Thank you very much for the dragonfly ID, it looks spot on when comparing with images online and it should have crossed my mind, given the county I am in.
I don't think the birds changed the requirement for revision but the temptation was too much for me. If the possible lifers were all LBJs or just proving elusive, resisting would of been a lot easier. I possibly lost a grade in a subject or two but they're only mocks, not the actual GCSE exams, although mocks are still very important as colleges etc. look at the results from them. What a naughty boy I am! Thanks for the congrats on my lifers.
