Pelurga comitata, the dark spinach, is a moth of the family Geometridae. It is found throughout the Palearctic, including Europe (except the South-west and the Arctic Region), Siberia, the Russian Far East and northern China
The wingspan is 25–30 mm. The length of the forewings is 16–18 mm. The forewings have a yellow-brown ground colour. The basal field is darker brownish. The midfield is wide, intersected by several lines and has a dark band on the inside. The basic colour of the forewings varies only slightly, in the tints of pale and dark browns. The outside of the midfield is bordered by a dark cross line with a pronounced bend distad. The wing apex is divided by a dark bar. The paler marginal field is marked with a faint wavy line that is shaded on the inside by brownish stains. The hind wings are yellowish grey and have indistinct crossbars.
In ab. ferruginascens Krulik. [the ground colour] becomes bright rust-reddish. - In ab. moldavinata Carad. It is much darker and more unicolorous, the hindwing is also darkened. This latter form, which is recorded from N. Germany, Romnania, the Ural, Ussuri, etc., is perhaps in some localities tending to form a local race. — ab. zonata Wahhgren has the median band entirely brown-black, ground colour normal.
The larva is stout, rugose laterally, segmentation distinct; ochreous brown; dorsum tinged with green and with a row of large V-shaped dark markings on the abdominal segments, pointing forward. The moth flies from mid June to mid September [1].
The larva feeds on orache and goosefoot especially on the flowers and seeds. Wikipedia →

Rare
Under 5% of wildlife watchers report a Dark Spinach sighting in Saint Petersburg on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 248th most-seen of the 448 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.
August
In that month about 10% of wildlife watchers report a Dark Spinach in Saint Petersburg on a given day, against under 5% in September to July, the lowest months. That is one of Saint Petersburg's wettest months, with about 100 mm of rain against 40 mm in February.
Between midnight and 3 am
Across all the parks we cover, that three-hour window holds the most Dark Spinach 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.
12th of 12
Of the 12 cities where we can rate Dark Spinach sightings, Saint Petersburg ranks 12th at under 5%. The best odds are in Kharkiv (Ukraine, about 10%), Nizhny Novgorod (Russia, about 10%) and Kyiv (Ukraine, about 10%).
GBIF citizen-science records
It is estimated from how often the Dark Spinach is recorded against all the insects logged in Saint Petersburg (10 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.
