In 3 days ~10% in a week ~20%
Cochylimorpha straminea, the straw conch, is a species of moth of the family Tortricidae. It is found in most of Europe, Morocco, Algeria, Tunisia, Asia Minor, the Palestinian territories, Iraq, Syria, Armenia, Transcaspia, Turkmenistan and Iran (the Elburz Mountains).
The wingspan is 13–21 mm. The costa of the forewings is almost straight. The ground colour is whitish-ochreous, clouded and strigulated with darker and a few dark fuscous scales on costa. There is an ochreous-brown streak from the dorsum before the middle and parallel to the termen, reaching rather more than half across the wing. There is a fuscous dorsal dot before the tornus and a brownish terminal line. The hind wings are rather light grey. The larva is whitish yellowish; head black; plate of 2 brown. Julius von Kennel provides a full description.
There are two generations per year, with adults on wing from May to July and again from late August to September. The larvae feed on Scabiosa, Artemisia and Centaurea species. Wikipedia →

Rare
Under 5% of wildlife watchers report a Straw Conch sighting in London on a given day, based on 5 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 Straw Conch in London on a given day, so our monthly data shows no clear season.
Only London, in our data
London is the only city on Wallace's Line with enough records to rate Straw Conch sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Tortricidae
The closest relatives of the Straw Conch that you can see in London (family Tortricidae, Tortricid Leafroller Moths) are Light Brown Apple Moth (about 20%), Common Marble (about 10%) and Clepsis dumicolana (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Straw Conch is recorded against all the insects logged in London (5 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.
