Heard a loud buzzing in the living room and this colourful character was climbing up the window. My apologies for the low quality photos, but I had to catch the creature somehow without harming it and the only thing to hand was a marmalade jar due to be washed before recycling.

Size: approx. 1.5 to 2 inches long

Is this insect safe to release back into nature?
