Brown Argus and Common Blue butterfly are tricky when they have the wings folded and at that stage it all comes down to spots....
We have both species at Rainham and Pete Jackson has very kindly made up this very helpful aid for all of us to use!
Great stuff!

I'm impressed!However did he get those butterflies to sit still while he joined the dots?
