usually pupates in the mine some distance from the dead host. Pupal stage: The pupa lies between the upper and lower epidermis of the leaf which are held apart [...] Adult stage: The appearance of the adult is already clearly visible. Pupae are often visible through the leaf. The parasitic wasp escapes from the mine by making [...] particularly the serpentine leafminer ( Liriomyza trifolii ). The female wasp deposits her eggs inside the larvae of the leafminer, where the emerging larvae
