Camouflage expert! The Small White caterpillar

I am in a bit of a dilemma. The other day I told a friend I had been squashing caterpillars of the Small White butterfly which were wreaking havoc amongst my Sweet Rocket seedlings.

Carnage!

She kindly reminded me that caterpillars turn into butterflies and as I want to attract butterflies into the garden I shouldn’t be killing their children! And, if there is a shortage of butterflies next year, it will be my own fault. Point taken!
