Colin in Essex asked:
I found a couple of beetles over an inch long and the shell looked like a withered acorn. The wing span was nearly two inches. The antennae looked like they had a pair of false eyelashes on the end.
A beetle with eyelashes on the end is like a scarab beetle or a chafer beetle. The technical name is Lamellicorn beetles. They use the antennae for picking up pheromones, scents and chemicals and things. So it could be some kind of chafer beetle, a rosechafer or something like that. It's also a good idea to look for a picture on the internet, as you'll find out for certain what it is you have found.
