I noticed a kind of tent on the end of a sprig of lavender. When I opened it up I found this black larva. I have no idea what it is. The only insects I generally find on lavender is are rosemary beetle, but this seems to be something different. The remains of the tent are still attached. Once out of its tent it seemed to get bigger but maybe I am just imagining that. It is active when disturbed - quite difficult to photograph.
