Agriopis marginaria
In 3 days ~10% in a week ~20%
The dotted border (Agriopis marginaria) is a moth of the family Geometridae. The species was first described by Johan Christian Fabricius in 1776. It is found throughout Europe (except the far north), and the Near East. The female of this species has only vestigial wings and is totally flightless. It is usually found resting on the trunks and branches of the larval food plants. The male has orange-brown forewings ( less orange than in aurantiaria with a paler yellowish band and a row of dots along the termen which gives it its common name. The hindwings are whitish with faint fascia. Melanic forms are frequently seen. The wingspan is 36–42 mm.
The adults are active from February to April[1], the male sometimes coming to light but not strongly attracted. The egg is ovate, greenish, becoming reddish on the upper side. The very variable larva is usually greenish-brown with dark cross-shaped markings along the back and feeds on a range of trees and shrubs (see list below). The species overwinters as a pupa.

Rare
Under 5% of wildlife watchers report a Dotted Border Moth sighting in Munich on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 392nd most-seen of the 521 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.
February and March
In those months about 10% of wildlife watchers report a Dotted Border Moth in Munich on a given day, against under 5% in April to January, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Dotted Border Moth sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
14th of 15
Of the 15 cities where we can rate Dotted Border Moth sightings, Munich ranks 14th at under 5%. The best odds are in Liverpool (United Kingdom, about 10%), Porto (Portugal, about 10%) and Prague (Czechia, about 10%).
Same family: Geometridae
The closest relatives of the Dotted Border Moth that you can see in Munich (family Geometridae, Geometer Moths) are Small Dusty Wave (about 10%), Winter Moth (about 10%) and Yellow Shell Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Dotted Border Moth is recorded against all the insects logged in Munich (6 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.
