Rare
Under 5% of wildlife watchers report a Red-Shouldered Pine Borer sighting in Portland on a given day, based on 16 verified sightings from GBIF citizen-science data. It is the 259th most-seen of the 507 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 Red-Shouldered Pine Borer in Portland on a given day, against under 5% in September to June, the lowest months. Those are among Portland's driest months, with about 15 mm of rain a month against 250 mm in December.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Red-Shouldered Pine Borer sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 3 cities where we can rate Red-Shouldered Pine Borer sightings, Portland has the highest daily chance: under 5%. Next come Toronto (Canada, under 5%) and Montreal (Canada, under 5%).
Same family: Cerambycidae
The closest relatives of the Red-Shouldered Pine Borer that you can see in Portland (family Cerambycidae, Longhorn Beetles) are Banded Alder Borer (about 10%), Xestoleptura crassipes (about 10%) and Locust Borer (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Red-Shouldered Pine Borer is recorded against all the insects logged in Portland (16 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.
