I know all animals, birds, insects etc have a purpose...they either eat or get eaten or they pollinate plants or munch on plant predators...everything sort of fits together nicely. So where do woodlice fit...and earwigs? Toads and frogs eat slugs though there is a dearth of toads in Ireland...St Patrick probably banished them along with the snakes for all I know...and frogs are't commonplace enough to dent the slug population because there are herons...who eat the frogs...
But who eats woodlice? Not those rather endearing little pill.woodlice who roll up into a neat ball when you look at them...not that sort...the other ones...the flat grey woodlice who breed like feckin' rabbits and lurk in their hundreds under any undisturbed plant pot where they dig away at the soil and make it all dusty...that sort of woodlice.
'Cos I don't like them much.
And earwigs...silly sort of a name for a silly sort of an insect really...they get all brave and waggle their antennae about but they don't seem to have much of a purpose to their being here apart from gathering under the flowerpots with the woodlice...
Something else which is about at the moment, which I suppose would be food for bats and birds, are those god-awful crane-flies that come in at night and bash themselves senseless against the lights and then drop like a stone onto your lap where they waggle their long skinny legs about frantically 'cos they invariably land upside down...then you have the choice of either squashing them on your book, Kindle or sewing or sort of flapping at them in the hope they'll fall on the floor and a dog will eat it...
Those sweet little pill woodlice were once used as a cure for headaches...you swallowed them...so they had a use.
