Phyllocnistis citrella Stainton, 1856
[Lepidoptera: Gracillariidae]

NOT BRITISH


Phyllocnistis citrella Stainton, 1856. Trans. ent. Soc. Lond. (n.s.) 3: 302.


Leaf-miner: Long epidermal corridor with a well-marked central frass line. Mine mostly lower-surface, less often upper-surface, and rarely on the rind of the developing fruit. Pupation, as in all Phyllocnistis species, in a chamber at the end of the corridor, under an overturned part of the leaf margin (Bladmineerders van Europa).

The mines on leaves and a fruit are also illustrated in and 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).

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

Hosts in Great Britain & Ireland:

Rutaceae        
Citrus       British leafminers
Citrus       Pitkin & Plant

Hosts elsewhere:

Rutaceae        
Citrus       Bladmineerders van Europa

Comments: Mainly on Citrus species, but also on other genera of the same family (Rutaceae). The species seems to be native to Asia, but is found now in all regions where Citrus species are cultivated, and is a very serious pest there Bladmineerders van Europa. A tropical species which is not yet a British species. Most specimens are intercepted at points of entry. It is a pest of commercial citrus orchards (British leafminers).

Time of year - larvae: Throughout the year (British leafminers).

Time of year - adults: Currently unknown.

Distribution in Great Britain & Ireland: Found and reared from Citrus from a garden centre in Burford, Oxfordshire by Robert Homan (British leafminers - Newsletter 26) and Entomologist's Rec. J. Var
(124) 2012 :279-281.

Distribution elsewhere: Widespread in continental Europe including the Azores, Balearic Is., Canary Is., Greek mainland, Italian mainland, Madeira, Malta, Portuguese mainland, Sardinia, Spanish mainland. Also recorded in Afro-tropical region and Nearctic region (Karsholt and van Nieukerken in Fauna Europaea).
