Celebrating another flight season for butterfly technicians

Ms. Stevens and Ms. Christopher painted this banner to welcome Girl Scouts Beyond Bars to the butterfly lab for a day of activities, including a unique Taylor’s checkerspot merit badge designed by Ms. Alexander.

Inmates at Mission Creek Corrections Center for Women (MCCCW) continue to amaze us. Each year, a group of dedicated technicians raise and release thousands of federally-endangered Taylor’s checkerspot butterflies. Not only do these technicians follow rigorous laboratory protocols, they develop their own personal expertise and remain adaptive to the myriad challenges of animal husbandry.

This year we were lucky to have three returning technicians on the team. Jessica Stevens, Cynthia Fetterly, and Susan Christopher have completed multiple seasons in the butterfly lab and they have an in-depth understanding of each life stage. Their experience has taught them how to read these animals down to the finest details, like determining the “instar” of a growing caterpillar or predicting how the weather might influence adult mating behavior. Returning technicians play a crucial role, and it is equally important to recruit new participants. This winter we welcomed Nicole Alexander and Alexis Coleman to the butterfly crew and they began their crash course in Taylor’s checkerspot rearing. By the end of the flight season, Ms. Alexander and Ms. Coleman were well-versed in everything from pupation to egg collection!

Thanks to all of the staff from WA Department of Corrections and MCCCW who work tirelessly to coordinate this program. And of course, we wouldn’t be here without support from the Oregon Zoo and Washington Department of Fish & Wildlife. It means a lot to have zookeepers and biologists coming to MCCCW and giving incarcerated technicians the confidence to work with this fragile and beautiful species.

Take a look at these photo highlights from the past few months.

Taylor’s checkerspot caterpillars in their newly-formed cocoons. They remain in this state for up to three weeks and then emerge as butterflies (also known as “eclosion”).

After wiggling free of their cocoons, two adult butterflies dry their wings. It can take several hours after eclosion before they are ready to fly.

Cynthia Fetterly searches for butterfly eggs. She has to check every inch of the plant and down in the rocks at its base. It’s a tedious but crucial task.

This female just laid a fresh cluster of eggs (the tiny yellow orbs on the leaf to her left).

All adult checkerspots must be weighed and measured. Notice how this technician grasps the butterfly with the sides of her fingers, avoiding harm to its wings.

Jessica Stevens keeps a watchful eye over adult breeding tents.

Mottled sunlight and a warm breeze are a checkerspot’s ideal conditions.

The adult life stage is a critical period in the captive rearing program. Technicians conduct dozens of breeding introductions each day, keeping track of each individual’s “matriline” in order to maintain genetic diversity.

Breeding Taylor’s checkerspot takes patience. After hours of waiting and adjusting environmental conditions, these two finally decided to mate.

It’s hard to deny the charm of the Taylor’s checkerspot butterfly. We extend our gratitude to the technicians at MCCCW who continue to prove that incarcerated people can make a difference in conserving biodiversity.

 

 

 

Taylor’s checkerspot wake up and release

Washington’s winter was exceptionally cold and wet this year, posing unique challenges for SPP’s Taylor’s checkerspot rearing program. After a deceptive warm spell, the butterfly technicians at Mission Creek Corrections Center for Women (MCCCW) brought the caterpillars out of winter diapause only to find that spring was yet to come! Temperatures plummeted and constant rainfall postponed the larval release that typically follows within a few weeks of wake up. But in spite of this delay, technicians patiently fed and nurtured over 3,000 hungry caterpillars as we waited for weather to improve.

(Left to right) Jessica Stevens, Cynthia Fetterly, and Susan Christopher rest after a long day of counting, sorting, and feeding caterpillars. The shelves behind them house over 3,000 Taylor’s checkerspot larvae!

Everyone (including the caterpillars) thought it was time for spring. But winter returned with additional snowfall at the MCCCW rearing facility.

WDFW biologist Mary Linders carefully releases Taylor’s checkerspot larvae onto their host plant.

When environmental conditions finally improved, SPP transported the caterpillars to field sites for release. Our partners at Washington Department of Fish and Wildlife (WDFW) were happy to see healthy and active larvae crawling about in the sunny weather. Sadly, the women from MCCCW were unable to attend the release this year, but their efforts in the lab were recognized as critical in transitioning these larvae from captivity to the wild.

In all, about 2,500 Taylor’s checkerspot larvae made it out to Salish lowland prairie reintroduction sites where they continue to support the recovery of this endangered species and their habitat.
