UPDATE: new observations instars 4 and 5 added

I spotted these small, remarkably coloured and humped caterpillars in Fennel (Foeniculum vulgare). In total eight specimen smaller than 1 cm were positioned low to the ground in the plant. These caterpillars were new for me and turn out to be Swallowtails (Papilio machaon). A new garden species!

Unfortunately I missed the ovipositioning adult. Very nice to be able to see these larvae developing. Hopefully I’ll be able to observe some butterflies later on.
