Rare
Under 5% of wildlife watchers report an Arrowhead Borer sighting in Houston on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 603rd 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.
May
In that month about 10% of wildlife watchers report an Arrowhead Borer in Houston on a given day, against under 5% in June to April, the lowest months.
Only Houston, in our data
Houston is the only city on Wallace's Line with enough records to rate Arrowhead Borer sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Arrowhead Borer is recorded against all the insects logged in Houston (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.
