The biggest swallowtail caterpillar has found my Dwarf Fernleaf dill, which should make it even fatter. Hopefully it leaves enough blossoms to harvest seeds! The dwarf dill wasn't a great sprouter so I'd really like to start next year with better-adapted seeds.
The Dukat dill has 2 smaller swallowtails on it, and they are slowly munching what's left. Luckily I am starting to harvest seed heads from it!
