Pegomya hyoscyami (Panzer, 1809) [Diptera: Anthomyiidae] Anthomyia hyoscyami Panzer, 1809. Faunae insects germ. Fasc 108: 13. Chortophila chenopodii Rondani, 1866. Atti Soc. ital. Sci. nat., Milano 9: 162. Chortophila hyoscyami silenes Hering, 1924a. Z. wiss. InsektBiol. 19: 37.

Leaf-mine: Large blotch mine, often with several larvae, beginning with a short deeper corridor at a single egg shell on the surface of the leaf. The broad deep corridor later ends in a blotch but can be recognised (beneath the blotch) by its greater depth. Mine predominantly dorsal or ventral, greenish in transmitted light. Frass grains irregularly scattered except in the initial corridor. The mine is illustrated in Nederlandse bladmineerders. Mine of Pegomya hyoscyami on Atropa belladonna. Image: Willem Ellis (Source: Nederlandse bladmineerders) Larva: The eggs and larvae are described d'Aguilar & Missonier (1957 and 1962). The eggs are illustrated by Ellis (Nederlandse bladmineerders). Larva with bud-like posterior spiracles. Puparium: Details unknown. Comments: According to Michelsen (1980) hyoscyami is reliably recorded only from Beta and Chenopodium, Hyoscyamus and Silene.
