This “Challenge Skipper,” posted weeks ago, happily brought comment from several very authoritative experts. Unfortunately, definitive ID required review of another photo of the butterfly and there is no other photo. Butterflies can be very skittish. Multiple photographs are often not possible.
Challenge Skipper II reveals my difficulty with skippers. Those of you who choose to study butterflies in your university studies will surely have much less difficulty telling one grass skipper from another.
What we can share is that this little pretty is nectaring upon Black-eye Susan (Rudbeckia hirta) along a trail in Raccoon Creek State Park in southwestern Pennsylvania. Serious gardeners recognize that there are now dozens of hybridized Rudbeckia perennials available in the U.S..
My own experience is that Black-eye Susan wildflowers spend most of the critical morning hours without any butterfly visitors. Unexpectedly, there may be a burst of activity on these flowers, for very short periods of time. Then those butterflies, bees and flies will not be seen on these flowers for the rest of the morning. How do we explain this? Do Black-eye Susans produce nectar for brief periods of time?
Back to our skipper. I have seen more than 60 species of butterfly in this beautiful state park over some 12 years. I have seen a Goatweed Leafwing, an Orange-barred Sulphur and Compton Tortoiseshells.
This one was shot on the morning of July 13th. Please, if you are amongst the heavyweights in our growing audience, Comment on the correct name of this tiny beauty.
