Coleophora argentula
Wingspan 9.5 to 13 mm. This moth is similar to some other Coleophora species and gen det is necessary for identification.
The females lay their eggs on the flowers of Yarrow or Sneezewort and favour areas where either of these plants is present.
This moth emerges in a single generation, flying in July and August, sometimes coming to light.
Early instars of the larvae are spent within the seedhead. Each forms a silken case, initially white, but brown when fully formed and about 5 or 6mm long. Pupation takes place within the case.
The moth is widespread in Southern England and Wales, and is also found in Central Scotland. 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).
