Rare
Under 5% of wildlife watchers report a Waved Umber sighting in Lisbon on a given day, based on 16 verified sightings from GBIF citizen-science data. It is the 232nd most-seen of the 441 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.
May and November
In those months about 10% of wildlife watchers report a Waved Umber in Lisbon on a given day, against under 5% in June–October and December–April, the lowest months.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most Waved Umber 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.
4th of 4
Of the 4 cities where we can rate Waved Umber sightings, Lisbon ranks 4th at under 5%. The best odds are in Porto (Portugal, about 10%), Birmingham (United Kingdom, about 10%) and London (United Kingdom, under 5%).
GBIF citizen-science records
It is estimated from how often the Waved Umber is recorded against all the insects logged in Lisbon (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.
