Tachinid Fly - Peleteria Species

Family Tachinidae, commonly known as tachinid flies, are parasitoids, meaning that their larvae are parasitic on other arthropods.

Tachinid Fly - Peleteria Species

Tachinidae belongs to the superfamily Oestroidea. It is one of the largest families of Diptera, with over 10,000 known species worldwide. Most species measuring between 5 to 15 millimeters in length.

Life Cycle:

  • Egg: Tachinid flies lay their eggs on the bodies of host insects, typically near or on the host’s soft tissues.
  • Larva: The tachinid fly larva hatches from the egg and enters the host insect, where it feeds internally. The larva eventually kills the host.
  • Pupa: After consuming the host, the tachinid larva leaves the host and pupates in the soil or leaf litter.
  • Adult: The adult fly emerges from the pupa and is free-living. They feed on nectar and pollen, contributing to pollination.
