Common or Lemon Migrant

Thanks cole & thanks Martin for your help. I was a little confused with this one.

Please note these two links;

These have contradictory gender assignments.
The second by Don Herbison-Evans is correct, the female has more black spots.

The lower one seems to be a female C. pomona. These are common in your area. The male is plainer yellow but hard to see clearly. I'll go with cole. http://en.wikipedia.org/wiki/File:Catops...

Thanks Hanno Shalby :)
