Celypha lacunana

([Denis & Schiffermüller], 1775)

Wingspan 16-18 mm.

A very common species throughout Britain, it can often be disturbed during the day from vegetation along woodland fringes, verges, grassy fields and hedges.

Later in the evening is the moth's normal flying time, when it can be attracted to light.

It has quite a long flight period, from May to August.

The larvae feed on a wide variety of herbaceous plants.

A species with many more larval varieties than illustrated. Please refer to more details below.

     Foodplants: August to June, overwinters off plant, in spun leaves, shoots and flowers of a wide range of herbaceous plants, ferns, shrubs and trees; Daucus, Succisa, Ononis, Mentha, Caltha, Ranunculus, Inula, Cirsium, Chrysanthemum, Lysimachia, Chenopodium, Urtica, Artemisia, Filipendula, Fragaria, Sanguisorba, Epilobium, Rubus, Salix, Betula, Ligustrum, Larix, Picea, Pteridium etc. 
    Length: 15 mm April described. 11mm specimen found 14thAug., pupated 25th Aug., emerged 30th Aug.1999; either delayed developer, or a second generation. 
    Head: Shiny black (various shades of brown marked black laterally) with yellowish white clypeus and brown labrum. 
    Prothorax (T1): Prothoracic shield black (various shades of brown) divided by a very fine medial line coloured as integument, anterior border as integument or a light greyish brown. Blackish prespiracular and subventral pinacula. 
    Mesothorax (T2): One pair widely spaced bisetose dorsal pinacula; one unisetose lateral pinaculum; two pinacula level with spiracles, the anterior bisetose; one subventral pinaculum. 
    Metathorax (T3): As T2 
    Thoracic legs: Black or pitchy brown. (yellowish, cream, brown).
