Rare
Under 5% of wildlife watchers report a Chocolate-Tip sighting in Porto on a given day, based on 14 verified sightings from GBIF citizen-science data. It is the 283rd 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 30%, if each day is a fresh chance.
April and August–September
In those months about 10% of wildlife watchers report a Chocolate-Tip in Porto on a given day, against under 5% in May–July and October–March, the lowest months.
Between 5 and 8 am
Across all the parks we cover, that three-hour window holds the most Chocolate-Tip sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 3 cities where we can rate Chocolate-Tip sightings, Porto has the highest daily chance: under 5%. Next come Liverpool (United Kingdom, under 5%) and London (United Kingdom, under 5%).
GBIF citizen-science records
It is estimated from how often the Chocolate-Tip is recorded against all the insects logged in Porto (14 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.
