Environmental drivers of phenotypic and behavioral changes are documented in model organisms but have been described in only a few butterfly and moth (Lepidoptera) species. Therefore, there exists an opportunity to develop Lepidoptera models of phenotypic plasticity. Plodia interpunctella Hübner (Pyralidae) is a globally widespread pest of stored food products. P. interpunctella larvae are primarily beige, but relatives in tribe Phycitini exhibit a variety of larval coloration and patterns. Other larval color morphs in P. interpunctella have been anecdotally linked to stress. In the current study, rearing trials were conducted on P. interpunctella under temperature stress to assess changes in larval color over the course of development. Larvae were photographed with a color card at final instar and larval color was quantified for statistical analysis. Additionally, user-uploaded images from BugGuide and iNaturalist were evaluated to compare color diversity in larvae across tribe Phycitini.
