Gellocks and Slatecutters

This is an earwig, but in Ulster-Scots its a gellock. Below is a woodlouse, usually known as a 'slater' across pretty much all of Ulster. But for me in the tiny sliver of the Ards Peninsula we always called it a 'slatecutter'. A Twitter friend who is researching these wee beasties directed me to the fascinating 'socchetre' etymology underneath.
