AbstractArthropods are the most diverse phylum on earth, accounting for up to 90% of animal species. The cuticular exoskeleton has played a vital role in their evolutionary success, but we know surprisingly little about the factors influencing its development, structure, and biomechanical properties. In this study, we examined whether and how nutrition affects the cuticle after an insect has completed its final molt into the adult stage.

1 INTRODUCTION Many phytophagous insects are host–plant specialists (Bernays & Chapman, 1994). If insects are to expand or shift their host plant diet, they must be able to recognize a new host plant as food, survive, and reproduce when feeding on it (Rausher, 1983). Host range expansions can occur through bottom-up forces due to host plant availability, detectability, and suitability for the insect species (Miller, 2008; Vidal & Murphy, 2018).

Statistical analyses To test the hypotheses that wind speed and temperature influence the evolution of flight in stick insects, I conducted multiple phylogenetic logistic regressions (Ives & Garland, 2010) using phylolm (version 2.6.2; Ho & Ané, 2014) in R (version 4.2.1; R Core Team, 2022). Phylogenetic logistic regressions test whether the transitions to a given state (in this case, flying ability) is dependent upon another factor (in this case, temperature or wind speed).
