What Are Large Spotted Ladybirds?

Large Spotted Ladybirds, scientifically known as Harmonia conformis, belong to the Coccinellidae family; commonly known as the ladybug family.

The common name of this particular species derives from its large, distinctively spotted pattern on its back and wings.

These small beetles, which measure only a few millimeters in length, can typically be found in temperate regions throughout Australia, although they may occasionally be found in more exotic areas.

What Do Large Spotted Ladybirds Look Like?

The Harmonia conformis is easily identifiable by its distinctive spotted pattern. It usually has 20 black spots, with 18 on its wing covers.

This species can also be identified from other ladybird species by its larger sizes, ranging from 6 to 7 mm in length.

They also have an oval-shaped body with an almost oil-polished sheen.

The head of the Large Spotted Ladybird is black and has two pairs of antennae, with the top pair being longer and thinner than the bottom pair.

The insect also has a pair of telescopic wings that allow it to fly and navigate through the air.

Benefits Of Using Large Spotted Ladybirds

Using Large Spotted Ladybirds in vivariums or gardens can provide a natural way to control pests while adding a vibrant, captivating display to any living space.

Having these beetles in a setup helps to promote health and strengthen the natural ecosystem of the living space.

Their consumption of pests, such as aphids and other small insects, helps to reduce the number of pests present and prevents them from invading the living space itself.

With this natural predation, Harmonia conformis provides a convenient, effective, and beautiful pest-controlling solution for any living environment.

Large Spotted Ladybird Facts

The Large Spotted Ladybird is a species of beetle that typically prefer warm, wooded areas and tend to have a diet of aphids, mites, caterpillars, and various other insects.

They have a lifespan of typically one year and reproduce through a combination of predetermined sex roles and mating rituals.

These beautiful creatures play an important role in the regulation of pest populations that can lead to disruption of local ecosystems.


Harmonia conformis, hailing from Australia, has successfully made its way to New Zealand as well.

They have since spread throughout most of the temperate regions of the world and are generally found in agricultural grasslands, where they have ample food sources.

These lady beetles enjoy sunny, warm meadows and have been spotted in gardens, fields, and crops.

Although they can thrive in a variety of environments, they do not do well in severe weather conditions.

In the wild, Large Spotted Ladybirds inhabit areas with intensive agriculture, as the lack of grass in agricultural areas allows for plenty of sunlight and a plentiful source of food.

The beetles can also be found resting and sheltering in various cracks and crevices.


Harmonia conformis is a predator that primarily feeds on aphids and other small insects, such as mites, insect eggs, and caterpillars.

These ladybirds have a flexible diet; in addition to the small insects they commonly feed on, they have also been known to consume pollen, nectar, and even fungi.

Interestingly, the Large Spotted Ladybird is also a scavenger, particularly when food sources become limited.

As a result, it may feed on carrion or dead insects as well.

Like many other ladybird species, the ladybug uses its long, curved mouthparts to probe their host’s bodies for food and liquefy their prey.

This helps them to extract more nutrient-rich substances that are otherwise inaccessible to them.

Additionally, they have also been observed feeding communally, which is beneficial for the entire colony as nutrients are distributed equally among the members.


Harmonia conformis is a relatively peaceful creature.

They are generally quite timid around humans and do not typically behave aggressively unless they feel threatened.

While these creatures may appear intimidating, with their large spotted wings and colorful hue, they are actually known to be quite docile. 

In the presence of other animals, Large Spotted Ladybirds display a curious nature.

They are typically observed using their antennae to investigate objects in their environment, like plants and small rocks.

They are highly unlikely to interact with larger mammals, like cats and dogs, and chances of the Ladybirds biting or stinging are nonexistent. 

On the other hand, Large Spotted Ladybirds often coexist peacefully with other insects, like flies and the Asian Ladybird.

These beetles have been observed gathering in small groups or ‘feeding mobs’ when food is in abundance.

These gatherings typically last a few minutes to a few hours, and when the food source becomes depleted they will disperse. 


The lifespan of Harmonia conformis generally ranges between nine to twelve months, although some may live longer.

They typically die from dehydration, hunger, and cold temperatures during winter months.

Upon reaching sexual maturity, they mate and reproduce during summertime.

The adult Large Spotted Ladybirds often spend their days hunting or basking in the sun on warm foliage.

Females lay eggs near food sources that will provide sustenance for their larvae once they hatch.

The larvae then feed on a variety of small creatures such as aphids, thrips, mites, and beetles.

They gradually molt and shed their exoskeleton several times before reaching adulthood.

When summer passes, the adults hibernate in clusters on and below large objects such as tree bark and stones to withstand the cold winter months.

When the weather warms, the ladybirds become active and typically return to their original food sources.

They may also disperse and move to new territories in order to find more abundant food resources.


The Large Spotted Ladybirds mate seasonally and the female will lay her eggs on the host of her choice, usually the leaves of plants or trees.

The eggs usually hatch within 7-10 days and the larvae need to feed upon soft-bodied prey such as aphids and mealy bugs until they pupate.

The pupal stage is the last stage of development before the adult ladybird emerges.

The adult Harmonia conformis will emerge in the Spring and they last through to mid-summer when mating season begins again.

During the mating season, the male and female will couple up and mate for long periods of time.

The female averages about 90 eggs over her lifetime, which are deposited in batches of 6-18 at a time. 

The newly hatched larvae will feed upon their prey in order to survive their first few weeks before reaching adulthood and beginning the cycle again.

Where To Find Large Spotted Ladybirds

If you’re looking to find Harmonia conformis in the wild, you are likely to find them in meadows, parks, and gardens.

They are usually found congregated along flowers, bushes, and other foliage where they can catch their food.

They can also be found in regions with mild winters, so avoid colder areas.

Finding Large Spotted Ladybirds for sale can be a bit more challenging.

It is vital to buy from a reliable supplier that takes the necessary steps for the safety and well-being of the species.

The exact origin of the larvae is essential in ensuring that the ladybird is safe and healthy.

Purchasing from a licensed supplier is strongly recommended, as it not only ensures that you get a healthy large spotted Ladybug but also helps support the species.

Large Spotted Ladybird Care

Caring for Harmonia conformis requires understanding their habitat, diets, and behavior.

It is essential to provide them with a sheltered space, away from chemical pesticides and other pollutants.

The ideal tank setup for these beetles is a terrarium that has not been treated with any chemicals and is large enough for them to roam around.

The optimal water pH for this species is slightly basic at 7.0-7.5, and water hardness should stay at a maximum of 10 GH.

The temperature should be between 24-26 degrees Celsius and the terrarium substrate should be organic and moisture-rich such as coco fiber soil and sphagnum moss.

Additionally, terrarium lighting should be a combination of both UVB and UVA to simulate natural daylight.

What Do Large Spotted Ladybirds Eat?

Feeding Harmonia conformis is an important part of any conservation efforts.

Here are a few tips on how to feed these amazing bugs: 

  1. Offer them a variety of food sources, such as pollen, nectar, small insects, and aphids.
  2. Provide a flat surface or substrate (e.g., sand, gravel, etc.) for them to climb onto and feed from easily.
  3. Place the food in shallow dishes, as ladybirds are hesitant to go too deep into the water.
  4. Place the dishes in shady areas away from wind and draft.
  5. Avoid using pesticides, insecticides, fungicides, and other chemical treatments in the environment, as these can poison ladybirds.
