Adela croesella
In 3 days ~10%
Adela croesella is a moth of the family Adelidae. It is found in most of Europe. The wingspan is 11–14 mm. The head is ferruginous mixed with black. The antennae in male 2.5 [the length of the forewing], black, the tip white; in female hardly 1.5, thickened with violet-black scales to above middle, remainder white. The forewings are shining dark violet fuscous, more or less streaked suffusely between veins with golden-ochreous with a straight deep yellow fascia close beyond middle, narrower costally, edged first with dark fuscous and then with narrow violet fasciae. The hindwings are dark purplish fuscous.
Adults are on wing from late May to June. They are on wing during the day in sunshine and visit flowers. [14.7 x 21.2 cm] At first, the larvae probably feed on flowers of Hippophae rhamnoides or Ligustrum vulgare. Older larvae built a portable case from leaf fragments and particles of soil and feed on fallen leaves. Wikipedia →

Rare
Under 5% of wildlife watchers report a Small Barred Longhorn sighting in Moscow on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 841st most-seen of the 1111 insects we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Small Barred Longhorn in Moscow on a given day, so our monthly data shows no clear season.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Small Barred Longhorn sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 2 cities where we can rate Small Barred Longhorn sightings, Moscow ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Vienna (Austria, under 5%).
GBIF citizen-science records
It is estimated from how often the Small Barred Longhorn is recorded against all the insects logged in Moscow (7 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.
