Ectoedemia argyropeza (Zeller, 1839)
[Lepidoptera: Nepticulidae]

Virgin Pigmy


Lyonetia argyropeza Zeller, 1839. Isis: 215.
Ectoedemia argyropeza
(Zeller, 1839).


Galler and Leaf-miner: Gall in petiole, later mine in leaf-blade, in 'green island' (British leafminers). Check fallen leaves.

Oviposition on the petiole, c. 1 cm below the base of the leaf. The larva begins its life as a borer in the petiole, causing it to swell somewhat. When the leaf disc is reached the larva makes an elongate blotch between the midrib and the first lateral vein. Frass in two stripes parallel to the sides of the mine. Pupation external. The larvae are active mainly at night, retreating into the petiole during daytime (Johansson et al., 1990a) (Bladmineerders van Europa).

Larva: The larvae of moths have a head capsule and chewing mouthparts with opposable mandibles (see video of a gracillarid larva feeding), six thoracic legs and abdominal legs (see examples).

The larva is illustrated in Bladmineerders van Europa.

Pupa: The pupae of moths have visible head appendages, wings and legs which lie in sheaths (see examples).

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

Hosts in Great Britain & Ireland:

Time of year - larvae: July - November (British leafminers).

Time of year - adults: There is a single generation, and the adults are on the wing in May and June. It is believed to be parthenogenetic over most of its UK range (UKMoths).

Distribution in Great Britain & Ireland: Locally distributed throughout mainland Britain, though more plentiful in the south (UKMoths) including Banffshire (VC94), Bedfordshire (VC30), Breconshire (VC42), Caernarvonshire (VC49), Cambridgeshire (VC29), Cheshire (VC58), Denbighshire (VC50), East Kent (VC15), East Norfolk (VC27), East Suffolk (VC25), East Sutherland (VC107), Elgin, Herefordshire (VC36), Hertfordshire (VC20), Huntingdonshire (VC31), Middlesex (VC21), North Aberdeenshire (VC93), North Hampshire (VC12), Shropshire (VC40), South Aberdeenshire (VC92), South Wiltshire (VC8), South-west Yorkshire (VC63), Staffordshire (VC39), Surrey (VC17), West Gloucestershire (VC34), West Norfolk (VC28), West Suffolk (VC26) and Worcestershire (VC37) (NBN Gateway).
