Photos from 20 June.
I spotted that caterpillar in one of those little gardens/lawns around apartment buildings. The plant it was sitting on must be either dill or fennel (to my shame, I have trouble telling them apart). I can only hope the plant's owner(s) never saw the "visitor" because not everybody is a caterpillar lover like me. It was at least 5 cm (2 inches) long - the caterprillar and not the plant, LOL. Two people in a Bulgarian entomology group on Facebook tentatively identified it as a Old World Swallowtail,
Papilio machaon. I searched for images of larvaes of that species and the markings on most of them weren't quite the same, but
this one is pretty close.
I only returned to look for it tonight and it was no longer there; let's hope that it has survived and is in a safe place.
And here are the clouds over the new aprk that same evening just because I liked them, but Ithink they looked pinker "in person":
