Diaphania costata
In 3 days ~10% in a week ~20%
Diaphania costata, the orange-shouldered sherbet moth or erroneously the white palpita moth, is a moth of the family Crambidae. The species was first described by Fabricius in 1775. It is frequently misidentified but may be widely dispersed in the Americas, perhaps only more recently in the southeastern US, with early records from Texas and Louisiana, possibly having been introduced accidentally, then range spreading in association with ornamental plants.
It is a small moth (less than 20 mm wingspan) with translucent white wings, and a gold line on the front edge of the forewing. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Orange-Shouldered Sherbet Moth is recorded against all the insects logged in Dallas (37 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.
