Josephine, the Queens have been here and laid eggs. Some eggs & caterpillars on A. curassavica, but I actually found 2 caterpillars on the Funastrum cynanchoides vines. So the Queens like it as a host plant. I did notice when cutting vine to bring in for the caterpillars, it has LOTS of the white latex sap! I have to be real careful, because I did have a problem last year because of milkweed sap. Somehow a little of it must have gotten in my eye and it caused a problem with my cornea. Turned out okay, however, after I saw my eye doctor. Anyway, the two cats from the F. cynanchoides vines both pupated. The vines bloomed last month.
