Common thorn midget

<em>Phyllonorycter oxyacanthae</em>, the common thorn midget, is a small moth in the family Gracillariidae whose larvae mine the leaves of hawthorn (<em>Crataegus</em>) and related rosaceous plants. It is recorded from seven European countries and is classified as Endangered on the IUCN Red List, reflecting population declines attributed to habitat loss, changes in hedgerow management, and the decline of hawthorn-dominated habitats across its European range. Adults are small, with golden-orange forewings marked with white strigulae typical of the genus. Larvae create distinctive blotch mines on host leaves, feeding on the lower epidermis and mesophyll. The species undergoes multiple generations per year in favorable conditions, with adult flight periods typically in spring and late summer. As an Endangered species, targeted conservation of hawthorn-rich hedgerows, scrub, and woodland edges is essential for its persistence. Biological traits such as precise wing dimensions, adult lifespan, and larval development duration remain poorly documented in standardized assessments.
