With luck
About 10% of wildlife watchers report a Fir Tussock Moth sighting in Houston on a given day, based on 181 verified sightings from GBIF citizen-science data. It is the 98th most-seen of the 1057 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Fir Tussock Moth is recorded against all the insects logged in Houston (181 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.
