I was so happy today to see a black swallowtail butterfly in the veg garden, visiting some of the small volunteer dill plants -- maybe laying eggs? Quite a few years ago we had a good population of the swallowtails and their cats -- that's when I started letting dill go pretty crazy in the garden; for the past few years, it's been a rare sighting (I think since the bad winter of 2013-2014). Last year I did find a couple of the caterpillars, so I hope this is signaling a comeback!
