Phytomyza ranunculi
Ranunculus leaf-mining fly
Phytomyza ranunculi is a leaf-mining fly in the family Agromyzidae that develops within leaves of Ranunculus plants (buttercups). Adults are approximately 2 mm long and highly variable in coloration, with several named color variants. The larvae are primarily leaf-miners, forming long, conspicuous white mines with frass arranged in close strings. The species is widespread in Europe and occurs in the Palearctic region. Pupae are heavily parasitized, with up to 75% of puparia attacked by parasitoid wasps.
