1. Natural Pest Controllers

Ladybirds are natural predators of aphids, mites, and other crop-damaging pests. A single ladybird can eat up to **5,000 aphids** in its lifetime!

2. Not All Ladybirds Are Red

Although the classic image is a red beetle with black spots, ladybirds come in many colours, including yellow, orange, white, and black. Their colouration warns predators that they might be toxic.

3. Ladybirds Play Dead

When threatened, ladybirds can pretend to be dead (a behaviour called thanatosis) and also secrete a yellow, foul-smelling liquid from their joints to deter predators.

4. Winter Hibernators

In cooler climates, ladybirds hibernate during winter, often gathering in large groups in protected areas like logs, under rocks, or even in people’s homes.

5. Many Species Worldwide

There are over 5,000 species of ladybirds globally. In Australia, native species such as the Transverse Ladybird (with distinctive red stripes) co-exist with introduced species like the Harlequin Ladybird.

6. Beneficial to Gardeners and Farmers

Farmers and gardeners often introduce ladybirds as a form of natural pest control to reduce the use of chemical pesticides.

7. Short Lifespan

A ladybird’s lifespan typically ranges from 1 to 2 years. They go through a complete metamorphosis with four stages: egg, larva, pupa, and adult.

8. Mating and Egg Laying

Female ladybirds lay their eggs near aphid colonies so that the larvae have an immediate food source upon hatching. They can lay up to 1,000 eggs during their lifetime.

9. Some Ladybirds Are Can be a Nuisance

While most ladybirds are beneficial, some species (like the Harlequin Ladybird) are invasive and can outcompete native ladybirds, posing an ecological threat.

10. Cultural Significance

In many cultures, ladybirds are seen as symbols of good luck and protection. Some folklore suggests that spotting a ladybird brings good fortune. As a child I remember feeling so blessed when a Ladybird would land on me.

Ladybirds are more than just charming beetles – they play a vital role in pest control, come in a variety of colours, and have some surprising behaviours.
