Many eat aphids and other small pests, but diets and winter behavior vary by species—and a few lady beetles feed on plants.
Here are nine facts that help explain what these insects look like, eat, and do through the seasons.
1. Ladybugs are beetles, not true bugs
Despite the name, ladybugs are beetles in the family Coccinellidae, within the order Coleoptera. “Lady beetle” and “ladybird beetle” are more precise common names; true bugs belong to a different insect group.
University of Florida IFAS Extension identifies ladybirds as members of Coleoptera and the family Coccinellidae.

2. Lady beetles come in more colors than red
Lady beetles may be red, orange, yellow, pink, or black. Their colors and patterns vary among species, so the familiar red-and-black appearance is not a reliable description of the whole family.
For local identification, compare the beetle’s markings and other features with a regional guide rather than relying on color alone. The Cornell University Cooperative Extension guide describes lady beetle diversity and feeding habits.
3. Some lady beetles have few or no spots
Spot patterns differ among species, and some lady beetles have few or no spots. Counting spots does not tell you how old an individual beetle is; markings are an aspect of appearance, not a dependable age counter.
4. Their young look like tiny alligators
Lady beetle larvae look very different from the rounded adults. They are elongated and often dark, with bright markings and a spiny appearance that can remind people of miniature alligators.
Rank #2
The larval form is a normal life stage, not a separate kind of beetle. University of Minnesota Extension describes and illustrates the life stages.
5. Lady beetles pass through four life stages
Like other beetles, lady beetles undergo complete metamorphosis. Their life cycle has four stages:
- Egg: The first stage.
- Larva: The elongated, active young stage.
- Pupa: The transformation stage between larva and adult.
- Adult: The familiar beetle form.
The stages look different, especially the larva and adult. Timing varies with species and conditions, so there is no single schedule that applies to every lady beetle.
6. Aphids are only part of the menu
Many adult lady beetles and larvae prey on aphids and other small pests. Depending on the species, their food can also include mites, insect eggs, small insects, pollen, or nectar. Some species eat substantial amounts of pollen.

That variety matters: not every lady beetle eats the same prey, and not every species is a garden pest predator. Cornell University Cooperative Extension describes these differences in diet.
7. A few lady beetle species feed on plants
Most lady beetles are predators, but a few eat plants. Cornell identifies the Mexican bean beetle and squash beetle as plant-feeding exceptions. The common name alone does not tell you whether a beetle is helpful to a particular plant.
If a beetle is damaging a crop or garden, identify the species before deciding how to respond.
8. Some release a smelly defensive fluid
When disturbed, some lady beetles release a foul-smelling, unpleasant fluid from joints in their legs. Their conspicuous colors can also serve as warning coloration to predators.

Not every species has identical defenses. Handle beetles gently and avoid touching your eyes after handling them.

Many lady beetles overwinter as adults in protected places such as leaf litter, rocks, bark, hedgerows, or buildings. Some gather in clusters, and some may enter homes while seeking shelter.
Winter habits vary by species and location. A group of beetles indoors may be looking for a protected place to overwinter; identifying the species can help explain what you are seeing.

FAQ
Are ladybugs really bugs?
They are beetles, not true bugs. “Ladybug” is a familiar common name; “lady beetle” is more precise.
Do all ladybugs have spots?
No. Lady beetle markings vary by species, and some have few or no spots.
What do ladybugs eat?
Many eat aphids and other small prey. Depending on the species, lady beetles may also eat mites, insect eggs, other small insects, pollen, or nectar. A few species feed on plants.
What do baby ladybugs look like?
Young lady beetles are larvae: elongated, often dark, and sometimes brightly marked and spiny. They look quite different from the rounded adults.
Why do ladybugs smell?
Some lady beetles release an unpleasant defensive fluid from their leg joints when disturbed. The fluid and defensive behavior vary among species.
Where do ladybugs go in winter?
Many overwinter as adults in protected sites, including leaf litter, rocks, bark, hedgerows, or buildings. Some gather in groups, and some enter homes seeking shelter.
