Life Cycle of Oak leaf gall midge
Egg The egg of oak leaf gall midge is usually oval and diminutive, placed carefully on a substrate related to its future larval food. At this stage, the insect is a dormant embryo undergoing cell differentiation.
Larva Larvae of oak leaf gall midge emerge as legless grubs, primarily focused on feeding and growth. They lack distinctive features of adult insects and undergo a series of molts, increasing drastically in size.
Pupal The pupa of oak leaf gall midge is a non-feeding, immobile stage encased in a protective cocoon. Transformation inside includes developing wings, compound eyes, and adult body segmentation.
Adult Emerging from the pupa, the adult oak leaf gall midge's development is marked by the presence of wings and functional reproductive organs. Distinct adult coloration and hardened exoskeleton differentiate it from earlier stages.
