1 > Leaf-miner and case-bearer: The larvae feed on the needles. When occurring in large numbers, entire trees can be damaged, the needles turning pale as the larvae eat them from within. A number of cases are built as the larvae grow, often in the centre of a floret of needles.

On Larix, but not yet on Pseudotsuga, in Britain. On Larix and Pseudotsuga elsewhere. Widespread in Britain, Ireland and continental Europe.
