Photo Life History: Heliopetes ericetorum
Caring for Live Female Butterflies: Nectaring techniques
How to Find Eggs:
How to Hatch Eggs: Consolidate eggs into one container
How to Find Caterpillars in the Field: Look for unique skipper nests (Scroll down to find skipper nests for the great white skipper.) Skipper nests on globe mallows can be quite conspicuous.
Caterpillar setups: Open terrariums;
Larva to Pupa: Larva pupates in caterpillar nest by creating a cremaster and girdle.
Number of Broods per Year: 2-3; depending upon area
Overwintering Stage: First through fifth instars
Overwintering Strategies: Your Own Backyard;
Avoiding Diapause Techniques: In order to avoid diapausing larvae in the fall (or any other time of the year), simply provide them with healthy host plant, and they will proceed through to pupa and emerge immediately.
Disease Prevention: In a closed container, change out host plant and remove frass every two to three days. With the open bucket technique, replace hostplant when it dries out and remove frass every time you remove host plant (likely every 3-5 days depending upon the quality of leaves you feed the larvae). Mallow-feeding caterpillars of the Pyrginae are somewhat disease resistant if you take pretty good care of them.
Emergence: Emergence Container
Field Notes: I've had pretty good luck finding immatures in the Mojave Desert of Washington County in near the Red Hill Country north of St. George. Larvae can be found during the month of March on globe mallow at almost any instar.
