April and May on Elcocharis ^Jalustris, feeding in the stems, 

 moving from stem to stem, hollowing each one out and 

 stunting its growth, frequently causing the stems to turn 

 brown, and gradually decay. 



This species inhabits the wettest marshes — places where 

 one's feet are constantly soaking in water when catching it.
