In 3 days ~10% in a week ~20%
Ethmia bittenella is a moth in the family Depressariidae. It is found in the United States from southern Texas to southern and central Mexico (Chiapas and Guerrero) and then northward along the west coast to Sinaloa and Sonora. It is also found in north-western Costa Rica.
The length of the forewings is 7.4–9.6 mm (0.29–0.38 in). The ground color of the forewings is white with blackish brown markings, those longitudinally through the middle of the wing are reflecting metallic blue. The ground color of the hindwings is whitish basally, becoming pale brownish on the apical half. Adults are on wing in February, March, May, June and November (in Texas) and from late June to August (in Sonora and Sinaloa).
The larvae possibly feed on Ehretia anacua. Pupae were collected in galleries in stems of Pseudabutilon lozani, which probably represents a pupation site only. Wikipedia →

Rare
Under 5% of wildlife watchers report an Ethmia bittenella sighting in Austin on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 1145th most-seen of the 1624 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 an Ethmia bittenella in Austin on a given day, so our monthly data shows no clear season.
Only Austin, in our data

GBIF citizen-science records
It is estimated from how often the Ethmia bittenella is recorded against all the insects logged in Austin (10 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.
