TLDR
The spatial and temporal compartmentalization of endocrine interactions has produced a developmental mechanism that enables substantial localized changes in morphology that remain well integrated into the structure and function of the organism.
The development and evolution of exaggerated morphologies in insects.
TLDR
It is argued that scaling relationships are best viewed as reaction norms, and that the evolution of exaggerated morphological traits results from genetic changes in the slope and/or shape of these scaling relationships.

Evolution of a Polyphenism by Genetic Accommodation
TLDR
It is shown that a mutation in the juvenile hormone-regulatory pathway in Manduca sexta enables heat stress to reveal a hidden reaction norm of larval coloration, facilitating the origin of novel adaptive phenotypes.
Competition among body parts in the development and evolution of insect morphology.

TLDR
In the case of beetle horns, the tradeoff in size is manifest as a significant negative genetic correlation among the involved body parts and constitutes a developmental source of genetic constraint on the evolution of body form.
Control of moulting and metamorphosis in the tobacco hornworm, Manduca sexta (L.): cessation of juvenile hormone secretion as a trigger for pupation.
TLDR
A functional failure of this normal mechanism is apparently responsible for the developmental standstill of Lepidoptera which diapause as mature larvae.
