Trichopteryx carpinata, the early tooth-striped, is a moth of the family Geometridae. The species was first described by Moritz Balthasar Borkhausen in 1794. It is found in most of Europe (except Iceland, Greece, Sicily, Sardinia and Croatia), east to the eastern Palearctic realm including the Russian Far East, Siberia, and the Ile District, Kazakhstan.
The wingspan is 30–34 mm. "Ground-colour whitish grey, in freshly emerged specimens with a very delicate green tinge; the markings somewhat darker brownish grey, but generally quite weakly expressed. Hindwing whitish, greyer distally, sometimes with one or two fairly well-defined grey lines not far from the distal margin, Male narrower-winged than female. — In ab. fasciata Prout the two central bands are very much darker, sometimes quite deep fuscous, giving the effect of a different species. Frequent in Perthshire. - obscurata Sp. Schneid., described as a local race in Norway, is perhaps transitional towards ab. fasciata, as the bands and lines are said to be more distinct; the ground-colour, however, is also darkened, which is not the case with fasciata. - ab. unifasciata Rbl. is a development of ab. fasciata in which the two bands coalesce in their posterior part, leaving only a pale central part anteriorly, as in polycommata."
The larva is naked, green with narrow white longitudinal stripes. Adults are on wing from April to May. There is one generation per year. The larvae feed on various trees, including the trees Lonicera, Salix and Betula. Wikipedia →

With luck
About 10% of wildlife watchers report an Early Tooth-Striped sighting in Cairngorms National Park on a given day, based on 15 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 133rd most-seen of the 300 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
April
In that month about 40% of wildlife watchers report an Early Tooth-Striped in Cairngorms National Park on a given day, against under 5% in June to February, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Early Tooth-Striped 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 parks where we can rate Early Tooth-Striped sightings, Cairngorms National Park ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Snowdonia National Park (United Kingdom, about 10%).
Same family: Geometridae
The closest relatives of the Early Tooth-Striped that you can see in Cairngorms National Park (family Geometridae, Geometer Moths) are Chimney-Sweeper (about 20%), Bordered White (about 20%) and Common Heath (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Early Tooth-Striped is recorded against all the insects logged in Cairngorms National Park (15 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.
