I took this a few days ago:



I looked a pics on this site of common blue and noticed that on this one, there was only two white marks on hindwing underside. On pics here, there is two black marks inside white marks and the number of spots on hindwings vary. What is this?

Looks like a minor aberration to me Dave!
