We have some "guests" staying in our garden. They seem to be enjoying our fennel plant. For "pests" I might try to get rid of them, but who could do such a thing to baby butterflies?
I first spotted the pair (I would guess they are probably brothers.) on the 4th, while we were outside in the evening. Two days have passed and they have just about doubled in size!
I checked on the web and I am pretty sure we have the caterpillars of Anise Swallowtail butterflies. The pictures pretty well match, we have seen adults that match the pics online AND...well...they are eating anise.
