I’d guess that the number of butterflies at the PGT is down by 90%. Even though their favorite nectar plants are in bloom right now there are very few butterflies around. I am seeing a lot of Liatris, Buttonbush, Coneflowers and Milkweeds flowering. Typically that is what tells me to grab my camera and go take pictures.
Instead of swarms of butterflies over the plants I’m seeing just an occasional single specimen; typically a Spicebush Swallowtail (Battus philenor) like you can see on this picture that I took after lunch today.
Some people have suggested the wet weather hurts them. I hope they recover soon!
