I thought of you the other night as I was reading my novel; one of the main characters in a magical world created a flying frog to give his mother (who often had to work in swamps :-) so it could go after mosquitoes, LOL. It can "swoop" and dive/turn, etc. and has the long tongue so the mosquitoes didn't have a prayer. It's not "alive" but not mechanical either, doesn't have a motor or anything that can wear down, it helps the person deploying it, works around the "campsite" there to keep down the biting/stinging bugs. It sounds so helpful and lovely.
