Thera variata, the spruce carpet, is a moth of the family Geometridae. It is found throughout Europe, North Asia and Japan. The common name spruce carpet is also used when referring to Thera britannica. The length of the forewings is 13–17 mm. The forewings are light ochreous-brown, sprinkled with dark fuscous with an ochreous-brown basal patch the edge waved, right-angled above middle. The median band is ochreous-brown or dark fuscous, black-marked on veins, edges dark fuscous, sometimes whitish-margined its anterior angulated in middle and its posterior waved, right-angled above middle. There is a black discal mark, a subterminal line obscurely whitish and a cloudy darker apical dash. The hindwings are pale fuscous, ochreous tinged with a darker discal dot and sometimes a curved postmedian line. The larva is blue-green; dorsal line darker, pale edged; subdorsal yellowish-white, posteriorly yellow; subspiracular yellowish-white; segment 13 with two points. Wikipedia →

With luck
About 10% of wildlife watchers report a Thera variata 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.
April–May and August–September
In those months about 10% of wildlife watchers report a Thera variata in Bavarian Forest National Park on a given day, against under 5% in June–July and October–March, the lowest months.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most Thera variata sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
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 Thera variata sightings: about 10% of wildlife watchers there report one on a given day.
Same family: Geometridae
The closest relatives of the Thera variata that you can see in Bavarian Forest National Park (family Geometridae, Geometer Moths) are Common Heath (about 20%), Latticed Heath (about 20%) and Yellow Shell Moth (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Thera variata 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.
