Common Oak Pigmy

<em>Stigmella roborella</em>, the common oak pigmy, is a minute leaf-mining moth in the family Nepticulidae, one of the smallest families of moths. The larvae of <em>Stigmella roborella</em> mine the leaves of oak trees (Quercus species), creating sinuous, narrow galleries within the leaf parenchyma that are characteristic of the genus. This species typically inhabits deciduous woodland, forest margins, parks, and hedgerows throughout temperate Europe wherever suitable oak host trees occur. Its geographic range includes Belgium, Denmark, Norway, and Sweden, reflecting a broad temperate European distribution. 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 on Quercus is well established in entomological literature. Adults are extremely small with narrow, metallic-patterned wings. <em>Stigmella roborella</em> contributes to the rich invertebrate biodiversity associated with European oak ecosystems and serves as an indicator of the ecological complexity supported by oak-dominated woodland habitats.
