Researchers reviewed more than 50 scientific papers to learn about adaptations in laboratory-reared insects. Most of the papers dealt with flies (Diptera) or with butterflies and moths (Lepidoptera). In comparing the two orders, flies showed increased adaptations overall, with most being positive. Butterflies and moths showed fewer adaptations overall with a comparatively greater percentage of them being negative.
