Stigmella microtheriella
Hazel leaf miner moth, Hazel Leafminer Moth
Stigmella microtheriella is a minute leaf-mining moth in the family Nepticulidae, with a wingspan of only 3–4 mm. The species is native to Europe and Asia, and was introduced to New Zealand from Britain between 1850 and 1860, likely via imported hazel trees. Its larvae create distinctive narrow, angular mines in the leaves of hazel (Corylus species) and hornbeams (Carpinus species). Adults are parthenogenetic and fly in May and August.
