DAY-FLY. 



PHRYGANEA. 



Plate 7. 



The Mouth is oblong, and without Teeth. 



There are no Feelers* 



There are two large Studs upon the Head, juft above the eyes. 



The Wings are carry 'd {landing upwards, and are unequal in fize. 



The Tail has briftles annex'd to it. 



The Day-Flies are an inoffenfive race ; born to pafs thro' their little 

 ftage of being, the prey to a thoufand enemies; but hurtful to no crea- 

 ture: they live about waters, in which they breed; and in their Fly ftate 

 have fo mort a term, that it has been the fubject of feparate hiflories, 

 by Naturalifts, and Emblems for moral writers. The name, Day- 

 Fly, arifes from their living in that ftate but one day : but in many 

 of the fpecies, even that period is much longer than is allowed. 



The particular kind firll to be figured and defcribed in this place, 

 never burfts from its Reptile ftate, till about fix o'clock in a fum- 



mer evening ; and never lives to fee the next fun rife.

Five hours complete its little fpan of life ; in the which time, if 

 it efcape the Fiih, the Dragon- Flies, and Reed Sparrows, (for all are 

 after it) it copulates with the Male ; depofits its impregnated eggs 

 in the waters ; and dies before the cold of midnight. 



But 'tis not that thefe hours are all it lives ; 'tis in thefe only it 

 enjoys the air : but the Worm hatched from the egg of this Fly lives, 

 and feeds heartily in the waters, enjoying a much longer date* and 

 that in more fecurity ; for it covers its tender frame with a motley 

 cafe of its own conftructing j and gormandizes unfufpecled, and un- 

 feeni for one, or fometimes nearly for two years.
