< back
the cocoon is formed amongst the detritus on te ground usually - but may be on the leaf

 

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. The cocoon (as shown) is formed amongst detritus on the ground usually, but may be on the leaf.

Data: 19.vi.2005, Fleet, Hants, VC12
