Coccinella septempunctata, the common ladybug, the seven-spot ladybird (or, in North America, seven-spotted ladybug or "C-7" [1]), is a carnivorous beetle native to the Old World and is the most common ladybird in Europe. The beetle is also found in North America, Central and Eastern Asia and regions with a temperate climate.
The small, orange beetle belongs to same family as ladybugs but differs in a few key ways.
Ladybugs, despite the misleading “bug” in their name, don’t have these. Kudzu bugs are brownish-green with dark brown spots. They are about a quarter of an inch large.
Ladybugs don't shelter inside during the winter months, while lady beetles will. Lady beetles gather in large groups around warm, reflective surfaces like windows. Ladybugs do not do this.
Male–male competition in this fish species also selects for large size in males. There is aggressive competition by males over territory and access to larger shells. Large males win fights and steal shells from competitors.
Ladybugs aren't just cute little insects. They play a large role in our ecosystem. Here's what they eat and why you might want them in your yard.
