Epitheca petechialis
In 3 days ~10% in a week ~20%
The dot-winged baskettail (Epitheca petechialis) is a dragonfly of the family Corduliidae. Their flight season extends from January to July, slightly later than the other baskettails. The easiest specimens to identify are those with the characteristic spots on the hindwing that give the species its name.
Individuals without these spots are difficult to distinguish from the other species in this genus. The caudal appendages (structures at the tip of the abdomen) differ between the species and can be compared with known drawings or close-up photos. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Dot-Winged Baskettail is recorded against all the insects logged in Austin (23 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.
