In 3 days ~10% in a week ~20%
Nematopogon adansoniella is a lepidopteran, a moth of the family Adelidae. It is found in Europe. Its wingspan is 15–20 mm. The moth flies from late April to June depending on the location. The larvae feed on Fagus sylvatica, oak, Prunus spinosa and bilberry.
The synonym Tinea panzerella has also been applied to Pseudatemelia subochreella in error. To certainly determine the species of the genus Nematopogon dissection and study of the genitalia is necessary. This is a small, rather primitive moth, with wing venation that is heteroneurous and a female reproductive system with a single opening used both for mating and for oviposition.
A tergosternal connection can be observed, posterior to the first abdominal spiracle, formed by a ventrocaudal process of the first tergite that connects to the anterolateral extension of the second sternite. The forewing is lanceolate with a rounded apex; it is dull brownish-grey with greenish iridescence and strongly marked veins; the termen tends to be slightly darker. Microtrichia are present and uniformly distributed.
Its hindwing is stouter and more rounded, a uniform off-white with silvery reflections; as in all Adelidae... Wikipedia →

Rare
Under 5% of wildlife watchers report a Nematopogon adansoniella sighting in Pyrénées National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 1144th most-seen of the 1277 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
April and May
In those months about 10% of wildlife watchers report a Nematopogon adansoniella in Pyrénées National Park on a given day, against under 5% in June to March, the lowest months.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Nematopogon adansoniella sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
Only Pyrénées National Park, in our data
Pyrénées National Park is the only park on Wallace's Line with enough records to rate Nematopogon adansoniella sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Adelidae
The closest relatives of the Nematopogon adansoniella that you can see in Pyrénées National Park (family Adelidae, Fairy Moths) are Adela viridella (about 10%) and Adela australis (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Nematopogon adansoniella is recorded against all the insects logged in Pyrénées National Park (5 verified sightings from 2019 to 2026), 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.
