The v-pug (Chloroclystis v-ata) is a moth of the family Geometridae. It is found throughout the Palearctic region, the Near East and North Africa. It is well distributed in the British Isles except for the north of Scotland. The species was first described by Adrian Hardy Haworth in 1809.
The forewings of newly emerged adults are green with a characteristic V-shaped black mark which is part of a crossline. The green colouring fades over time but the markings, small size (14–19 mm (0.55–0.75 in)) and triangular resting posture make this an easy species to identify. The hindwings are greyish white.
Either one or two broods are produced each year and adults can be seen at any time between May and August. The species flies at night and is attracted to light. The green larva, usually with three reddish stripes, feeds on the flowers of a wide range of plants (see list below). The species overwinters as a pupa. Wikipedia →

With luck
About 10% of wildlife watchers report a V-Pug sighting in Porto on a given day, based on 130 verified sightings from GBIF citizen-science data. It is the 48th most-seen of the 498 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
April to July
In those months about 20% of wildlife watchers report a V-Pug in Porto on a given day, against under 5% in September to January, the lowest months. Those are among Porto's driest months, with about 50 mm of rain a month against 140 mm in January.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most V-Pug sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.

The closest relatives of the V-Pug that you can see in Porto (family Geometridae, Geometer Moths) are Double-Striped Pug (about 20%), Vestal (about 20%) and Pale Oak Beauty (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the V-Pug is recorded against all the insects logged in Porto (130 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.
