Oh my lord those damn caterpillars - I have suffered this year with every kind of caterpillar you can name. Prevention is better than the cure and I have learnt this the hard way and will be netting against butterflies/ moths next year. However this does not help in the present. Remove all the eggs you find - each one will turn into a munching machine and descimate your brocolli before your have time to blink.
One day I had beautiful purple sproating brocolli the next day I came out to find caterpillars on every square inch of each plant - it was like something out of an Alien film. I had very little bother from slugs/ snails on my broccoli so it I would say that the odds on favourite is the caterpillar. Remove remove remove!
