Key for the identification of the known mines of British
insects (Diptera and non-Diptera) recorded on Chamaecyparis
|
1# > Leaf-miner: Details unknown. |
On Chamaecyparis, Cupressus and Juniperus in Britain.
Most records are from the south-east of England. Widespread in
continental Europe.

Gelechia
senticetella (Hübner, 1817) [Lepidoptera: Gelechiidae]. |
1a > Leaf-miner: Oviposition on a young shoot. The larva penetrates a leaf, empties
it, leaves it, often by making another hole in the epidermis, and
starts a new mine. Older larvae bore in a twig. Pupation external.
Mined twigs turn brown and are dropped. |

On Chamaecyparis, Cupressocyparis, Juniperus and Thuja in Britain and elsewhere. Widespread in Britain
and continental Europe.

Argyresthia
trifasciata Staudinger, 1871 [Lepidoptera: Yponomeutidae]. |
1b > Leaf-miner: During autumn the larva mines a mere 9-12 leaves - the damage is quite inconspicuous. Hibernation occurs within the mine, and during mild days feeding may continue. After hibernation the larva lives as a borer, and empties 4-6 shoots, over a length of 0.5 - 2.5 mm, just below the tip of the shoot. The damaged shoots wilt and die off. |
On Cupressaceae, but not yet on Chamaecyparis, in Britain and Chamaecyparis, Cupressocyparis, Juniperus and Thuja elsewhere.
