Taylor’s Checkerspot Butterfly Rearing Program

With the guidance of Biologist Mary Linders of Washington Department of Fish and Wildlife and the Oregon Zoo, SPP partners (Evergreen and WA Corrections) rebuild populations of federally-endangered Taylor’s checkerspot butterflies. We release Taylor’s checkerspots onto south Salish Sea restoration sites, including Joint Base Lewis-McChord and Glacial Heritage Preserve. Since 2011, SPP program participants have reared and released more than 18,000 caterpillars and adult butterflies. More than 27 incarcerated technicians have received training, four graduate students have coordinated the program, and seven WA Corrections staff have served as liaisons. Partners have issued 15 SPP certificates for incarcerated technicians completing training in the program

The Oregon Zoo established the first rearing program, and made excellent progress toward reestablishing Taylor’s checkerspot populations. In 2011, partners built a second facility to breed and rear this species at Mission Creek Corrections Center for Women (MCCCW), doubling program capacity. Funding came from Joint Base Lewis-McChord and US Fish and Wildlife Service.

The Taylor’s checkerspot butterfly (Euphydrayas editha taylori) is a beautifully adorned butterfly, checkered with orange, white, and black spots. Once abundant in the grassland prairies of the Willamette Valley, Puget Sound, and south Vancouver Island, its populations have dramatically declined since 2001 and are now only found in scattered sites within their native range. The butterfly was federally listed as endangered in 2013.

The program is housed in a small, purpose-built greenhouse with UV transmitting glass that provides the butterflies with appropriate light for key metabolic activities. SPP’s program coordinator is an Evergreen graduate student who receives training from the Oregon Zoo’s endangered butterfly lab. In turn, the coordinator guides and teaches three to four inmate-technicians. MCCCW is pleased to host the program. The prison’s staff give invaluable support: they helped build the greenhouse, contribute to maintaining and improving the facility, and provide day to day supervision of the technicians.

The butterfly technicians work meticulously year-round  to successfully rear and breed the butterflies. They feed and care for the butterflies, track and maintain genetic lineages and pairings, observe exacting hygiene protocol, collect detailed data on all life stages, and enter data into an Access database. While the caterpillar larvae sleep through the fall and early winter (diapause), the technicians compile data, update rearing protocols, and write season’s-end reports.

Butterfly technicians also participate in scientific research. One project considered oviposition preference, helping to determine which native host plants Taylor’s checkerspot prefers for egg laying. Results revealed endangered golden paintbrush (Castilleja levisecta) to be most favorable, a plant species that no longer overlaps with the butterfly in the wild, but may have been a historical host…and could be again in the future!

The Taylor’s checkerspot butterfly program has proven transformative for some technicians. Liz Louie worked with the butterflies for more than two years, and likened her time at MCCCW to the life-cycle of a butterfly:

Metaphorically, the butterfly symbolizes re-birth, new life and beginnings…Larvae will sometimes go into second diapause (D2) if they feel conditions are not right. Maybe there’s not enough food, so the larvae will go back to sleep. Similar to D2 larvae, women come in and out of prison. They may not have gotten what they needed from prison the first time, or they lack outside support to help them be successful. But for me personally, at my age, it’s good to know that the final stage is a butterfly. It means the most beautiful stage of my life is yet to come. All the other stages have been in preparation for that final one.
