Is it a bird is it a plane?!

Hello my blippy buddy's! Welcome to another day on planet earth!
Today, me and my sister Nina decided to move the old TV cabinet into the place of the current one. Mums been meaning to do it for years. It was a hefty old job. We did find a few treasures though! Including a newspaper from 1966, and lots of things from my mum's childhood!
Just when we'd finished we heard the distinct sound of a helicopters rota-blades. Or so we thought. Somehow we'd accidentally found a dragonfly in the conservatory! The rota-blade noise was infact it's wings flapping against the wall! It was that loud! When we instantly got it out, we examined it at a closer angle. and just look at its body!
