02Description

Species Profile

Parornix torquillella is a moth of the family Gracillariidae found in Europe. The larvae mine the leaves of Prunus species, such as blackthorn. It was described by the German entomologist Philipp Christoph Zeller in 1850, from specimens found in Florence, Leghorn and Pisa.

Parornix torquillella faces significant decline primarily due to habitat loss and degradation of its specialized host plant environments. The species is particularly vulnerable because of its narrow ecological requirements and dependence on specific plant communities that are increasingly fragmented and destroyed.
