This fpecies is fometimes found on aquatic plants : they are ex- 

 ceedingly numerous in Kent, in the peafe and bean fields, during 

 the month of May: we have alfo found them on currant bufhes, and 

 not unfrequently on the fern. They fly well by means of their 

 wings, which are concealed beneath the wing-cafes.
