Glassberg’s A Swift Guide to Butterflies of North America cites our large, bright yellow Cloudless Sulphur as the “most common Phoebis.” I think that Jeffrey is right. At this moment, September 18th, we have as many as 15 of them flying in our 303 Garden (20 of them?).
They’re a joy to see, flying in shade or 98F sun, moving from our native flowers to our Tithonia (Mexican Sunflower) or Giant Zinnias. They are mostly kind, tolerating the presence of camera lens.
We notice that aren’t much shared here and on Facebook and other sites. That’s not the way it ought to be, for they are numerous, polite and pretty.
This male was seen on Pickerelweed blooms in a pond at Harris Neck National Wildlife Refuge, near the Georgia (USA) coast. Our boots came from there soaked, but no alligators bothered us. Don’t know who the much smaller butterfly was at the bottom left of the pickerelweed flowerstalk?
