The process of tissue-destruction is known as 'histolysis'; the rebuilding process is called 'histogenesis.'
Considerable difference of opinion has existed as to factors causing histolysis, and for a summary of the conflicting or complementary theories, the reader is referred to the work of L.F. Henneguy (1904, pp. 677-684).
The last larval cuticle, instead of being as usual worked off and cast, after separation from the underlying structures, becomes hard and firm, forming a protective case (_puparium_) within which by the processes of histolysis and histogenesis already described the organs of the pupa and imago are built up.
In the histolysis of the two-winged flies, wandering amoeboid cells -- like the white corpuscles or leucocytes of vertebrate blood -- have been observed destroying the larval tissues that need to be broken down, as they destroy invading micro-organisms in the body.
In this condition it remains for seventeen days, when it throws off its embryonal membrane, and becomes detached from the shell.] [Footnote 24: It is a suggestive fact that these deciduous forms give way through histolysis to true larval forms, just as in some flies
