title: Data from: Predicting life history responses to global warming in insects: Which temperature and photoperiod should be used?

description: This dataset contains experimental data used to evaluate how different
 combinations of temperature and photoperiod influence developmental
 timing, growth rate, mass, and synchrony in the damselfly Lestes sponsa.
 The data were generated from six experimental treatments representing
 constant and seasonally varying thermal and photoperiodic regimes under
 ambient and warming scenarios. Each file includes individual-level
 measures of developmental time, growth rate, larval mass, and survival,
 along with treatment identifiers and metadata describing experimental
 conditions. These data can be reused for meta-analyses on insect thermal
 responses, photoperiodism, or life-history plasticity, and for modelling
 temperature–photoperiod interactions under climate change. All individuals
 were laboratory-reared under controlled conditions, and no ethical or
 legal restrictions apply to the use of these data.
description: Dataset for “Predicting life history responses to global warming in
 insects: which temperature and photoperiod should be used?” 1. Dataset
 description This dataset contains experimental data used to investigate
 how combinations of temperature and photoperiod affect development,
 growth, and survival in the damselfly *Lestes sponsa*. The experiment
 included six thermal–photoperiodic treatments representing constant and
 seasonally varying regimes under ambient and warming conditions. All data
 are provided in a single Excel file "lestes24_data.xlsx" with
 two sheets: Life_history_until_F0 – individual-level life-history data
 (hatching to F-0 instar). Survival_to_F0 – group-level survival data to
 the F-0 instar. 1. Sheet descriptions Sheet 1: Life_history_until_F0 * id
 - Unique identifier for each individual. * group - Experimental treatment
 group (see treatment codes below). * data.hatch - Date of hatching
 (DD-MM-YYYY). * date.F0 - Date when the individual reached the final
 instar (F-0). * dev.time - Total development time (days from hatching to
 F-0). * week - Week number in which the individual reached the F-0 instar.
 * sex - Biological sex of the individual (M = male, F = female). * mass -
 Larval wet mass (mg) measured at the F-0 instar. * growth - Growth rate
 (mg/day), calculated as mass divided by development time. Sheet 2:
 Survival_to_F0 * group - Experimental treatment group (see codes below). *
 survival - Number of individuals surviving to the F-0 instar in each
 treatment group. 1. Experimental design overview * Species: *Lestes

 * File format: Microsoft Excel (.xlsx) * Sheets: “Life_history_until_F0”
 and “Survival_to_F0” * Compatible software: Microsoft Excel, LibreOffice
 Calc, R, or Python (e.g., with readxl or openpyxl libraries). * No
 specialized software is required. 4. Ethical and legal considerations *
 All individuals were laboratory-reared from field-collected *Lestes
 sponsa* adults. No ethical or legal restrictions apply to the use of these
 data. 5. R code availability * The R scripts
 "lestes24_R_script.R" used for statistical analyses and figure
 generation are included as supplementary files in this Dryad repository.
 Each script is annotated and corresponds to analyses described in the
 manuscript sections “2.5 Statistical analyses” and “3 Results.”
