Harpalus rufipes
In 3 days ~20% in a week ~30%
Harpalus rufipes, commonly known as the strawberry seed beetle, is a species of ground beetle in the subfamily Harpalinae. It was described by Degeer in 1774, with the epithet rufipes being derived from Latin for red-footed. Harpalus rufipes is native to Europe.
As a predator, Harpalus rufipes is used as a biological agent to control seed-eating pests including aphids and slugs such as Deroceras reticulatum, though they are known to feed on the seeds of strawberries. It has been used as a model organism to investigate the immune system of beetles, and a study has shown it is sensitive to engine oil and diesel oil. Wikipedia →

With luck
About 10% of wildlife watchers report a Strawberry Seed Beetle sighting in Montreal on a given day, based on 70 verified sightings from GBIF citizen-science data. It is the 147th most-seen of the 926 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
July–August and December
In those months about 10% of wildlife watchers report a Strawberry Seed Beetle in Montreal on a given day, against under 5% in January–June and September–November, the lowest months.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most Strawberry Seed Beetle sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
Among the best
Of the 21 cities where we can rate Strawberry Seed Beetle sightings, Montreal ranks 7th at about 10%, level with the leaders once rounded. The best odds are in Kharkiv (Ukraine, about 10%), Belgrade (Serbia, about 10%) and Kyiv (Ukraine, about 10%).
GBIF citizen-science records
It is estimated from how often the Strawberry Seed Beetle is recorded against all the insects logged in Montreal (70 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.
