What causes fly strike in sheep?

In England, blowfly strike is mainly caused by the maggots of the green bottle fly (Lucilia sericata), black bottle fly (Phormia terraenovae) and blue bottle fly (Calliphora erythrocephala); the flies are attracted by the sheep's fleece, wounds, footrot, soiled fleeces and even dead sheep.
