Confusion Species: Coleophora coracipennella
Blackthorn Case-bearer; Coleophora prunifoliae
Sloe Case-bearer

Distribution: Old records from 1917-1926 Repton appear to be dubious and would have required Gen Det due to incorrect food plants recorded. Species feeds principally on Malus & Prunus not on Elm or Osier as per detail in Harrison & Sterling 1986.

Flight Period: June / July / - single generation

Mine Period: January / February / March / April / May / September / October / November / December / - A blotch mine is made by the larvae in the leaf, which it then cuts out to form its case. The larva overwinters in its case before resuming feeding in spring. A new case, 6-7mm long, is then constructed from a further blotch mine.

Moth Activity: Cathemeral - occasionally attracted to light
