Phylloporia bistrigella

Distinguished from other small Incurvariidae by the straight (not curved) whitish fascia at one-third combined with a second fascia beyond the middle. The second fascia may be interrupted, and a whitish discal spot may be present beyond it. The ochreous-fuscous head coloration also aids identification.

Small moth with wingspan 7–9 mm. Head ochreous-fuscous. Forewings fuscous with a straight shining whitish fascia at one-third, and another sometimes interrupted fascia beyond the middle; sometimes with a whitish elongate discal spot beyond the second fascia. Hindwings grey.

Associated with birch woodlands and areas where Betula species occur.

Western, northern and central Europe; north-eastern North America. Recorded from Belgium (Flemish and Walloon regions, Antwerpen province).

Larvae feed on Betula species (birch).

• Betula - larval hostlarvae mine leaves

Larvae mine the leaves of their host plant.

Adults presumably active during day; larvae create leaf mines on birch.

Leaf miner on birch; contributes to nutrient cycling in birch-dominated ecosystems.

• Other IncurvariidaeSimilar size and general appearance, but P. bistrigella distinguished by straight (not curved) first fascia and presence of second fascia
• Phylloporia speciesCongeners may share host associations; specific wing pattern characters (straight fasciae, interrupted second fascia) separate bistrigella
