The larvae of the Agromyzid fly Liriomyza pusilla create irregular but linear mines on the upper surface leaves of Daisy (Bellis perennis). The mine winds across the leaf, often crossing over itself. Small leaves may have a secondary blotch at the end of the mine. Frass, when visible, is in short pearl-like strings. Pupation takes place outside the mine.

See the National Agromyzidae Recording Scheme webpage for this species for further details of puparium and adult insect.

Leafmines are mostly recorded between June and November, but may be visible in Daisy leaves for much of the year.

In Britain this species is classed as Nationally Scarce B.
