The longhorn moth or yellow-barred long-horn (Nemophora degeerella) is a diurnal lepidopteran from the moths family Adelidae (fairy longhorn moths). This species is present on most of Europe, but it is fairly common in north west Europe. The habitat of these moths is damp deciduous forests with wooded lanes and hedgerows.
The wingspan of Nemophora degeerella ranges from 18–20 millimetres (0.71–0.79 in) in males, from 15–18 millimetres (0.59–0.71 in) in females. The head is dark brown, with dark and yellow hair-like scales. The thorax has a bronzy golden shining. Forewings are shiny bronzy golden yellow or shiny ochreous with longitudinal dark brown and lead-gray blueish-violet shining streaks. A yellow transversal band cross the whole forewings, framed by two lead-gray blueish-violet shining stripes with a dark brown border. The three longitudinal lead-gray, blueish-violet shining stripes situated in the basal part of the wings do not treach the transversal fascia. Rear wings are brownish gray.
The longhorn moth males have filiform antennae ranging up to five times their body length, while the female has much shorter antennae. Moreover... Wikipedia →

With luck
About 10% of wildlife watchers report a Yellow-Barred Longhorn sighting in Manchester on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 263rd most-seen of the 458 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
May and June
In those months about 10% of wildlife watchers report a Yellow-Barred Longhorn in Manchester on a given day, against under 5% in July to April, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Yellow-Barred Longhorn sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 17 cities where we can rate Yellow-Barred Longhorn sightings, Manchester ranks 8th at about 10%, level with the leaders once rounded. The best odds are in Leeds (United Kingdom, about 10%), Birmingham (United Kingdom, about 10%) and London (United Kingdom, about 10%).
GBIF citizen-science records
It is estimated from how often the Yellow-Barred Longhorn is recorded against all the insects logged in Manchester (13 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.
