THEM PRAYING MANTODAE
Just winging on your region, you were probably hit by the casual and common
Mantis Religiosa, the European Mantid.

If it fell from above it was most likely a male. Females (above is a female) cannot fly because their body mass is too large due to their reproductive organs and systems that allow the creation of their egg sack. They do have wings, but use them only for
defensive purposes. To appear larger, females bring their forearms up high and flair their wings whilst making an irritating hissing noise.
Now I'm going to take a guess you didn't piss him/her off, since they can give you a nasty pinch with their incredibly strong forearms.
Males, however, can fly, and use special flying tactics to avoid birds and bats. These little bugs are pretty damn awesome.
I hope you don't mind me explaining all this stuff, I used to breed mantises before I got my Gecko. I know
Mantis Religiosa from head to toe. :)
