Oh dear, I appear to have caused a bit of a rift between you - I'm so sorry .

As I live in the UK I'm sure there aren't that many 'nasty' insects about, and our neighbourhood don't use pesticides in abundance in the garden thats why we have so many wild frogs, newts, dragon flies etc etc in our garden.

Thankyou for your comments, I will try some moths when the warmer evenings arrive, but maybe not caterpillars.
