Adscita statices, (also known as the forester and the green forester), is a day-flying moth of the family Zygaenidae. First described by the Swedish biologist Carl Linnaeus in 1758, it is found in Asia and Europe. The wingspan is 25–28 millimetres (0.98–1.10 in). The antennae, head, thorax, legs and abdomen are shiny green (the thorax is occasionally blue green and shimmering). However, the wings may appear rusty-red in the early morning and evening. The wide forewings are less glossy than the body, mostly blue green, sometimes also green to yellow green. The fringes are blackish grey. The hindwings are moderately wide with a slightly truncated rim, They are slightly transparent, blackish grey and lightened basally. The underside of both pairs of wings is grey. The caterpillars are pale yellowish-green with a central dark stripe and fine white hairs dorsally.
The wings of the green forester contain two types of colored scales, of which one contains pores of different sizes. These pores are able to fill with water, which causes the color of the scales to change from green to rusty-red.
The moth flies in sunshine from mid-May to early August. Ovum Eggs... Wikipedia →

Rare
Under 5% of wildlife watchers report a Green Forester Moth sighting in Wadden Sea National Park on a given day, based on 10 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 422nd most-seen of the 818 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
June
In that month about 10% of wildlife watchers report a Green Forester Moth in Wadden Sea National Park on a given day, against under 5% in July to May, the lowest months.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Green Forester Moth sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
4th of 4
Of the 4 parks where we can rate Green Forester Moth sightings, Wadden Sea National Park ranks 4th at under 5%. The best odds are in Białowieża National Park (Poland, about 10%), Sierra de Guadarrama National Park (Spain, about 10%) and Bavarian Forest National Park (Germany, under 5%).
GBIF citizen-science records
It is estimated from how often the Green Forester Moth is recorded against all the insects logged in Wadden Sea National Park (10 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.
