Butterfly Rearing Commences at Mission Creek

At long last, the wait is over. After almost a year of preparation, the butterflies have finally arrived! Inmate technicians at Mission Creek Corrections Center for Women (MCCCW) have been caring for painted lady larva for almost three weeks now, and over the weekend they got to watch their first butterflies emerge from their chrysalid.

The painted ladies are being reared as a training surrogate for the endangered Taylor’s checkerspot, which inmates will begin to work with next February. These training butterflies were chosen for their relative hardiness and fast life cycle, which will allow the inmates to go through several complete revolutions before graduating to the much more delicate Taylor’s checkerspot. So far the inmates involved have surpassed expectations in every way.

As the final phases of greenhouse construction were being completed, the student intern on the project, Dennis Aubrey, began rearing painted ladies at the Sustainable Prisons Project (SPP) lab on The Evergreen State College (TESC) campus. This was done to work out the fine details of adapting the Taylor’s checkerspot rearing protocol for use with the painted ladies, and to prepare for training the inmates at the facility. Following this, 200 painted lady eggs were ordered and delivered to MCCCW, where eager inmate technicians began learning how to care for these delicate insects.  Working with butterflies in the SPP lab approximately two weeks ahead of the ones at MCCCW was incomparably helpful in training the inmates effectively.

From the time they began, the inmates have been taking very detailed carefully drawn notes, and have been tending to their charges with the patient meticulous care that makes all the difference in rearing projects such as this. At SPP’s frog project at Cedar Creek Corrections Center, the large amount of time inmates dedicate to caring for the endangered Oregon spotted frogs has led to the largest specimens raised at any institution. Last week, when Dennis visited Mission Creek to check on the inmates’ progress, he couldn’t help but notice that the painted lady chrysalids were significantly larger than he was able to produce in the SPP lab. Whether that’s a factor of the light and beneficial conditions in the greenhouse, or is directly attributable to the increased daily care, it’s hard to say. Either way, it’s a great sign of things to come for the future success of the project.
