Back home; and here's an example of the grey/brown phenomenon I chat about below. I think this is a Dusky Brocade but there are a number of contenders for moths like this, including one which is appropriately called the Confused Moth. You have to have patience. But the patterns on the wings are delicate and lovely, and as I think you can see from my pic, form excellent camouflage. You need this if you are a moth.
