|Wikispecies has information related to: Thirteen-spotted 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 the northern hemisphere. It can be found in farm fields, grasslands, wetlands, and parks. In North America, it can be found in Canada and the northern United States. The relative abundance of this species in North America has been associated with the introduction of the non-native coccinellid Coccinella septempunctata.
