Castilian eggar

or it might be Pale Oak Eggar, you need to kill it and dissect it to look at its genitalia to be sure. I'll happily remain in ignorence!

Another nice moth, I have heard of an oak eggar but not a castilian eggar. I wonder if you can look at a couple of my moth shots that i have not been able to identify. http://365project.org/oldjosh/365/2015-09-03 http://365project.org/oldjosh/additional/2015-08-16 thanks

@oldjosh Yes they are related I think. Your two moths are Mother of pearl and Yellow Shell.
