Adela croesella
In 3 days ~20% in a week ~30%
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 →

With luck
About 10% of wildlife watchers report a Small Barred Longhorn sighting in Bavarian Forest National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 661st most-seen of the 1115 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 Small Barred Longhorn in Bavarian Forest National Park on a given day, against under 5% in July to April, the lowest months.
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.
Only Bavarian Forest National Park, in our data
Bavarian Forest National Park is the only park on Wallace's Line with enough records to rate Small Barred Longhorn sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Small Barred Longhorn is recorded against all the insects logged in Bavarian Forest National Park (8 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.
