Abstract

Very little, if any, work has been done on the thorax musculature in · the larvae stage of insects. The work that has been done has been confined mostly to the muscles of the abdominal region. From this work it has been found that extraordinary differences in muscle pattern occur often between larvae and adult stages of the same species. Since the muscles of all insects are more or less comparatively the same, what is true of one .will be generally true of another. There may be slight variations found between the abdominal segments and head segments but these differences can in most cases be contributed to the differences in function between the two regions. Since the processes of contraction and retraction are similar in the abdominal and head regions the muscles which are used for this action would generally have similar origin and insertion.
