Quick answer
Ladybugs, also called ladybirds, are small round beetles best known for their bright red wing cases and black spots. They are valued by gardeners and farmers because both adults and larvae eat large numbers of aphids and other plant pests. Most ladybugs live about one year.

Biology
Ladybug (Coccinella septempunctata) is classified as Insect with conservation status Least Concern. Typical weight about 0.00002 kg; lifespan around About 1 year.
Ecology
Diet: Carnivore (mostly aphids). Habitat: Gardens, grasslands, woodlands, farmland. Movement and social systems reflect those pressures.
People and this species
Learn before you travel or keep related pets. Wild individuals are not toys; captive care needs species-specific husbandry.

Appearance and warning colors
Ladybugs are small, dome-shaped beetles with hard wing cases that are most often red or orange with black spots, though some species are yellow or black. The bright colors are a warning to predators that the beetle tastes unpleasant. When threatened, a ladybug can release a foul-smelling fluid from its leg joints.
Diet and pest control
Most ladybugs are predators that feed mainly on aphids and other soft-bodied plant pests. A single ladybug can eat thousands of aphids over its life, and the larvae are even hungrier hunters. This appetite makes ladybugs popular natural pest control in gardens and on farms.
Life cycle
Ladybugs go through complete metamorphosis, passing from egg to larva to pupa to adult. The larvae look long and spiky, quite unlike the rounded adults, and spend their time crawling over plants hunting prey. The whole cycle can take just a few weeks in warm weather.
Habitat and range
Ladybugs are found on every continent except Antarctica, living wherever plants and insect prey are common. Many species cluster together in large groups to spend the winter under bark, leaf litter, or inside buildings, emerging again in spring.
Research notes
Figures for ladybugs (Coccinella septempunctata) come from field studies, museum records, and conservation assessments that do not always agree on exact averages. Prefer ranges over single-point claims, and check whether a source describes wild, captive, or mixed populations.
Practical takeaways
If you encounter ladybugs in the wild, prioritise distance and local guidance. If you care for related domestic or captive animals, match diet and housing to species needs rather than generic pet advice. Share accurate status information (Least Concern) when discussing conservation.
