Agriphila geniculea, the elbow-striped grass-veneer, is a species of moth of the family Crambidae. It was first described by Adrian Hardy Haworth in 1811. This species can be found in most of Europe and parts of North Africa. It usually occurs in dry pastures, grassy area, sand-dunes, gardens and grassland. The wingspan is 20–26 mm. The forewings usually show two strongly curved cross-lines, but sometimes these lines are not visible.
This species is very similar to Agriphila tolli and Agriphila inquinatella. It can be distinguished from the first on the basis of the higher distance that separates said cross-lines. Moreover, in A. geniculea the forewings are crossed by a couple of chevrons, while A. inquinatella is longitudinally variably streaked.
The species has one generation. The moth flies at dusk from July to October depending on the location. When disturbed they come to light. The larvae can be found from late September to early... Wikipedia →

With luck
About 10% of wildlife watchers report an Elbow-Striped Grass-Veneer sighting in London on a given day, based on 209 verified sightings from GBIF citizen-science data. It is the 192nd most-seen of the 1504 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
August
In that month about 30% of wildlife watchers report an Elbow-Striped Grass-Veneer in London on a given day, against under 5% in October to July, the lowest months.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Elbow-Striped Grass-Veneer sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
Among the best
Of the 13 cities where we can rate Elbow-Striped Grass-Veneer sightings, London ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Liverpool (United Kingdom, about 10%).
Same genus: Agriphila
The closest relatives of the Elbow-Striped Grass-Veneer that you can see in London (genus Agriphila) are Pearl Veneer (about 10%) and Common Grass-Veneer (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Elbow-Striped Grass-Veneer is recorded against all the insects logged in London (209 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.
