I found these pods '?' on a lavender stem while taking care of some spring pruning last week. I've lived with lavender plants long enough to know that these aren't seeds.

I didn't clip the stem because I need to know a few things first:
--What are they, (or what will they become?)
--What will they eat -- plants, or the bugs that eat plants?
--Will they become pests?

In short, should I keep them or clip the stem and get rid of them before they have a chance to become a problem?
