CIRCAEA.
Enchanter's-nightshade. [Onagraceae]
|
Three
species of Circaea are recorded in Britain. These include
Enchanter's-nightshade (C. lutetiana).
Two British miners are recorded on Circaea.
A key to the European miners recorded on Circaea is provided in Bladmineerders van Europa. |

Circaea lutetiana |
Key for the identification of the known mines of British
insects (Diptera and non-Diptera) recorded on Circaea
|
1a > Leaf-miner: A
narrow contorted gallery leading to a whitish blotch with scattered
frass centrally. The early gallery can merge with the blotch and
there are often several to a leaf (British
leafminers).
The
larva begins by making a full depth corridor, erratic in width and
course; frass black, in an irregular central line. Later the larva
makes a blotch, with frass in irregular clouds. This blotch can
be a continuation of the corridor, but may just as well be on a
different leaf. Often several mines in a leaf; in such cases the
entire leaf me be mined out. Mines white at first, turning brown
later. The larva lies venter-upwards in the mine. Pupation external Bladmineerders van Europa). |

On Circaea and Epilobium in Britain and Chamerion,
Circaea and Epilobium elsewhere. Widespread in England
and continental Europe.

Mompha
langiella (Hübner, 1796) [Lepidoptera: Momphidae]. |
1b > Leaf-miner: Early mines are spiral galleries; later forms pale blotches, sometimes
having moved to a different leaf (British
leafminers). Egg at the upperside of the leaf, not near the
midrib. The larva starts by making a long, narrow, full depth corridor
that is strongly spiraled or even lies in intestine-like loops.
Frass as fine grains, distributed, later in a central line. After
a while a new mine is made, either a continuation of the corridor
or, more often, in a new leaf. This new mine begins as a narrow
corridor but soon widens into a large blotch; here the fass lies
in a broad band. The larva lies venter-upwards in the mine. Pupation
external (Bladmineerders van Europa). Pupation in a cocoon, on a leaf or in leaf-litter (British
leafminers). |

On Circaea and Epilobium in Britain and Circaea elsewhere. Widespread in Britain. Also recorded in
Northern Ireland and continental Europe.
