Rare
Under 5% of wildlife watchers report a Northern Herpetogramma sighting in Seattle on a given day, based on 27 verified sightings from GBIF citizen-science data. It is the 169th 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.
July and August
In those months about 10% of wildlife watchers report a Northern Herpetogramma in Seattle on a given day, against under 5% in September to June, the lowest months. Those are among Seattle's driest months, with about 25 mm of rain a month against 190 mm in November.

Of the 2 cities where we can rate Northern Herpetogramma sightings, Seattle has the highest daily chance: under 5%. Next come Toronto (Canada, under 5%).
GBIF citizen-science records
It is estimated from how often the Northern Herpetogramma is recorded against all the insects logged in Seattle (27 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.
