Star Wars Garden Gnome Likewise Many Cats On The Fennel?

I counted nineteen caterpillars - eastern dark swallowtails, I intend - on the bronze fennel (Foeniculum vulgare 'Purpureum'). You tin hand the axe come across thirteen or xiv of them inwards the photograph below if you lot await carefully...

Here's a close-up to brand things easier...

How many caterpillars tin hand the axe move on a unmarried fennel plant? I worry nigh whether these cats volition bring plenty to eat, merely since I solely bring the 1 fennel found growing inwards my garden (I straight sowed a parcel of seeds too solely 1 found grew to maturity), I don't intend I bring whatever options to relocate whatever of the cats.

Hopefully they'll all larn far to maturity too volition live able to pupate successfully! So far, there's withal plenty of foliage, merely in that place are every bit good lots of hungry caterpillars!
