Rare
Under 5% of wildlife watchers report a Valgus hemipterus sighting in Lisbon on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 361st 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Valgus hemipterus in Lisbon on a given day, so our monthly data shows no clear season.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Valgus hemipterus sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
28th of 29
Of the 29 cities where we can rate Valgus hemipterus sightings, Lisbon ranks 28th at under 5%. The best odds are in Kharkiv (Ukraine, about 20%), Kyiv (Ukraine, about 20%) and Sofia (Bulgaria, about 20%).
Same family: Scarabaeidae

GBIF citizen-science records
It is estimated from how often the Valgus hemipterus is recorded against all the insects logged in Lisbon (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.
