Wasps

During our walk today we sat down on a bench to rest. But I was on my feet again faster than quick. Wasps crawled on the bench, not just one but several.
The wasps also flew away, except for one. And I was brave .... or stupid because I am allergic ..... and dared to take a photo quickly. 
We did not sit on the bench again, because the wasps came back and flew under the bench, in a cavity between the bench and the cement base, their nest was probably there.
