present in the larvae and absent in the pupae (R hy a c o phi 1 a); in other 

 groups (Polycentropodidae) the larvae do not have gills, but gills appear in 

 the pupae.

In the Integripalpia, the lateral line of the pupa is present on fewer 

 segments than in the larva; for example, in the Phryganeidae, the lateral line 

 of the larva begins on the 3rd segment but it begins on the 4th segment 

 of the pupa; in the Limnophilidae, the lateral line of the larva begins on the 

 3rd segment and in the pupa on the 5th; it begins on the 3rd segment in the 

 10 larva of Goeridae and on the 4th or 5th segment in the pupa. The lateral 

 line of the pupa bears a fringe of dense and long setae which is well 

 developed in many species. 



In pupae of Integripalpia, enclosed in narrow tubes, the dorsal side of the 

 1st abdominal segment bears 1 or 2 processes with spines or crotchets
