- Summary:
- This document describes how since the formation of the Hawaiian archipelago five million years ago, thirty-eight species of crickets from the genus Laupala Otte have derived from a single common ancestor. While this species have emerged as a model system in the study of several evolutionary processes, such as the differentiation of signaling phenotypes, the evolution of female preferences, and the phylogeographic patterns of speciation, very little is understood concerning the basic biology of species within this genus. As a result, the objective of this study was to examine the postembryonic development of two closely related species of these crickets -- the Laupala kohalensis Otte and the Laupala paranigra Otte because while these crickets are closely related, they exhibit widely divergent pulse rates of the male calling song that produced dramatically different calling songs, and are members of a rapid, recent, and extensive diversification of Hawaiian crickets. Here, morphometric image analysis of developing individuals is described from hatching through to adult maturation, to delineate instars in each species and a molecular mechanism linking the evolution of song pulse rate and developmental rate is discussed.
