I have been enchanted a few times this spring by the presence of this lovely visitor, who chilled obligingly in the hydrangeas while I ran and got my camera:
Today I ran into a passerby taking some pictures of flowers in the front border, and she pointed out this critter in the rue:
Upon closer inspection there were at least half a dozen of them munching away in there. A bit of googling reveals that (a) these are the caterpillars of the lovely visitor above, namely an old world swallowtail, and (b) they looooove rue. Who knew?? I bought the stuff because I liked the foliage. Not sure whether the butterfly's presence explains the caterpillars or the other way around, but either way, I think I need a couple more of those plants!
