Phyllonorycter insignitella (Zeller, 1846)
[Lepidoptera: Gracillariidae]

Clover Midget


Lithocolletis insignitella Zeller, 1846. Linn. Ent. 1: 193, t. 1 fig. 13
Phyllonorycter insignitella
(Zeller, 1846).


Leaf-miner: Lower surface tentiform mine that occupies only part of a leaflet. In full grown leaves the mine is strongly inflated and is largely hidden by the leaf. Unlike other species the entire leaflet is not mined out (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).

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

Described by Gregor and Patocka (2001a) and Patcoka and Turcáni (2005); see also King and Murria (2002a). The pupa strongly resembles the one of Ph. medicaginella, but the 10th abdomen segment is clearly wider than long (as wide as long in medicaginella) and the cremaster spines are not notched just before the hooks. The constancy of these differences remains to be established (Bladmineerders van Europa).

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