Epermenia falciformis
Epermenia falciformis, also known as the large lance-wing, is a moth of the family Epermeniidae found in Europe. It was first described by Adrian Hardy Haworth in 1828. DescriptionThe wingspan is 9–11 mm. Forewings pale ochreous; costa fuscous on anterior half; an indistinct fuscous streak from base of dorsum to beneath 1/3 of costa; a rather dark ochreous-fuscous fascia from middle of costa obliquely inwards, dilated on costa, emitting from dilation a streak to tornus; an inwardly oblique dark ochreous-fuscous spot on costa before apex; second discal stigma dark fuscous; two black dorsal scale-teeth; dark line of cilia subfalcate at apex. Hindwings dark grey. Larva yellow-green; dorsal line darker head yellowish-brown. [2] Adults are on wing from June to July and again from August to September in two generations per year.[3] Ova are laid on angelica (Angelica sylvestris) and ground-elder (Aegopodium podagraria) in June and July, and in the Autumn.[4] Larvae of the first generation feed in May and June in spun leaflets of their host plant, while larvae of the second generation mine a stem immediately below an umbel, causing it to droop and wither. When full grown, larvae leave via a small hole just before the junction above the main stem.[4] Pupation takes place in an open network cocoon amongst detritus on the ground.[5] The threads spun by the larva are covered with minute drops of a sticky secretion. DistributionIt is found in Austria, Belgium, the Czech Republic, Denmark, France, Fennoscandia, Germany, Great Britain and Ireland, Latvia, the Netherlands and Slovakia. References
