That’s a wrap on the 2025/2026 butterfly rearing season! All of the Behren’s silverspot butterflies have been released to boost the endangered population in Mendocino. Final numbers will be shared soon.
We released our last butterflies a couple weeks ago, bringing the 2025-26 season to a close. What wasn’t on my bingo card was not being able to find new Behrens’ Silverspot butterflies to lay eggs for the 2026-27 season. It’s been a cold foggy summer, so the flight season may have ended early. Or the butterflies may have been eaten by an unusually large population of migratory dragonflies in the area. Whatever the reason, we have only been able to capture one female Behrens’ Silverspot. She is one of the captive reared butterflies we recently released, and may not have been mated because her eggs are not fertile.
Last week, I joined the capture team in the field. As I chased what I hoped was a Behrens’ Silverspot over uneven ground, I tripped and fell…twice. Each time, I resighted the butterfly, picked myself up, and kept running. Ultimately it got away, but I see this as an analogy for the coming year. I’ve got to pick myself up and keep my eye on the prize. And use creativity and resourcefulness to pursue different strategies for helping the Behrens’ Silverspot, even if I can’t rear caterpillars.
Update on the final number of butterflies released coming soon!
