In 3 days ~20% in a week ~40%
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.

GBIF citizen-science records
It is estimated from how often the Thirteen-Spotted Lady Beetle is recorded against all the insects logged in Edmonton (36 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.
