Data: Independent major-effect loci and limited trait associations characterise warning colour variation across sexes and life stages in the wood tiger moth (Arctia plantaginis)

Several traits were measured in a laboratory reared population of the wood tiger moth Arctia plantaginis. The ancestors were of Finnish origin and the population was maintained over more than 20 generatios. Traits measured included hindwing colour and size, activitity behaviour, pheromone and defence fluid composition. The columns in the data refer to: ID: Individual ID; family: full-sib family of respective individual; male_colour: hindwing colour of adult males. It is a dimorphic trait, yellow or white; male_melanin: presence or absence of a dark patch on male hindwings; rg_wing: 'redness' of hindwings of adult females quantified from images; rg_body: 'redness' of bodies of adult females quantified from images; female_colour: female hindwing colour quantified by visual matching against a colour scale ranging from 1-6, where 1=yellow and 6= drak red; signal_size_final: signal size of larvae (orange patch on their black back) quantified as number of body segments with orange hair; prop_larvae_colour: signal size of larvae quantified from images; rg_larva_fullpatch: 'redness' of orange patch in larave quantified from images; larval_weight_mg: weight of larvae; pupa_weight_mg: weight of pupae; Tot_phero_amount.log: amount (log-transformed) of the two main compounds P3 and P6 in the female sex pheromone. Absolute amounts (in ng) of each compound were calculated relative to the 200 ng of internal standard; Ratio_P6.P3.log: ratio of the second major compound (P6) was calculated over the amount of the major compound (P3) and log-transfomed; sig larva.time: time in the laval stage (from hatching to pupation) in days; Sex, FW_size: fore wing size quatified from images; HW_size: hindwing size quantified from images; propMelanin_FW: melanised proportion of the forewings quantified from images; propMelanin_HW: melanised proportion of the hindwing quantified from images; UV_l and UV_r: Uv brightness; IBMP.log : IBMP (2-isobutyl-3-methoxypyrazine) concentration (log-transformed), the main defence compounds in the defensive neck fluids of adults. SBMP.log: 2-sec-butyl-3-methoxypyrazine concentration (log-transfomed) in the neck fluids of adults; IBMP.SBMP.ratio.log: ratio of neck fluid compounds; res.time_flipped, res.amount_A , res.amount_K, res.amount_L, res.amount_R, res.amount_M, res.n_active_mins, res.sum_activities: Activity behaviours in minutes during a 45-minute trials. Time until the moth flipped from its back to its front ('flipped'), number of minutes during which there was any antenna movement (amount A), walking (amount K), fluttering of the wings (amount R) or flying (amount L), other movement (amount M), sum (in minutes) of all activities observed, and the number of minutes when any forms of activity was observed. Measurements were corrected for weather (factor: cloudy, half cloudy, sunny/half cloudy, sunny), and temperature using the residuals of linear models that included these confounding factors. To ensure normality, residuals were square-root transformed after adding the minimum residual value to obtain onlypositive values.
