The children spotted this attached to the railings as part of our school field/hedge. They asked me what would emerge and I suggested we ask for help.
No identification made yet.
No interactions present.
Rather out of foucus but possibly a lepidopteran pupa. If you retain it (in a jam jar / magazine pot with a few twigs for whatever emerges to climb on) you might find out exactly what species as I doubt we will get to species level ID here.
