Spalgis epius (Lepidoptera: Lycaenidae) has been recorded as a potential predator of various species of mealybug crop pests worldwide. We describe the mass rearing of S. epius, as no information on this topic is available. Outdoor nylon tent cages of different dimensions were provided to achieve mating and oviposition as S. epius adults did not mate in the laboratory cages. Adults mated only in the tent cage (6 x 6 x 10 m) placed over a native tree (9 m height). The presence of a tree canopy inside the cage is essential to achieve courtship and mating. Gravid females of S. epius deposited eggs on the mealybug-infested pumpkins inside the different sized nylon cages with or without a bush/tree. Spalgis epius eggs were maintained on mealybug-infested pumpkins in the laboratory and developmental stages of the predator were reared. Adults fed on various diets laid significantly higher number of eggs than those of starved individuals. Spalgis epius with a life cycle completed in 21.2 days and 55.7 larvae, could be reared on a single mealybug-infested pumpkin.
