Rare
Under 5% of wildlife watchers report a Sand Chafer sighting in Houston on a given day, based on 26 verified sightings from GBIF citizen-science data. It is the 418th 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Sand Chafer in Houston on a given day, so our monthly data shows no clear season.
Only Houston, in our data
Houston is the only city on Wallace's Line with enough records to rate Sand Chafer sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Scarabaeidae
The closest relatives of the Sand Chafer that you can see in Houston (family Scarabaeidae, Scarabs) are Common Green June Beetle (about 10%) and Dark Flower Scarab (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Sand Chafer is recorded against all the insects logged in Houston (26 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.
