Rare
Under 5% of wildlife watchers report a Valgus hemipterus sighting in Montreal on a given day, based on 17 verified sightings from GBIF citizen-science data. It is the 412th most-seen of the 926 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.
June and December
In those months about 10% of wildlife watchers report a Valgus hemipterus in Montreal on a given day, against under 5% in January–May and July–November, 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.
27th of 29
Of the 29 cities where we can rate Valgus hemipterus sightings, Montreal ranks 27th at under 5%. The best odds are in Kharkiv (Ukraine, about 20%), Kyiv (Ukraine, about 20%) and Sofia (Bulgaria, about 20%).
Same family: Scarabaeidae
The closest relatives of the Valgus hemipterus that you can see in Montreal (family Scarabaeidae, Scarabs) are Japanese Beetle (about 30%), Grapevine Beetle (about 10%) and Hermit Flower Beetle (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 Montreal (17 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.
