Rare
Under 5% of wildlife watchers report a Xylotrechus stebbingi sighting in Porto on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 422nd most-seen of the 498 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.
June and July
In those months about 10% of wildlife watchers report a Xylotrechus stebbingi in Porto on a given day, against under 5% in August to May, the lowest months. Those are among Porto's driest months, with about 25 mm of rain a month against 140 mm in January.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Xylotrechus stebbingi sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Only Porto, in our data
Porto is the only city on Wallace's Line with enough records to rate Xylotrechus stebbingi sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Xylotrechus stebbingi is recorded against all the insects logged in Porto (6 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.
