Abstract

Tipula paludosa spends increasing periods of time in a pharate condition with each succeeding molt. The pupa is entirely pharate since larval–pupal ecdysis coincides with pupal–adult apolysis, and the larger part of the adult instar is also spent in a pharate condition. The fact that the instar usually referred to as the pupa is actually a pharate adult should be clearly understood by physiologists, ethologists, and ecologists.

Résumé

Tipula paludosa passe de plus en plus de temps à l'état pharate à chaque mue successive. La pupe est pharate pour toute sa durée étant donné que l'ecdysis larve-pupe coïncide avec l'apolyse pupe-adulte, et une partie importante du stade adulte est également passée à l'état pharate. Le fait que le stade appelé pupe est en fait un adulte pharate devrait être clairement compris par les physiologistes, éthologistes, et écologistes.
