Yponomeuta sedella Treitschke, 1832
[Lepidoptera: Yponomeutidae]


Yponomeuta sedella Treitschke, 1832


Leaf-miner/Leaf-spinner: Numerous, short, narrow galleries, mainly in the basal half of the leaf. Frass in a central interrupted line. The older larvae live free under a communal web (Bladmineerders van Europa).

The larvae initially mine the leaves, making narrow galleries and then feed gregariously in a slight web (British leafminers).

Larva: The larva is illustrated in Bladmineerders van Europa and British leafminers.

Pupa: See Patočka (1997a), Patočka & Turčáni (2005a) (Bladmineerders van Europa).

Adult: The adult is illustrated in UKMoths. The male genitalia, but not the female genitalia (check for update), are illustrated by the Lepidoptera Dissection Group.

Hosts in Great Britain & Ireland:

Lamiaceae        
Sedum telephium Orpine British Wild Flowers by John Somerville et al. British leafminers

Hosts elsewhere:

Lamiaceae        
Rhodiola rosea     Bladmineerders van Europa
Sedum telephium Orpine British Wild Flowers by John Somerville et al. Bladmineerders van Europa

Time of year - larvae: June-July; September-October (British leafminers). Larvae in June-July and September - October (Agassiz, 1996a), but only the young larvae of the first generation do mine (Hering, 1957a) (Bladmineerders van Europa).

Time of year - adults:There are two generations, adult moths being on the wing in April and May, and again in August. The moth can be taken at light (UKMoths).

Distribution in Great Britain & Ireland: Widespread in England and Wales (NBN Atlas). It is fairly locally distributed in the southern half of Britain, north to the Midlands, although there are records from Northumberland too (UKMoths).

Distribution elsewhere: Widespread in continental Europe including Austria, Belgium, Bulgaria, Czech Republic, Estonia, Finland, French mainland, Germany, Hungary, Italian mainland, Latvia, Lithuania, Luxembourg, Macedonia, Norwegian mainland, Poland, Romania, Sicily, Slovakia, Spanish mainland, Sweden, Switzerland, The Netherlands, Ukraine and Yugoslavia(Karsholt and van Nieukerken in Fauna Europaea).
