The female Phrjganidae like the Ephemeridae produce their 

 eggs in double series : the larvae live upon those of aquatic 

 insects and the leaves of water plants : in this state the Limne- 

 phili form cases (from whence they are called Caddis or case- 

 worms) constructed of various materials, with a silken lining 

 impervious to the water and open at both ends ; but previous 

 to becoming pupie a grating is placed at each end to prevent 

 other animals from molesting and destroying them, and at the 

 same time for admitting the water. The larvae are furnished 

 with fleshy tubercles on the following segment to the pectoral 

 feet, which no doubt are to prevent them from being drawn 

 out of the case in the event of any resistance, as they walk along 

 in the water. There seems to be a state in the Phryganidae 

 somewhat analogous to that of the Ephemeridae, for at first 

 the pupa is quiescent, but when it is about to become an Imago 

 it cuts through the grating of the case before alluded to, rises 

 to the surface of the water, crawls upon some plant, the an- 

 tennae and legs being free, excepting the hinder pair, and there 

 it leaves the exuvia.

" PhryganejK," says Stewart in his Elements of Nat. Hist., 

 " are the favourite food of Swallows, and the larvai are used 

 by fishermen for bait : in some parts of Holland they are so 

 abundant, as to be used for manure." 



The Plant is Stratiotes aloides (Fresh- water Soldier).
