Found this morning on top of my car which was put into a dry dusty garage overnight, all very dead!
About 20 corpses were fairly evenly distributed over the roof with just one on the bonnet.
At a normal distance they appeared dull grey rather like dead woodlice. They are small and I wondered if they were small seeds with a feathering, but on looking closely I could see clusters of legs! I don't think this the woodworm beetle, but it might be some exotic cousin. The common woodworm it seems has hefty wing cases Have a look at - -
Thank you both for understanding and getting the commands right!.
lotvic - you showed how to use Photobucket.
Mr Mistoffelees - you gave me a potentially more successful website.
I won't tick this until if or when I receive some ideas from the Nat.History site, in which case I will add it to this thread for general interest. I wouldn't like to meet one of these scaled up by say x10
Had a reply on the Natural History Museum site and....... the answer quoted here
"They're water boatmen. Unfortunately, they're mistaking the reflections of your car roof for water and so they think they're diving in to a pond. The long flattened back legs are excellent for powerful swimming strokes."
I would never have come close with that answer, but finding facts to fit a theory...
Close to sunset so a very low angle with sharp bright lights from certain angles, and a small garden pond 30 yds away.
The size of the little bodies compared to the length and strength of their legs would unfold to the normal pond skimming shape of little substance.
