The influence of three photoperiods, viz. short day [8 : 16 h; light : dark (L : D)], long day (16 : 8 h; L : D) and continuous light (24 : 0 h; L : D) and four wavelengths of light, viz. white (control), yellow, blue and red on pre‐imaginal development and reproductive performance of a ladybird, Coelophora (= Lemnia ) saucia (Mulsant) (Col., Coccinellidae) have been investigated under laboratory conditions. Long‐day photoperiod and white light resulted in low immature stage mortality. Total larval period was longest under short‐day and red‐light conditions. Females kept at long‐day photoperiod and under white light showed better reproductive performance than those placed under other photoperiods and wavelengths.
