Plebejus acmon

Observation date: September 12, 2019

Coordinator notes: I have to accept this as a very aberrant Acmon Blue BUT it might be a Lotus Blue, but without a specific locality or habitat information or seeing a series, I cannot confirm that claim. If you can provide such information you could resubmit. I have seen both Acmon and Lupine Blues have orange go up forewings, but not so brightly as yours.-Ken Davenport
