The Robber Fly in the above pictures seems laying eggs on loose bark. In general, female robber flies deposit creamy colour eggs on plants or in gaps within soil, bark, or wood. Egg-laying habits are different depend on species and habitat. Most species lay eggs in masses and are covered with protective coating. Robber fly larvae live in the soil or in rotting wood. Larvae are either predatory or parasitic, they feed on eggs, larvae and other soft-bodied insects.
