How Long Do Ladybugs Live?


How Long Do Ladybugs Live?

One of the rare insects that humans enjoy having around is the beloved ladybug. You could believe that a ladybug’s number of spots can be used to estimate its age. But how long do ladybugs actually live?

Ladybugs typically live for 1-2 years. Some can live to be two years old because they can survive longer under the appropriate circumstances. They generally require the proper environment, diet, and general health.

It can be pleasant to have ladybugs around. Additionally, they greatly benefit your yard by keeping dangerous bugs out. Understanding the ladybug’s life cycle might help you better grasp how long they live and the elements that influence this.

Everything you need to know about the ladybug’s life cycle is covered in this tutorial.

Let’s get going.

How long do ladybugs live?

It’s a frequent misconception that you can determine a ladybug’s age by counting their spots.

Although it would be a terrific technique to quickly determine how old a ladybug is, it is untrue. The seven-spotted species of ladybug, which is the most prevalent, would have been seven years old. If ladybugs could live this long, it would be amazing, but alas, they can’t.

Small insects known as ladybugs typically live for about a year, but they can live for up to two. Thus, it follows that some people have a double the lifespan of others. The cause of this is that the circumstances individuals encounter during life will affect how long they live. This covers factors including weather, predators, and food availability.

Ladybug life cycle stages

Ladybug life cycle stages

The barriers to a ladybug’s survival can vary depending on where they are in their life cycle. Let’s examine each phase of the ladybug life cycle in detail.


Around 20 eggs are laid by female ladybugs in a clutch on the underside of a leaf or a plant. The ladies go without coming back to guard the eggs once they are placed. This means that as soon as they are laid, the eggs are exposed to predators. The eggs are hidden from view by being laid on the underside of plants.

Larvae are helped to survive by adults by being laid on a good food source. Any larvae have immediate access to food as a result of this.

If there is not enough food available when the eggs hatch, the unhatched eggs may even be in danger of being devoured by their siblings.


Around 3 to 10 days after being placed, ladybug eggs begin to hatch once the temperature is ideal. The larvae emerge as a lengthy bug with a spiky shell from the eggs.

To advance to the next stage of their life cycle, these larvae must develop quickly, which necessitates ingesting a lot of insects. At this point, they begin to attack the host plant’s neighboring aphids.

The adult female or male does not come back to look after the young. Despite becoming far more vulnerable to predators as a result, they are nevertheless able to flee from harm.

Before they are big enough to move on to the next stage, ladybug larvae need to grow and molt for around 3–4 weeks.


The larva will cling to a leaf when it is big enough to enter the pupal stage. They are transforming into their mature form during this phase.

The ladybug remains still in the same location while going through numerous physical changes. Due to their inability to defend themselves, they become once more prey to predators.

It takes the ladybug about 1-2 weeks to complete this stage of its existence.


The adult ladybugs are first fragile after they emerge. This is due to the fact that their delicate shells take some time to solidify. The hue of newly hatched adult ladybugs gradually darkens over time, making this process clear.

Temperature and sunshine availability are key factors in this entire process.

The ladybug is most protected from predators during the adult stage. This is due to their physical protection provided by their shell and ability to fly.

After feeding consistently for a month, adult ladybugs will become inactive for around 6-7 months in the fall and winter.

How do ladybugs die?

Conditions in a ladybug’s life can affect their chance of surviving. Let’s examine what causes a ladybug to perish.

1. Food availablity

Ladybugs are active little insects that require a consistent food source to survive.

Although the majority of a ladybug’s diet consists on insects, they also have access to other energy sources.

The issue with a diet heavy in insects is that as the insects go dormant during the colder months, supplies soon diminish.

Ladybugs must enter a condition of dormancy in order to survive those months.

Food supplies can be scarce even during the warmer months. This means that if their typical insect supply is absent, ladybugs may have to rely on other food sources like nectar or pollen.

Ladybugs have been known to consume their own species’ eggs in order to survive. Immature ladybugs can’t move on to the next stage of their life cycle without a constant source of food. The quantity of ladybugs that mature as a result of this is affected.

2. Predators

As insects, ladybugs are at the bottom of the food chain for bigger creatures. One of the greatest dangers to ladybug survival in the outdoors is predators.

Typical ladybug predators include:

  • Birds
  • Spiders
  • Wasps
  • Frogs
  • Dragonflies
  • Lizards

Predators will typically capture ladybugs when they are still in their egg, larval, or pupal stages. This is due to the fact that they are currently unable to fly. The larvae can move but are immature and unaccustomed to predators, while the eggs and pupae remain stationary.

Adult ladybugs frequently have to flee from circumstances where they risk being eaten, thus they rely on their ability to fly. Additionally, they defend themselves against prospective predators by using their colors. They appear to be poisonous to eat because of their crimson hue and black markings.

In order to prevent becoming sick again, predators may have had a negative experience eating a bug with a similar coloring in the past.

3. Disease and parasites

The length of a ladybug’s life is significantly influenced by their general health. The main danger to their health that might cause illness or death is disease and parasites.

Typical parasites and illnesses that afflict ladybugs include:

  • Laboulbeniales
  • virus that causes paralysis in dinocampus (DcPV)
  • Phalacrotophora
  • Tachinidae
  • Testrastichinae

There are no known diseases that ladybugs can transmit to people.

A ladybug is effectively dead if it contracts a disease or becomes parasitized. This is so because the majority of these are parasites that attack ladybugs and use their hosts’ bodies as their own. This indicates that the ladybug is still alive but under the parasite’s control.

4. Injury

How long do ladybugs live?

Ladybugs are particularly vulnerable to serious harm as insects. An injured ladybug is probably unable to escape predators or get food.

The harm done to ladybugs is largely the result of human intervention. For ladybugs, insecticide use is a major issue. Insecticides will quickly poison ladybugs once they’ve consumed them.

Pesticides are frequently used by gardeners to get rid of aphids on their plants. The deadly chemicals used to eliminate the nuisance insects come into touch with the ladybugs once they arrive to devour the aphids.

The usage of insect traps, such as sticky tapes or glue, is another frequent reason why ladybugs are hurt. These traps are quite easy for ladybugs to be caught in, and they often die while trying to escape. They could starve to death if they are unable to flee.

Insects can harm ladybugs as they attempt to flee a confrontation. If ladybugs get in the way of the ants’ herding of aphids, the ants will attack the ladybugs.

A ladybug with a broken wing is not likely to live very long. This frequently occurs when the ladybug gets older and its body becomes more brittle.

5. Climate

Since ladybugs are insects, they experience a period of diapause during the winter. They can survive the winter’s frigid temperatures and scarcity of food because to this condition of hibernation.

Ladybugs typically don’t die in cold weather; instead, they enter a state of diapause.

But at any time of the year, an unexpected cold snap could make them prey targets. Predators are likely to consume ladybugs during diapause if they aren’t securely hidden.

Another element that affects ladybug survival is humidity. Ladybugs prefer a humid atmosphere, and too dry an environment might cause them to get dehydrated and indicate a lack of food. Ladybugs prefer a climate with about 60% humidity, but they can probably survive in a climate with much lower humidity. Because of this, ladybugs thrive in regions with a moderate climate.

How long do ladybugs live indoors?

Ladybugs are able to enjoy indoor lives as pets. Like in the wild, a ladybug living indoors will have a lifespan of 1-2 years.

This is so because a ladybug can only live to this age naturally. When they dwell indoors, their odds of reaching the age of two are substantially higher.

The ladybugs are better safeguarded when kept as pets. They enjoy frequent access to food as well as defense against parasites and predators.

Final thoughts

Most ladybugs only survive for around one to two years, and the most of them perish in the first year.

A ladybug’s life expectancy will depend on a number of factors. This covers their accessibility to food, exposure to predators, and overall surroundings. They will all have an impact on their survival rates.

Small insects called ladybugs can be severely impacted by animals higher on the food chain. The longevity of ladybugs can also be significantly impacted by human activity.

Despite this, ladybugs are extremely adaptable creatures that can reproduce quickly to protect the species.


How often do ladybugs need to eat?

Plan to just feed your ladybug once or twice every day to avoid overfeeding it. If you wish to take care of a lot of ladybugs at once, bear in mind that they consume a lot for their size, so you’ll need to provide enough food to keep them all content.

What kills ladybugs in the house?

An easy technique to get rid of bugs in your house is to use diatomaceous earth. Typically, you can purchase the white powder online or even at your neighborhood home improvement store. To prevent and get rid of new infestations, sprinkle the powder around your colony or around the edges of common entry holes.

How many babies can ladybugs have at once?

After mating, the female deposits between 10 and 50 eggs on a plant that will provide abundant of food for her young once they hatch, typically a plant that is plagued with aphids, scale, or mealybugs. One female ladybug can produce up to 1,000 eggs between the spring and early summer.

What is the life cycle of a ladybug?

In a process known as metamorphosis, which occurs when an organism totally transforms while progressing through the phases of its life cycle, ladybugs shift through four stages. Egg, larva, pupa, and adult are the different stages of the ladybug life cycle. Each stage of a ladybug has a very distinct appearance. Now let’s investigate them.

How long can ladybugs live without food?

Around 5,000 different species of ladybugs can be found worldwide. They can endure almost any environment and last up to nine months without eating! The convergent ladybug is the most prevalent species of ladybug in North America (Hippodamia convergens).
