268 THE DRY-FLY MAN'S HANDBOOK 



PHRYGANEID^ 

 The following insects of this family are likely to be 

 found and are fairly plentiful. Advisedly, I omit 

 those which are comparatively rare, because they are 

 of little or no importance to the fisherman. 



This is the largest of the British Trichoptera. 



It is very similar to P. striata, 

 Phryganea grandis. but is a trifle larger and the 



body paler. Experts differ- 

 Large red sedge. entiate the male from the male 



of P. striata by the difference 

 in shape of the genitalia. It may for all practical 

 purposes be considered as identical with P. striata, 

 and both species are known by the popular name of 

 large red sedge, the female being the Murragh of 

 Irish lakes. 



„, . The male is figured in Plate 



Phryganea striata. vvvTT 



Mosely has found this on Lough Arrow in Ireland. 

 The fly is a smaller insect 



Phryganea varia. than either of the two afore- 



mentioned species ; has grey 



wings strongly marked with dark patches. It is a 



striking and handsome-looking insect. 



Phryganea obsoleta, another species, is larger than 

 P. varia, but not so large as 



Phryganea obsoleta. P. grandis or P. striata. It is 



found plentifully on the lakes 



in the neighbourhood of Blaenau-Festiniog in Wales, 



and no doubt elsewhere.
