With luck
About 10% of wildlife watchers report a Sacken Longhorn Robber sighting in Seattle on a given day, based on 74 verified sightings from GBIF citizen-science data. It is the 95th most-seen of the 428 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
June and July
In those months about 10% of wildlife watchers report a Sacken Longhorn Robber in Seattle on a given day, against under 5% in August to May, the lowest months. Those are among Seattle's driest months, with about 35 mm of rain a month against 190 mm in November.
Among the best
Of the 3 cities where we can rate Sacken Longhorn Robber sightings, Seattle ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Vancouver (Canada, about 10%).
GBIF citizen-science records
It is estimated from how often the Sacken Longhorn Robber is recorded against all the insects logged in Seattle (74 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.
