Food Plant: Chenopodium urbicum (City Goosefoot), Chenopodium album (Fat Hen), Spinacia oleracea (Spinach), Hyoscyamus niger (Stinking Nightshade), Beta vulgaris (Beet), Silene vulgaris (Bladder campion)

Egg: underside of leaf

Mine: late Spring, late Summer

Notes: Makes a large upper surface whitish blotch, which can contain several larvae. The frass has a washed out appearance and is greenish. There may be several mines on a leaf and eventually the leaf will be mined and then shrivel up. To identify this miner adults must be reared. An adult fly is shown - they cannot be identified from photographs, but need microscopic examination. Michael Ackland identified the adults which were reared from these illustrated mines.
