Rare
Under 5% of wildlife watchers report a Variable Narrow-Wing sighting in Houston on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 790th most-seen of the 1057 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 Variable Narrow-Wing in Houston 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 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.
9th of 10
Of the 10 cities where we can rate Variable Narrow-Wing sightings, Houston ranks 9th at under 5%. The best odds are in Austin (United States, about 10%), Monterrey (México, about 10%) and Boston (United States, under 5%).
Same family: Noctuidae
The closest relatives of the Variable Narrow-Wing that you can see in Houston (family Noctuidae, Cutworm Moths and Allies) are Wedgling Moth (about 10%), Yellow-Striped Armyworm Moth (about 10%) and Green Cutworm Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Variable Narrow-Wing is recorded against all the insects logged in Houston (8 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.
