Earwigs have what is known as an incomplete metamorphosis. They have three life cycle stages. Egg, nymph and adult. In this group of insects the young look similar to but smaller than the adults.
I have begun collecting earwigs for the chooks already but I always check which ones I'm catching!
They are known to eat soft-bodies caterpillars, the main one in my garden is the larvae of the codling moth which attacks the fruit of my Apple and Pear trees.
I have seen quite a number of these out in the orchard where they are protected, from the chooks, by large rocks!
If I were to set out traps of oil to catch earwigs, as is often suggested, I could be guilty of murdering these helpful creatures...and that is not something I intend to do!
