Rare
Under 5% of wildlife watchers report a Texas Systena sighting in Houston on a given day, based on 27 verified sightings from GBIF citizen-science data. It is the 384th most-seen of the 1057 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.
July and September

Of the 3 cities where we can rate Texas Systena sightings, Houston has the highest daily chance: under 5%. Next come Dallas (United States, under 5%) and Austin (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Texas Systena is recorded against all the insects logged in Houston (27 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.
