Staffordshire, United Kingdom

Greetings everyone
This year for the first time, I have succeeded in protecting my cabbages and cauliflowers from the Cabbage White Butterfly by growing them in a cage made of right plastic netting with openings of 12 mm. However all the plants have been attacked by something (see photos) any ideas and suggestions would be welcome.
NB Sorry I have put 1 photo in twice and can't get rid of it.
