Rare
Under 5% of wildlife watchers report a New House Borer sighting in Seattle on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 380th most-seen of the 428 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.
August
In that month about 10% of wildlife watchers report a New House Borer in Seattle on a given day, against under 5% in September to July, the lowest months. That is one of Seattle's driest months, with about 30 mm of rain against 190 mm in November.
Among the best
Of the 3 cities where we can rate New House Borer sightings, Seattle ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Portland (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the New House Borer is recorded against all the insects logged in Seattle (5 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.
