   Gordon Hart writes:  I have attached a photo of a nice geometrid moth that has been inside our greenhouse for about a week. I thought the brown colouring was a bit unusual.

    Jeremy Tatum replies:  Yes, this is a nice colour variety (which I haven’t seen) of the Barberry Geometer.  The foodplant of the caterpillar is usually listed as Barberry, although here in Victoria I have found it on Mahonia, which is in the same botanical family.
