I didn't see it but a largeish black dragonfly was seen in one of the
greenhouses the other day. It's not a type we've seen round here
before and it's thought 'he' was at the end of his life as the wings
were very tattered. I just hope the pond was discovered and eggs laid
by a female.

Probably one of these...
