Common sawfly

<em>Fenusella hortulana</em> is a small sawfly belonging to the order Hymenoptera and the family Tenthredinidae, a diverse group of plant-feeding insects commonly known as leaf-mining sawflies. This species is distributed across parts of Europe and North America, where it is typically associated with deciduous woodland edges, hedgerows, and gardens that support its host plants. Like other members of its genus, <em>Fenusella hortulana</em> typically undergoes complete metamorphosis, with larvae mining the leaves of woody plants, creating distinctive blotch or linear mines visible to observers. Adults are generally small and inconspicuous, resembling miniature wasps. The species has not been formally evaluated by the IUCN, and its global population status remains unknown. Biological traits for this species remain poorly documented in the scientific literature, including specific data on lifespan, body dimensions, weight, and detailed dietary preferences beyond general leaf-mining behavior. Conservation concern is currently low given its apparently stable presence across its range, though habitat degradation may affect local populations.
