The larvae or maggots feed on onions, garlic and other bulbous plants. ==Morphology and biology== The onion fly has an ash-grey body and resembles a housefly. The male has a longitudinal stripe on the abdomen which is lacking in the female. The legs are black, the wings transparent, and the compound eyes brown. The eggs are white and elongated and are laid in groups on the shoots, leaves and bulbs of host plants and on the ground nearby. The larvae are white and cylindrical and hatch in three to eight days. Each batch of larvae tends to keep together and collectively create large cavities in bulbs. More than fifty maggots may feed on one bulb, sometimes originating from eggs laid by several females. The larvae moult three times, feed for about twenty days, and grow to about one centimetre long. The pupa is brown, ringed and ovoid and measures long. Pupation occurs in the ground with the pupal phase from the spring generation lasting two or three weeks. Late generation pupae overwinter in the soil.〔(【引用サイトリンク】title=''Delia antiqua'' (Meigen) - Onion Fly )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Delia antiqua」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
