Wow,never seen that before. How crushing. Can’t tell whether it’s compost or droppings in the area near the stem. I know of various moth species who spin webs but I can’t see anything has been nibbled. The other classic is red spider mite that makes webs, but as I haven’t got a polytunnel or greenhouse I’ve never seen it ‘in the flesh’. Hopefully someone else will know exactly what it is.
Good luck
