Large insect!

This sculpture was in the community garden where the GG was working today.  Mainly weeding round gooseberry and currant bushes and mulching them with woodchip.  
Didn't find any babies, so perhaps they come from somewhere else?
On my return home I trimmed the ivy at the front of the house and cut the grass.  Seem to have a problem with my outside electric socket,  stopped working a couple of times.  Not having a lot of luck with anything electrical this week!
