ABSTRACT We tested how morphological traits and species diversity of Pyraloidea moth assemblages vary across an Andean rainforest elevational gradient in Ecuador, environmental conditions shape these patterns. analyzed 4161 individuals representing 212 from a larger dataset 10,337 749 morpho‐species, using the latter for cross‐validation, related our findings to ambient temperature vegetation cover. Our multivariate analysis at 22 sites 1020 2700 m above sea level identified five assemblage clusters, revealing near‐linear decrease with cooler temperatures. Community‐weighted means (CWMs) forewing length, indicating body size, increased nearly linearly dropping temperatures, contrasting results found Geometridae moths same sites. Forewing aspect ratio (AR) demonstrated U‐shaped relationship temperature, while wing loading (WL) followed hump‐shaped trajectory. Around 2000 m, exhibited lowest AR highest WL, adaptations dense forests, contrast both more open forests near treeline tall lower elevations. Subfamily‐level analyses revealed variable patterns: Acentropinae, strictly aquatic larvae, showed sizes elevations but less variation, likely reflecting limited forest dependence on maneuverability. Musotiminae, larval diet diverse ferns, morphologies canopy openness than navigating different fern habitats along gradient. observations reveal complex insect–environment interactions that challenge applicability just one common theoretical framework explaining temperature–size relationships among clades.

Abstract While variation in temperature appears to be the main environmental cue for plasticity adult traits many species of Mycalesina, relying on would result a mismatch between phenotype and environment some regions. We measured phenotypes six Bicyclus butterflies (Nymphalidae: Satyrinae: Mycalesina) humid tropical forest with two rainy seasons per year modest unimodal seasonal variation, such that does not predict rainfall can reproduce year‐round. The showed subtle temporal body size relative eyespot size, while androconia length was robust variation. After higher temperatures, tended smaller, larger species‐eyespot combinations. This indicates these follow “hotter is smaller” rule, show developmental typical this clade. Eyespot sizes correlated each other, except Cu1 B . auricruda eyespots always remained very small. Androconia related size. pattern correlations suggests conserved cue‐use shared mechanisms using both rainfall‐related cues, exceptions.

Insects often show adaptive phenotypic plasticity where environmental cues during early stages are used to produce a phenotype that matches the environment experienced by adults. Many tropical satyrine butterflies (Nymphalidae: Satyrinae) seasonally polyphenic and distinct wet- dry-season form adults, providing tight environment-phenotype matching in seasonal environments. In studied Mycalesina butterflies, forms can be induced laboratory growing larvae at low temperatures or on poor food quality. Since both these factors also tend reduce larval growth rate, rate may an internal cue translates into expression of phenotypes. If this is case, we predict slower-growing would more likely develop phenotype.
