This was probably rose sawfly which can be greenish or yellow in colour. It is unusual and generally does not appear in the same place two years running.
There was no point in cutting down the bushes, but they will sprout again. The foliage may have turned yellow for other reasons, such as rose blackspot disease.
If there is another attack, use a caterpillar spray, or a multipurpose rose spray.
