Rare
Under 5% of wildlife watchers report a Metallic Harpalus sighting in Vancouver on a given day, based on 42 verified sightings from GBIF citizen-science data. It is the 135th most-seen of the 482 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
May
In that month about 10% of wildlife watchers report a Metallic Harpalus in Vancouver on a given day, against under 5% in June to April, the lowest months. That is one of Vancouver's driest months, with about 60 mm of rain against 210 mm in November.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Metallic Harpalus sightings with a recorded time, and about half of them come between 6 pm and 6 am: it is seen both by day and at night.
7th of 25
Of the 25 cities where we can rate Metallic Harpalus sightings, Vancouver ranks 7th at under 5%. The best odds are in Kyiv (Ukraine, about 10%), Prague (Czechia, under 5%) and London (United Kingdom, under 5%).
Same family: Carabidae
The closest relatives of the Metallic Harpalus that you can see in Vancouver (family Carabidae, Ground Beetles) are Bronze Ground Beetle (about 10%), Narrow-Collared Snail-Eating Beetle (about 10%) and European Gazelle Beetle (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Metallic Harpalus is recorded against all the insects logged in Vancouver (42 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.
