John and Fons, very interesting images for early morning and first cup of coffee
John , what is that shape being pointed at. My only experience with be catchers here is when a hive starts growing under my eaves I call the local Beeman who comes and captures the hive. Sort of like the local Snakeman
who gets the call when I have a Cobra or Russell's Viper
Fons, I viewed that second image, without reading glasses, on my mobile and did not have a clue as to what I was seeing. Thought it was Apes in a cage
. Cool image.
