Cauchas fibulella - Cauchas fibulella
Wingspan 8 to 11 mm. The smallest of the British Adelinae, with a distinctive pale mark on the centre of the forewing, and often a second, smaller pale blotch nearer the base. Unlike some of its relatives, the antennae of the male are only slightly longer than those of the female.
Where the larval foodplant, Germander Speedwell (Veronica chamaedrys) is present.
The moths are on the wing in June and fly in sunshine, often visiting the flowers of the foodplant.
The foodplant is Germander Speedwell (Veronica chamaedrys), the larvae feeding initially on the seeds, later building a portable case from fragments of plant, and feeding on the leaves close to the ground.
In the Butterfly Conservation's Microlepidoptera Report 2011 this species was classified as common.
It appears to be uncommon in Leicestershire and Rutland, where there are few records. L&R Moth Group status = D (rare or rarely recorded).
