Delia antiqua, commonly known as the onion fly, is a cosmopolitan pest of crops. The larvae or maggots feed on onions, garlic, and other bulbous plants. The onion fly has an ash-grey body and resembles a housefly.

Understanding the Context

The male has a longitudinal stripe on the abdomen which is lacking in the female. The adult onion fly resembles a greyish housefly, with a narrower abdomen, longer legs, and overlapping wings when at rest. Keep an eye out for these flies in your garden, as they lay their eggs near the base of onion plants. Protect onions and related crops from onion fly damage with practical prevention tips.
