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.
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.
