Wasp laying egg. Macrophotograph of a female parasitic wasp (Muscidifurax zoraptor) laying an egg in a housefly pupa with its ovipositor. Once the wasp larva hatches, it will feed on the housefly larva. As it kills disease-causing and crop-damaging species, this wasp is regarded as a beneficial insect. Magnification: x5 at 35mm size.
