Skeletal Musculature in Larval Phases of the Beetle Epicauta Segmenta (Coleoptera, Meloidae) : Springer : 9789400996021 : 9400996020 : 19 Oct 2011 : This study, the first in an intended series of anatomical investigations of the blister beetles, was undertaken primarily for the purpose of determining the changes that occur in the skeletal musculature during postembryonic larval development. The species studied, Epicauta segmenta (Say), like others belong­ ing to the coleopterous family Meloidae, is characterized by hypermetamor­ phosis (SELANDER and WEDDLE, 1969). The egg develops into an active, well sclerotized larva that searches for grasshopper eggs, which, as in the case of all species of Epicauta, serve as the sole larval food. This triungulin phase of the larval stage, as it is called, is followed by the first grub phase (Fig. 1), during which the larva continues to feed and undergoes several molts. After feeding is completed the larva commonly enters a sessile, diapausing coarc
