A large, long empty cocoon spotted in the grass. Prime contender is a moth quite common on these hills. Its large furry caterpillars overwinter undercover and then enjoy the best of the warm spring sunshine (other spring weathers are available), sitting around in a leisurely manner before pupating.
Presumably this is the case of an early emerger, neatly slit open at the tip (left side of photo).
