I found an interesting site today http://ukwaspwatch.co.uk/

Looks like they are trying to create a map of wasp sightings, stings and nests, although it needs a lot more people to add to it before there is enough meaningful information. What would be good if this was expanded to the entire world and included many different types of bugs.

Still it’s a start and if you live in the UK, then please add your sightings.
