Rare
Under 5% of wildlife watchers report a Giant Grass-Veneer sighting in London on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 1300th most-seen of the 1504 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Giant Grass-Veneer in London on a given day, so our monthly data shows no clear season.
Between midnight and 3 am
Across all the parks we cover, that three-hour window holds the most Giant Grass-Veneer sightings with a recorded time, and about half of them come between 6 am and 6 pm: it is most active around dawn and dusk.
Only London, in our data
London is the only city on Wallace's Line with enough records to rate Giant Grass-Veneer sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Crambidae
The closest relatives of the Giant Grass-Veneer that you can see in London (family Crambidae, Crambid Snout Moths) are Box Tree Moth (about 30%), Mint Moth (about 20%) and Garden Grass-Veneer (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Giant Grass-Veneer is recorded against all the insects logged in London (7 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.
