Rare
Under 5% of wildlife watchers report a Variable Narrow-Wing sighting in Mexico City on a given day, based on 21 verified sightings from GBIF citizen-science data. It is the 248th most-seen of the 557 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.
August and September
In those months about 10% of wildlife watchers report a Variable Narrow-Wing in Mexico City on a given day, against under 5% in October to July, the lowest months. Those are among Mexico City's wettest months, with about 150 mm of rain a month against 5 mm in December.
Between midnight and 3 am
Across all the parks we cover, that three-hour window holds the most Variable Narrow-Wing 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.

GBIF citizen-science records
It is estimated from how often the Variable Narrow-Wing is recorded against all the insects logged in Mexico City (21 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.
