I have foamy looking stuff on the tops of my Rosemary branches. What is it?

I've noticed an abundance of ladybug larvae in that portion of the garden, and a lot of ladybugs in my backyard (not that I'm complaining of too many ladybugs in my garden)

Update:

Was it a wet foamy sticky substance or powdery? On my Rosemary it is white wet and foamy. It does not seem to be hurting my bush and it is the only bush in my herb garden with it.

    It is the pupae stage of many insects. It is like a cocoon. The insect will emerge as an adult from this foam.

    It sound like leaf hopper nymphs aka spit bugs. Just hit with the sprayer hose and wash them off.

  • maybe aphids? cant tell without a picture. Use a insect soap. Two or three applications should clear it.
