With luck
About 10% of wildlife watchers report a Buff-Tip sighting in Porto on a given day, based on 92 verified sightings from GBIF citizen-science data. It is the 58th most-seen of the 498 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
June to August
In those months about 20% of wildlife watchers report a Buff-Tip in Porto on a given day, against under 5% in October and December–March, the lowest months. Those are among Porto's driest months, with about 20 mm of rain a month against 140 mm in January.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Buff-Tip sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
Yes
Of the 21 cities where we can rate Buff-Tip sightings, Porto has the highest daily chance: about 10%. Next come London (United Kingdom, about 10%) and Manchester (United Kingdom, about 10%).
Same family: Notodontidae
The closest relatives of the Buff-Tip that you can see in Porto (family Notodontidae, Prominent Moths) are Oak Marbled Brown (about 10%), Swallow Prominent (about 10%) and Pale Prominent (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Buff-Tip is recorded against all the insects logged in Porto (92 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.
