Bryotropha terrella is a moth of the family Gelechiidae. It is the type species of the genus Bryotropha. It is found in Europe. The wingspan is 14–16 mm. Forewings very variable in ground colour - dark fuscous, shades of brown and grey to cream (coastal form), dark shining bronzy base of costa purplish-tinged. Variously showing the ‘bryotropha’ spots, a sub-terminal fascia and spots around the wing tip or unicolorous. Hindwings grey. Certain identification is by miscroscopic examination of the genitalia.
The moths are on wing from May to August depending on the location. The larvae feed on various mosses and grasses, including Rhytidiadelphus squarrosus, Syntrichia ruraliformis, Hypnum jutlandicum, Calliergonella cuspidata and Agrostis capillaris. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Cinerous Neb is recorded against all the insects logged in Liverpool (15 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
