Common oak midget

<em>Phyllonorycter quercifoliella</em>, the common oak midget, is a very small moth in the family Gracillariidae. This leaf-mining species lays its eggs on oak leaves, and the larvae feed by mining within the leaf tissue, creating characteristic blotch or tentiform mines visible on the upper or lower surfaces of leaves. <em>Phyllonorycter quercifoliella</em> typically inhabits deciduous woodland, forest margins, parks, and hedgerows where oak trees (Quercus species) are present. Its geographic range spans temperate Europe, with documented occurrences in multiple countries including Belgium, Denmark, Norway, and Sweden, among others. The species is currently assessed as Least Concern by the IUCN. Biological traits such as lifespan, body size, and diet remain poorly documented at a formal population level for this species, though larval leaf-mining behavior on oak is well documented. Adults are tiny with narrow, patterned wings typical of the Gracillariidae family. <em>Phyllonorycter quercifoliella</em> is one of several oak-associated Gracillariid moths in Europe and forms part of the complex invertebrate community inhabiting European oak woodland ecosystems.
