Abstract
Terpenes are a major class of secondary metabolites present in all plants, and long hypothesized to have diversified in response to specific plant-herbivore interactions. Herbivory is a major biotic interaction that plays out across broad temporal and spatial scales that vary dramatically in temperature regimes, both due to climatic variation across geographic locations as well as the effect of seasonality. In addition, there is an emerging understanding that global climate change will continue to alter the temperature regimes of nearly every habitat on Earth over the coming centuries. Regardless of source, variation in temperature may influence herbivory, in particular via changes in the efficacy and impacts of plant defensive chemistry. This study aims to characterize temperature-driven variation in toxicological effects across several structural classes of terpenes in the model herbivore Vanessa cardui, the painted lady butterfly. We observed a general increase in monoterpene toxicity to larvae, pupa, and adults at higher temperatures, as well as an increase in development time as terpene concentration increased. Results obtained from this study yield insights into possible drivers of seasonal variation in plant terpene production as well as inform effects of rising global temperatures on plant-insect interactions. In the context of other known effects of climate change on plant-herbivore interactions like carbon fertilization and compensatory feeding, temperature-driven changes in plant chemical defense efficacy may further complicate the prediction of climate change impacts on the fundamental ecological process of herbivory.

The dataset contains three CSV files containing hatching, development, and adult mass data for a toxicological study assessing the effect of temperature on the efficacy of plant terpenoids against the thistle caterpillar, the larval form of the painted lady butterfly (Vanessa cardui). Full methods can be found in the publication of record, which is open access.
Description of the data and file structure
Dataset S1. Full data on Vanessa cardui hatching failure and larval, pupa, and adult mortality presented as counts and proportions. Run represents individual trial runs, and temperature is presented in Celsius. Concentration of each terpene is presented in w/w percentage as prepared at the start of each trial.
Dataset S2. Full data on Vanessa cardui development time from hatching to pupation, and from hatching to eclosure (emergence from pupa). Run represents individual trial runs, and temperature is presented in Celsius. Concentration of each terpene is presented in w/w percentage as prepared at the start of each trial. NA=not applicable, indicating missing data as the insect did not reach the relevant developmental stage.
Dataset S3. Full data on Vanessa cardui post-eclosure dry mass (in grams) for fully-formed adults. Run represents individual trial runs, and temperature is presented in Celsius. Concentration of each terpene is presented in w/w percentage as prepared at the start of each trial.
Supplemental Figures S1-S5 are also included.
