Phryganeae, Ephemerae, Sialidae, Perlidae; so you have no excuse for telling -- as not only Cockneys, but really good sportsmen who write on fishing, have done -- such fibs as that the green drake comes out of a caddis-bait, or giving such vague generalities as, 'this fly comes from a water-larva.'
