Our summer fundraiser has arrived, and we need your help!
We depend on donations to keep Butterflies and Moths of North America online and free. If everyone who uses this resource makes a donation, we could cover our ongoing costs, develop new features, upgrade the system, and maybe even remove those pesky ads. Please make a one-time or recurring donation to show your support for this valuable source of information. Thank you!
Observation notes: Weather: Partly cloudy and 50 degrees. Notes: This was the only Moss' Elfin I saw along the Arthur's Rock Trail; it was originally perched within inches of a Sheridan's Green Hairstreak (none of which I was able to capture and/or photograph on the 28th). Also, according to iNaturalist, the Moss' Elfin is considered vulnerable in Colorado. To your knowledge, is this true?

Coordinator notes: In my estimation, there is no threat to Schryver's Elfin. Many of the places it occurs in the Front Range are protected open space and it often occurs where there is little possibility for development so it should remain secure. I've found larvae on Sedum (same host Parnassius uses) and reared them. Mike
