Our windows have very red trim so when I spotted something green on one of them I had to investigate.
It's a very rare insect that chose to visit my house.
A walking stick.
I wondered how it got there but I guess it has wings.
On any part of a plant it would have been camouflaged but on my window - not.
It didn't stay very long or else something got it.
I only remember seeing one once before many years ago and not around here.
