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. |

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.
Larvae light yellow, with darker thoracic legs (British
leafminers). The larva is also illustrated
in Bladmineerders van Europa.

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

1b > Leaf-miner: Early mines are spiral galleries; later forms pale blotches, sometimes
having moved to a different leaf. 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 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).
Larvae hitish; head light brown; prothoracic and anal shield yellowish brown (Koster, 2002b; Koster and Sinev, 2003a) (Bladmineerders van Europa).
Pupation in a cocoon, on a leaf or in leaf-litter (British leafminers). See also See Patočka and Turčáni (2005a) (Bladmineerders van Europa). |

Northern Ireland and continental Europe.
