Rare
Under 5% of wildlife watchers report a Kirby's Backswimmer sighting in Vancouver on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 328th 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 20%, if each day is a fresh chance.
December
In that month about 10% of wildlife watchers report a Kirby's Backswimmer in Vancouver on a given day, against under 5% in January to November, the lowest months. That is one of Vancouver's wettest months, with about 180 mm of rain against 25 mm in July.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Kirby's Backswimmer sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 4 cities where we can rate Kirby's Backswimmer sightings, Vancouver ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in Portland (United States, under 5%) and Calgary (Canada, under 5%).
Same order: Hemiptera
The closest relatives of the Kirby's Backswimmer that you can see in Vancouver (order Hemiptera, True Bugs, Hoppers, Aphids, and allies) are Brown Marmorated Stink Bug (about 20%), Western Conifer Seed Bug (about 20%) and Bright-Spotted Groundbug (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Kirby's Backswimmer is recorded against all the insects logged in Vancouver (9 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.
