Gypsonoma oppressana
This record describes Gypsonoma oppressana (species). Recorded family: Tortricidae. Recorded order: Lepidoptera.
Identification and Appearance
Wingspan about 14 mm. The larva mines the leaves of Poplar species, making a short corridor along midrib and often into the side vein; they then feed on the leaf under-surface inside a silken tube covered in frass. The larva is red-brown, which helps to distinguish from Gypsonoma dealbana . Gypsonoma dealbana makes similar feeding signs on poplars Only tenanted mines can be recorded. Photograph the mines on leaf under-surface, and the larva. Flies during June and July in a single generation. The larva feeds on Poplar (Populus), initially grazing the underside of a leaf, from within a silken tube which becomes covered with frass. A relatively local species, occurring sporadically throughout England. In the Butterfly Conservation's Microlepidoptera Report 2011 this species was classified as Nationally Scarce B. http://www.leafmines.co.uk/html/Lepidoptera/G.oppresana.htm https://bladmineerders.nl/parasites/animalia/arthropoda/insecta/lepidoptera/ditrysia/apoditrysia/tortricoidea/tortricidae/olethreutinae/eucosmini/gypsonoma/gypsonoma-oppressana/#:~:text=The%20young%20larva%20makes%20a,causes%20under%2Dsurface%20window%20feeding.

About Butterflies and Moths: the wider group
Order-level background for Lepidoptera, the group containing Gypsonoma oppressana. Species-specific details appear above.
Group overview
Lepidoptera includes approximately 180,000 described species of butterflies and moths. Moths outnumber butterflies roughly 10:1. The monarch butterfly's eastern population has declined by more than 80% since the mid-1990s, and the western population by over 95% since the 1980s. The IUCN lists the migratory monarch as Vulnerable.
Ecological role of the group
Butterflies and moths are essential indicators of ecosystem health. As caterpillars, they are a primary food source for birds - a single nest of blue tit chicks requires ~10,000 caterpillars. Adult moths pollinate many night-blooming plants.
Economic and practical significance of the group
Lepidoptera are critical pollinators. In Europe, grassland butterfly species have declined by almost 50% since the early 1990s. In the UK, three-quarters of butterflies are in decline. In the U.S., five butterfly species have gone extinct since 1950, with 29 listed as endangered.
