Leptostales ferruminaria, the light-ribboned wave, is a moth of the family Geometridae. The species was first described by Philipp Christoph Zeller in 1872. It is found in North America, where it has been recorded from eastern North America west to Oklahoma and north to British Columbia.

Rare
Under 5% of wildlife watchers report a Light-Ribboned Wave sighting in Dallas on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 873rd most-seen of the 1412 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.
September
In that month about 10% of wildlife watchers report a Light-Ribboned Wave in Dallas on a given day, against under 5% in October to August, the lowest months.
Only Dallas, in our data
Dallas is the only city on Wallace's Line with enough records to rate Light-Ribboned Wave sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Light-Ribboned Wave is recorded against all the insects logged in Dallas (12 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.
