DIPT ERA 61 



which are generally green, are found in 

 towns. 



Blue-bottle 



Body. Fine dark blue chenille or dark 

 blue Berlin wool, ribbed with silver tinsel. 

 (I have found the fly very successful when 

 ribbed with light blue silk as well as the 

 tinsel.) 



Hackle. Black. 



Wings. Transparent wing feather of 

 starling. 



Hook. Nos. 2 4, new size. (No. 3 best 

 all round.) 



Green-bottle 



Body. Bright green peacock herle, rib- 

 bed with silver tinsel. 



Hackle, Wings and Hook. Same as Blue- 

 bottle. (Illustrated Plate II.) 



HOUSE-FLY 



There are many small Diptera which 

 frequent the water side, which to the or- 

 dinary eye are apparently House-flies. 

 They resemble them so closely, in fact, 

 that many could not be discriminated from 

 them except by an entomologist.
