(a) Reproductive development, composed of the variables C, SV & MG, was significantly correlated with body size, composed of the variables M, m, H, T & W (p < 0.0001). Though the coefficients for the principal components were generated from flight-aged drones (11 + d), this correlation holds over the entire lifespan of drones; (b) Both principal components vary significantly by age (p < 0.05). Body size (black circle) varied in a relatively linear fashion, with older drones being smaller than younger drones. Reproductive development (yellow diamond) varied along a quadratic function, with drones aged 16 days being the most reproductively developed.
