A pupa has hatched!

I collected 4 pupa from my back garden in the spring whilst I was digging bedding room for bedding plants.
Over the last week or so they have got alot darker and this lovely Bright-line Brown-eye greeted me after work today.
I was half expecting it to be a Heart & Dart, but pleasantly it wasn't.
1 down 3 to go.....
