during the larva state, losing by this metamorphosis the scaly 

 coverings of the head and of all the exterior parts. They pass 

 into the pupa state, are furnished with legs and wings, and have 

 the thorax provided with dainty plumes, which probably assist in 

 the action of respiration. This pupa is very active and quick in 

 its movements in the water. When the moment comes for its 

 last metamorphosis, it throws off its feathery covering in much the 

 same manner as the gnat.

Fig. 32 represents Tipula oleracea in the different stages of 

 larva, pupa, and perfect insect. 



Other species of small Tipulce have aquatic larvae very similar 

 to those which we have described. Reaumur remarked that each 

 of these worms is lodged in a thick mass, convex at the top, formed 

 of a transparent and adhesive white jelly. As for the larvae of the 

 larger Tipulce, they are not aquatic, but are of different habits, 

 and live under the ground, all soil which is not frequently turned 

 is suitable to them, but they are to be found especially in low damp 

 meadows.
