Wakeham

Well that didn't go to plan. The idea was to carry on sorting the back garden out and then take some photos of anything of interest. All was going well until a shower moved in, and then the weather went down hill rapidly, with lots of cloud and strong gusts of wind.

There was no sign of the male Azure Damselfly, though there were several Semaphore Flies (Poecilobothrus nobilitatus) on the lily pads in the "Bath" Pond.

And the only highlight was a Common Buzzard being mobbed by one of the local Herring Gulls as it passed overhead.

Semaphore Fly

No photos today but below is a small piece on Semaphore Flies.
