Cloudless Sulphur (Phoebis sennae)
Oh my! That's my fav butterfly!!!! We've had a few visit our gardens this year...but never more than one at a time :(
I have planted a couple of Cassia herbecarpa plants and hope they will really bring them in droves next year when the plants are bigger. Here's a pic of them...
Thanks for posting the pic...it made my day!!! :)
They do love the cassia - you might want to try some cassia alata because they grow really fast and will be big the first year for them.
