" Inhabits the banks of rivers throughout the summer, gliding 

 among the wet gravel, its silky down protecting it from the wet. It 

 takes flight readily, even off" the surface of water. The yellowish 

 larvae and pupae are found in the same situation, leaping like the per- 

 fect insect. In its habits it most resembles the Saldce, but shuns 

 the light more than they do." {Tlalidmj, 1. c.)
