AMERICAN TROUT-STREAM INSECTS 



branches of willows. It is a pretty little fly, dull 

 in color; and it is one that cannot be left out of an 

 April list of good flies. 



Ronalds describes two flies, the "jenny spinner" 

 and the "iron blue dun," which seem to correspond 

 with these last two flies, the soldier drake and the 

 sailor drake ; the sailor being captured six days after 

 the soldier. He says: "After two days the iron 

 blue changes to the jenny spinner." I can furnish 

 no proof that the sailor drake was transformed from 

 the soldier drake, though I captured many speci- 

 mens both at rest and on the wing. I should, how- 

 ever, much prefer to have them named in their class 

 as small blue and brown drakes, instead of duns and 

 spinners. 



No. 8. Redbug. This handsome little beetle is 

 exceedingly plentiful early in April on warm days. 

 It flies swiftly and is seen a great deal over the 

 water's surface; though on land it prefers sandy 

 places, from which I imagine it breeds from a land 

 creeper. In flight its appearance is very attrac- 

 tive, very much like the English artificial fly named 

 "marlow buzz." I saw several specimens floating 

 on the surface with wings outstretched; and I 

 should think that two imitations, one at rest, the 

 other in flight as seen skimming close to the surface, 

 would be an excellent April fly. The one I have 

 tied, copying the insect at rest, has been tested, and
