I had green caterpillars eating holes in the leaves of my broccoli and brussell sprouts. Since they are all the same species, perhaps that is what you have? They blended in really well and were tough to spot when they were small, but became more obvious as they grew. I usually found them on the inner leaves. I just picked them off manually and have seen no new caterpillars or leaf damage for weeks.

I've been having the same problem with my cauliflower and broccoli leaves. They're being eaten by small worms..i think they're tiny caterpillars. There are several of them on every leaf. What can I do to get rid of these caterpillars? Thanx..
