Speyeria cybele

Hello everyone,

So as it gets near the end of the season for Speyeria cybele, they start to lay their eggs. I netted 3 today. I also bought 2 pots of Common Violet, their host. However, 1 started flapping on the floor and stopped flying. Now, it appears to be dead. I had another one do this but it seemed to recover. Does anyone have any experience with this? This has happened before with Speyeria spp. Can anyone explain it?

Thanks,

Ethan
