Migration is a complex behavior involving the synchronisation of many physiological and behavioral processes. Environmental cues must thus be interpreted to make decisions regarding resource allocation between, for example, migration or reproduction. In butterflies, lack host plants sustain new generation may indicate need migrate. Here, we used painted lady butterfly ( Vanessa cardui ) as model characterize gene expression variation in response plant availability. Assessment availability adult female butterflies revealed significant modifications expression, particularly within hormonal pathways (ecdysone oxidase juvenile hormone esterase). We therefore hypothesize that tuning ecdysone pathway play crucial role regulating timing reproduction butterflies. addition, our analysis enrichment genes associated with lipid, carbohydrate, vitamin biosynthesis, well immune response. As environmental acquisition occurs throughout life cycle, also tracked responses two other across major developmental stages. Differences both larval crowding during development resulted changes involved development, metabolism, at instar V stage. summary, results offer novel insights into how affect profiles migratory insects highlight candidate underpin syndrome butterfly.
