Yesterday evening I was talking outside our offices at dusk. Although not completely dark the sun was well down, gradually I registered the call of a bee-eater as it approached, passed overhead and moved off.  To me this seemed unusual but bee-eater is not a frequent visitor to my home shores so I am not that aware of their nocturnal habits.
One definate night flyer was this moth that I found in our building in the morning.  Up close it has a very strange marking on its back. I will keep my eye out for any other species of moth.
