In 3 days ~20% in a week ~40%
Cydia latiferreana, the filbertworm moth, is a moth of the family Tortricidae. It was formerly (and sometimes is still) separated in a monotypic genus Melissopus. It is found in most of North America. The wingspan is about 18 mm. Adults are on wing from July to October depending on the location.
The larvae (filbertworms) feed on the acorns of Quercus alba (white oak), Quercus macrocarpa, Quercus rubra and Quercus velutina but are most noted for feeding on hazelnuts—seeds of the genus Corylus—and are a major pest of hazelnut orchards in the Pacific northwest. Wikipedia →

With luck
About 10% of wildlife watchers report a Filbertworm Moth sighting in Houston on a given day, based on 173 verified sightings from GBIF citizen-science data. It is the 98th most-seen of the 1057 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
October
In that month about 20% of wildlife watchers report a Filbertworm Moth in Houston on a given day, against under 5% in December to May, the lowest months.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Filbertworm Moth sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Among the best
Of the 16 cities where we can rate Filbertworm Moth sightings, Houston ranks 3rd at about 10%, level with the leaders once rounded. The best odds are in Austin (United States, about 10%) and Dallas (United States, about 10%).
GBIF citizen-science records
It is estimated from how often the Filbertworm Moth is recorded against all the insects logged in Houston (173 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.
