Cloudless Sulphur Butterfly

Cloudless Sulphur Butterfly at Blackwater National Wildlife Refuge, MD

One of the most focused nectarers, this Clouldless Sulphur is at work at Blackwater National Wildlife Refuge in Cambridge, Maryland.

She is large for a Sulphur butterfly and it is a bit startling to see this fly in with her not exactly straight path.

Phoebis sennae is said to range well into Pennsylvania. ?. I have … maybe, seen 2, fleetingly, in these last 12 years of field work in western Pennsylvania.

At Blackwater they are regularly seen. What a treat!
