her eggs gradually in a dark gelatinous string. As 

 the end of this string touches the water it swells up, 

 and the egg mass eventually assumes the form of a 

 cylinder of jelly, the end of which is firmly attached 

 to some fixed object close to the water's edge. The 

 larvae hatch out within three to six days, and then 

 follows a rapid succession of broods from the 

 beginning of spring to the late autumn, though such 

 larvae as are alive during the winter continue in the 

 larval and pupal stages until the following spring. 

 An interesting fact concerning the reproduction of 

 species in this genus is noted by Darwin, namely, 

 that pupae of either sex of certain species of 

 Ckzronomus produce larva; which finally develop 

 into males and females reproducing their species by 

 depositing eggs in the ordinary mariner."
