In 3 days ~10% in a week ~30%
Hippodamia tredecimpunctata, commonly known as the thirteen-spot ladybeetle, is a species of lady beetle. Adult H. tredecimpunctata have domed backs, mainly oval, often shiny with short legs and antennae. They have two wing covers. They are usually red to orange in color. This species has thirteen dark or black spots. The larvae are slightly flattened and covered with miniature spines. Very small eggs are laid in groups of 10–50 on the undersides of leaves.
The species is distributed throughout much of the northern hemisphere - Europe, North Africa, European Russia, the Caucasus, Siberia, the Russian Far East, Belarus, Ukraine, Moldova, Transcaucasia, Kazakhstan, Middle Asia, Western Asia, Afghanistan, Mongolia, China, the Korean Peninsula, Japan, and North America. In North America, it can be found in Canada and the northern United States. The relative abundance of this species has decreased in many regions (midwestern US, Maine, Quebec, and New Brunswick) following the introduction of the non-native ladybeetle Coccinella septempunctata. On the other hand, H. tredecimpunctata appears to coexist with non-native ladybeetles in Manitoba and Ontario.

Rare
Under 5% of wildlife watchers report a Thirteen-Spotted Lady Beetle sighting in Calgary on a given day, based on 29 verified sightings from GBIF citizen-science data. It is the 86th most-seen of the 256 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–June and September
In those months about 10% of wildlife watchers report a Thirteen-Spotted Lady Beetle in Calgary on a given day, against under 5% in July–August and October–April, the lowest months. Those are among Calgary's wettest months, with about 80 mm of rain a month against 15 mm in January.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Thirteen-Spotted Lady Beetle sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
6th of 14
Of the 14 cities where we can rate Thirteen-Spotted Lady Beetle sightings, Calgary ranks 6th at under 5%. The best odds are in Novosibirsk (Russia, about 10%), Edmonton (Canada, about 10%) and Helsinki (Finland, about 10%).
GBIF citizen-science records
It is estimated from how often the Thirteen-Spotted Lady Beetle is recorded against all the insects logged in Calgary (29 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.
