CHAMAECYPARIS. [Cupressaceae]

Three species of Chamaecyparis are recorded in Britain.

Two British miners are recorded on Chamaecyparis.

A key to the European miners recorded on Chamaecyparis is provided in Bladmineerders van Europa.

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.

Argyresthia cupressella Walsingham, 1890 [Lepidoptera: Yponomeutidae]
