Pale shoulder

Description

Acontia lucida, the pale shoulder, is a moth of the family Noctuidae. The species was first described by Johann Siegfried Hufnagel in 1766. This species can be found in most of Europe, east to Turkey, Iran and India. It has also been recorded from Algeria. It is a rare migrant to the south coast of Great Britain. The pale shoulder can be found in grasslands, dry meadows, steppes, dunes and roadsides, where the host plants are present. The wingspan of Acontia lucida can reach 26–30 mm. Head, thorax and abdomen are white. The forewings show a greyish-white front part and a wide dark brown median band, dark mottled and marbled, larger in the centre. A white mark is present on the outer edge of the forewings, while a brown mark is close to the apex. Hindwings are whitish fuscous, with a brown band near the apex. Larvae are green or brown, with transversal whitish bands. The larvae are polyphagous, feeding on various herbaceous plants, mainly on mallow (Malva species), common marshmallow (Althaea officinalis), field bindweed (Convolvulus arvensis), goosefoots (Chenopodium) and dandelion (Taraxacum). Adults are on the wing on sunny days in May and August in two generations. They are attracted to light. This species overwinters as pupa below ground. Rarely it is a migrant species. Acontia is a genus of moths of the family Noctuidae. The genus was named by Ferdinand Ochsenheimer in 1816. Eusceptis, Pseudalypia and Spragueia are sometimes included in the present genus, but here they are tentatively treated as different pending further research. Many species of Tarache were also once placed here. Palpi long, porrect (extending forward) and met by a short sharp frontal tuft. Third joint prominent. Antennae simple. Thorax and abdomen smoothly scaled and tuftless. Forewings with non-creulate cilia. Veins 7, 8 and 9, 10 stalked. Larva possess four abdominal prolegs.
