Leaf-miner
and case-bearer: The larva builds a distinctive 'pistol-case' with a 'handle' of
pale greyish silk (UKMoths).
The
full grown larva in a black pistol case of 7 mm long. The mouth
angle is c. 80°. From the rear end a grey silken cloak (pallium)
hangs down to almost halfway the mouth (Bladmineerders van Europa).
The
case is also illustrated in the Encyclopedia of Life.

elsewhere:
Time
of year - larvae: September to October, feeding again from April
to May or mid-June (British leafminers).
Time
of year - adults: July and August (UKMoths).
Distribution
in Great Britain and Ireland: Widespread in England, including
Bedfordshire, Cambridgeshire, East Kent, East Suffolk, Herefordshire,
Hertfordshire, Middlesex, North Essex, North Hampshire, North Somerset,
Northamptonshire, South Essex, South Wiltshire, Surrey, West Gloucestershire,
West Kent, West Norfolk, West Suffolk and Worcestershire (NBN
Gateway - N.B. includes Watsonian Vice Counties having publicly available records
that fall within or overlap the vice county border at 10km resolution or better i.e. a
record for a vice county may relate to an adjacent vice county - for included datasets see NBN Grid map below).
Confusion
over its distribution is compounded by the fact that this species
was formerly known as Coleophora ardeaepennella and the fact
that Coleophora betullela
on Betula has been misidentified as Coleophora
ibipennella (UKMoths).
