Questions must be asked about Ladybirds.
This one here landed on the window and began to climb up the woodwork. Why?
The creature has wings so why not fly to the top rather than slowly struggle upwards on your feet, especially when every so often you fall back again?
Does he know where he is going? What is he looking for? Does he think the white painted woodwork on the window will feed him perhaps?
Some beasties may be colour blind I suppose but if so why do plants/flowers have such a variety of colour?
On another subject why do fly's come in the window and hover around the lampshade? Is it because it is er, cooler in the shade? Why not stay outside in the wind? Why fly in straight lines changing every so often to different directions? Don't they get dizzy? Bluebottles fly in desperate to get out again, why not fly's?
I have been working too hard, you can tell....
