Possible
About 20% of wildlife watchers report a Valgus hemipterus sighting in Sofia on a given day, based on 15 verified sightings from GBIF citizen-science data. It is the 22nd most-seen of the 115 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
May
In that month about 30% of wildlife watchers report a Valgus hemipterus in Sofia on a given day, against under 5% in July to March, the lowest months.
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.
Among the best
Of the 29 cities where we can rate Valgus hemipterus sightings, Sofia ranks 3rd at about 20%, level with the leaders once rounded. The best odds are in Kharkiv (Ukraine, about 20%) and Kyiv (Ukraine, about 20%).
Same family: Scarabaeidae
The closest relatives of the Valgus hemipterus that you can see in Sofia (family Scarabaeidae, Scarabs) are European Rose Chafer (about 10%) and Holochelus aequinoctialis (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Valgus hemipterus is recorded against all the insects logged in Sofia (15 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.
