Food Plant: Umbellifers such as Heracleum sphondylium (Hogweed), Angelica sylvestris (Wild angelica), Anthriscus sylvestris (Cow parsley), Daucus carota (Wild carrot), Pastinacea sativa (Wild parsnip)

Egg: Underside of leaf, usually near to the edge

Mine: May-June; August-September

Notes: Mine illustrated is on Hogweed. Moths bred through - emerged 04.vii.2005. The larva are often gregariuos and feed on the underside of the leaf causing a 'windowing' effect as they eat the mesophyll and lower epidermis. This effect can be seen from the top of the leaf as it discolours. Close up of a larva feeding on Daucus carota. Adult reared to confirm the ID.
