Ladybird (especially in Canada and the U.K.)
Explanation of Names
A group with many interesting biological, cultural, and linguistic associations:
Scientific name: from New Latin coccinella
, the diminutive of Latin coccinus
, "scarlet." That from Greek kokkinos
(κοκκινος), from kokkos
, "berry." A related Greek term is kermes
, an insect that was used to make a scarlet dye. Compare cochineal
, another red insect, and also the bacterium Coccus
, from the same root (Internet searches), (1)
Common name: "Ladybird" was first used in medieval England, perhaps because these beneficial predators of agricultural pests were believed to be a gift from the Virgin Mary
- the "Lady." Other European names have similar associations, such as the German Marienkafer
, "Marybeetle." This may represent an even older, widespread pre-Christian mythology associated with the beetle (Univ. Florida
, Internet searches).
A well-known use of the common name is the popular nursery rhyme Ladybird, Ladybird, fly away home...

Red lady beetles with black spots are among the most easily-recognized insects. There are many other colors and patterns, though, which can be hard to identify. The following physical features will identify all lady beetles, no matter what color they are.
Rounded or oval, dorsally convex (dome-shaped), nearly flat on the ventral (bottom)
Pronotum (hard shell in front of wings) often conceals the head from above, and may even look like a head. Photos show the same species with and without head concealed.
Antennae short or very short with 8-11 segments; last 3-6 segments form a weak club. Click the thumbnails for a close look at the details.
Tarsal formula 4-4-4, but appears to be 3-3-3. In other words, each lower leg appears to have three segments.
First abdominal sternite entire, not divided by hind coxae (characteristic of suborder Polyphaga
of the Coleoptera)
[key to genera and selected species in(14)
Larvae are very different-looking, and may not be recognized as lady beetles. They are soft-bodied, flattened and elongated ("alligator-shaped"). Predatory species have fully-developed legs, so they don't look as much like worms as many other beetle larvae. Larvae go through 4 instars
, that is they molt three times before pupating; the instars can be fairly different. Many are gray or black and may have colorful markings (A). Others have waxy white tufts, resembling caterpillars or mealybugs (B). Plant-eating larvae are yellow with long spines (C).
Worldwide, including all of North America.
Anywhere with suitable food. Usually outdoors, but in cold weather large groups may enter houses.
Active adults and larvae are present from spring to fall. Some adults can survive cold winters, but are usually inactive. All life stages present year-round in the south.
Most lady beetles are predatory, eating a wide variety of other insects. Prey includes aphids (A, B), mealybugs, scale insects, fly larvae (C), and small caterpillars. They also eat insect eggs (D) and pupae (E) - even those of other lady beetles (F).
Some lady beetles are plant-eating, however, and can be destructive in gardens (A). Others consume fungus, such as mildew and plant molds (B). Predatory species may supplement their diet with pollen (C).
Non-prey foods are an integral component of the diets of most predaceous coccinellids. Under field conditions, numerous coccinellids consume nectar, honeydew, pollen, fruit, vegetation
, and fungus
. These non-prey foods are used by coccinellids to increase survival when prey is scarce, reduce mortality during diapause, fuel migration, and enhance reproductive capacity. Each of these non-prey foods has unique nutritional and defensive characteristics that influence its suitability for lady beetles. (15)
Larvae go through 4 different instars before pupating and finally becoming adults. Some larvae have tufts of white wax on the surface that make them look like mealybugs.
Their food is usually similar to that of the adults, and in the predatory species they're often important as pest controls.
Before becoming adults, they go through an immobile stage with a shell-like skin. They shed this pupal case to emerge as adults.
Many species gather in large numbers to hibernate. Some gather along lake shores, particularly in the spring and fall (16)(17)(12)
see BugGuide Eggs, Larvae, and Pupa
info page for more information including current images of species.
Identification within the family (at least for adults) often depends on patterns in the pronotum (the area in front of the wings/"shell", but behind the head). A view of your ladybird from the front will help with ID.

By 1985, more than 100 species of exotic lady beetles had been introduced into California(20)
Some lady beetles, particularly Harmonia axyridis, serve as hosts to parasitic Laboulbeniales fungi, resulting in this appearance (click on thumbs to see comments):
Most other beetles have longer antennae, but some are superficially similar:
(tarsi appear 4-4-4, while in lady beetles appear 3-3-3.
