Cisthene tenuifascia, the thin-banded lichen moth or three-banded lichen moth, is a moth of the family Erebidae. It was described by Leon F. Harvey in 1875. It is found in Mexico and from Arizona to Florida, North Carolina and Oklahoma. Strays can be found further north.
The length of the forewings is 7–9 mm. Adults have a yellow-orange strip along the inner margin of the forewing. They are on wing from March to October and have been recorded sugaring on Baccharis sarothroides and Baccharis salicifolia.

Rare
Under 5% of wildlife watchers report a Thin-Banded Lichen Moth sighting in Saguaro National Park on a given day, based on 7 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 248th most-seen of the 354 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.
July and September–October
In those months about 10% of wildlife watchers report a Thin-Banded Lichen Moth in Saguaro National Park on a given day, against under 5% in August and November–June, the lowest months.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Thin-Banded Lichen Moth 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.
Only Saguaro National Park, in our data
Saguaro National Park is the only park on Wallace's Line with enough records to rate Thin-Banded Lichen Moth sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Thin-Banded Lichen Moth is recorded against all the insects logged in Saguaro National Park (7 verified sightings from 2019 to 2026), 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.
