine Valley Campground, Washington County, Utah.

Caterpillar setups:  Open terrariums; Open Bucket

Larva to Pupa:  Caterpillar silks to leaf or twig; creates and attaches cremaster; hanging as a J before pupating.

How to Find Pupae in the Field: 

Number of Broods per Year:  1-3 depending upon location.

Overwintering Stage:  Third instar. 

Overwintering Strategies:  Your Own Backyard; Refrigerator

Post-Hibernation Strategies: 

Avoiding Diapause Techniques:  Expose larvae to 24 hours of light; Healthy Host Plant.   To be honest very few who have reared this butterfly have been able to create conditions where larvae do diapause.  From what I know, only COL. Clyde F. Gillette has been able to do this.  He reports that diapausing larvae do not build hibernacula; but crawl off the leaf to overwinter near the trunk of the tree.

Disease Prevention:  Change out host plant and remove frass every five days.

Emergence:  Emergence Container
