Look Out for Swallowtail Caterpillars

Caterpillars of the Eurasian Swallowtail Papilio machaon (Fr. Machaon) can be observed on their food plants in September. They are busy fattening themselves up before winter, which they will spend as chrysalises, having wrapped themselves up before the cold weather hits.

They will leave their food plant and move to a sturdy upright stem where they will attach themselves and make a chrysalis. Depending on the surrounding vegetation the chrysalis could be green or brown, to blend in.

And they can even be found munching on fresh, domesticated carrot tops in our potager.... and the leaves of celeriac!

Yes, lots of gardeners find them munching on the garden carrots.
