In 3 days ~10% in a week ~20%
Ogdoconta tacna is a moth in the family Noctuidae first described by William Barnes in 1904. It is found in the US in central and south-eastern Texas. It is probably also present in Mexico. The length of the forewings is 11–13.5 mm. The forewings are gray brown with a slight greenish tint with a pattern of fine white lines and a light scattering of white scales. The orbicular and reniform spots are clearly outlined by fine, dirty-white lines. The postmedial line is mostly straight and oblique from the costa to the posterior margin, although there is a slight outward pointing angulation near the bottom of the reniform spot. The postmedial line is accented with vague dark gray-green rectangles on its inner side. The subterminal area is slightly lighter than the terminal area, and the subterminal line is irregular and dull white. The terminal line consists of a series of dark rectangles accented on their inner sides by white lines. The hindwing of the male is dirty white with dark scales along the fringe and a dusting of dark scales along the costal margin. The female hindwing is more generally suffused with dark scales. Adults have been recorded on wing in April and May and again in September and October. Wikipedia →

Rare
Under 5% of wildlife watchers report an Ogdoconta tacna sighting in Austin on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 1106th 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 Ogdoconta tacna in Austin on a given day, so our monthly data shows no clear season.
Only Austin, in our data
Austin is the only city on Wallace's Line with enough records to rate Ogdoconta tacna sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Ogdoconta tacna is recorded against all the insects logged in Austin (13 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.
