10 Benefits of Ladybirds (Coccinellidae) and How to Attract Them

Known in the Northern States as ladybugs, ladybirds are not true bugs. Scientists list them as beetles, so their proper names are lady beetles and ladybird beetles.

These lovelies are found in the largest phylum (Arthropoda), class (Insecta), and order (Coleoptera), of which 6000 species spread out across 350 genera in the Coccinellidae family.

Other common names include coccinelle, lady cow, mariquita, gold-cow, cow lady, and gold-hen.


Ladybirds lifespan average 1- 2 years.

If available, fertile eggs are laid in the colonies of aphids and scale insects and infertile eggs if not. This is to ensure the larvae have plenty of food when they first hatch.

The larvae molt about 4 times in a span of 10 to 14 days, and then, they pupate.

They emerge as adults in a couple of days and are ready to mate not long after.


Lady beetles range in color and size, with some mistaken for other types of beetles.

They mostly have red, orange, or yellow bodies with black spots, but they can also range in color from solid black to brown.

Besides, they can possess spots, stripes, or just be plain. They are tiny (between .03 to .7 inches) and round in shape with black on their heads, legs, and antennae.

Larvae and adults have three natural defense mechanisms to keep predators from eating them.

  • One is their shape. They’re round, and the predators have a hard time getting leverage to pick them up. If it doesn’t help, the beetles flatten themselves against whatever they are holding on to as well.
  • The second is its color. Helpful predators such as birds have learned certain colors mean a bad taste.
  • The last is the toxin they release when they’re grabbed. It’s an alkaloid and makes them taste bad, so predators tend to drop or spit them out.

Ladybird Garden Benefits

Most are quite beneficial to people, whether they are farmers, gardeners, or just the ordinary. The following are a few of them.

They are the first line of defense for anyone interested in eco-friendly ways to rid their garden, field, or orchard of pests with their voracious appetites for hundreds of different species of pests.

1. Keep Away Aphids

Aphids are the prime source of food for most Coccinellidae species.

A single ladybird insect, from larvae to adults will consume about 5000 aphids before it dies.

Should not be introduced before you see aphids because they won’t stay. There won’t be anything for them to eat.

2. Pollinators

Ladybugs are great little pollinators. They like to eat some pollen and nectar.

While roving among flowers, pollen tends to stick to them as they move about, which then fertilizes the flowers.

3. Kill Spider Mites  

The smell of the mites, along with the damage they do feeding in herds help the lady beetles find them.

They then walk up to it and start eating. Just one lady bird can eat up to 100 spider mites a day.

4. Mealybugs

Cryptolaemus montrouzieri aka Crypt or Mealybug Destroyer are the names the species that specializes in eating mealybugs are known by.

The adult female lays her eggs in the masses made by mealybugs, and the larvae eat everything they can find.

5. Borer Control

In a single day, a ladybug can eat up to 60 eggs. They leave the eating of the larvae and adults to other predator insects.

6. Colorado Potato Beetle

They eat these potato beetle eggs wherever they find them, so they’re great at preventing an infestation before it begins.

7. Beautify the Garden

The lady beetle’s appearance, with its vibrant colors and gorgeous wings, brings additional beauty to any garden it’s living in.

8. Whitefly Control

Delphastus is the specie that specializes in eating whiteflies.

60 eggs a day is a lot for one little bug, but it does it. It also walks up to adults and just eats them.

9. Lace Bugs

They eat all stages of the lace bug from egg to adult thus controlling all aspects of an infestation.

10. Thrips

This is another insect they are effective at controlling as they eat all stages of the thrips’ life cycle — from egg to adult.

How to Attract Ladybirds to Your Garden

You can buy ladybugs  for your gardens, but the consensus is that attracting them is far better.

Buying them doesn’t guarantee they will feed because of the stress of moving.

Attracting them ensures they will dig into the feast you’re providing them. Here are a few ways:

Plant Nectar and Pollen Plants

Plant a few flowers and herbs that have white and yellow blooms and flat leaves. The flat leaves give them a place to land and the flowers provide pollen and nectar.

Some of these include marigold, angelica, calendula, yarrow, chives, feverfew, and dill.

Provide Plenty to Eat

If you don’t have enough pest insects already in the garden, you can plant some trap plants to draw in aphids — their favorite food.

Traps plants include marigold, radish, kale, sweet cabbage, roses, arugula, and nasturtium.

Quench Their Thirst

Place bowls of water with pebbles inside in and around your garden. The stones give them a place to safely rest while they drink.

Don’t Use Chemical Pesticides

Natural pesticides should be used with caution as well. Chemical pesticides will kill lady beetles outright.

Depending upon what it is, some natural ones will, at worst, kill them and best, drive them away from your garden, so be careful.


Whether you know them as ladybirds or ladybugs, these cute little beetles are not only the most helpful you can have in your garden, they are amongst the more colorful.

Appearing in early Spring, they herald in the season as it begins to warm, leaving their hiding places in buildings and the like to begin mating, laying eggs, and, of course, eating.
