Phyllocnistis ramulicola Langmaid & Corley, 2007
[Lepidoptera: Gracillariidae]


Phyllocnistis ramulicola Langmaid & Corley, 2007. Ent. Gazette 58 (4): 227-237.


Stem-miner: The eggs are laid in the stem in the current year's growth and the whitish mine progresses up the stem terminating at the base of the leaf. The larva curls over the leaf edge to pupate (Langmaid & Corley, 2007).

Oviposition on a young twig. From there a long corridor is made in the bark, up to 30 cm in length, running up or down, hardly widening. Finally the corridor enters a petiole and a leaf where, close to the base, at the upperside, a white cocoon is spun in which pupation takes place (Bladmineerders van Europa).

The mine is also illustrated in British leafminers.

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).

Black (Bladmineerders van Europa).

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