Rare
Under 5% of wildlife watchers report a Dingy Shears sighting in London on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 1394th 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 Dingy Shears 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 Dingy Shears 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.
2nd of 2
Of the 2 cities where we can rate Dingy Shears sightings, London ranks 2nd at under 5%. The best odds are in Liverpool (United Kingdom, about 10%).
Same family: Noctuidae
The closest relatives of the Dingy Shears that you can see in London (family Noctuidae, Cutworm Moths and Allies) are Large Yellow Underwing (about 30%), Heart And Dart (about 20%) and Shuttle-Shaped Dart (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Dingy Shears is recorded against all the insects logged in London (6 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.
