How fish feed on it

One of the few sedges that gives you an AFTERNOON rather than an evening, which makes it the answer on a summer day when everything else is waiting for dusk. Chalk and limestone rivers, from late spring into early autumn — and on those rivers, the medium-brown-sedge answer covers a good deal more than this one insect.
