Beetle Species

Beetles are everywhere, and there are a whopping 400,000 different species worldwide! Just in the UK 🇬🇧, there are over 4,000 different species and over 30,000 unique beetles species in the USA 🇺🇸 !!.

You’ll find them chilling on flowers, scaling trees, or just strolling along pathways. And there’s no missing some of them – from the shiny green rose chafer to the striking blue stag beetle.

What is a Beetle?

Beetles are insects that form the order Coleoptera. 

There are 30 different types of beetle, with over 400,000 species within those types.

A beetle is a type of insect known for its hard wing covers called “elytra”. These covers protect their delicate wings underneath. Beetles have six legs and antennae that they use to sense their surroundings.

They come in all sorts of sizes, from tiny ones you can barely see to big ones the size of your thumb. Beetles can be found in various colors and patterns, and they live in almost every place on Earth, from deserts to forests to your own backyard!

They play important roles in nature, like breaking down dead things or pollinating flowers.

What is the Lifespan of a Beetle?

Once a beetle has reached adulthood and depending on what species they are, their lifespan will be will be anywhere between 10 days and 6 months.

The lifecycle of a beetle is fascinating and generally consists of four main stages:

  1. Egg: The journey starts when the female beetle lays tiny eggs. Depending on the species, these eggs can be laid in the soil, on plants, or inside other materials.
  2. Larva (Larvae for plural): Once the eggs hatch, out come the larvae, which are often worm-like and might look quite different from the adult beetles. This is the primary feeding stage. These little critters can be quite hungry, munching away to gather energy for the transformations ahead.
  3. Pupa (Pupae for plural): After the larval stage, the beetle enters the pupal stage. During this time, it seems like the beetle is taking a break, but there’s a lot happening inside! The beetle is undergoing a significant transformation. It’s in a protective casing and is reshaping and reorganizing itself to emerge as an adult.
  4. Adult: Out comes the fully formed adult beetle, ready to start the cycle all over again. The adult beetles will mate, and the females will lay more eggs, ensuring the next generation of beetles.

Take a look below and observe just a few of the many species of beetles that inhabit our planet. Click on a beetle below to find out more information.

Atlas Beetle

The Atlas beetle (Chalcosoma atlas) belongs to the family ‘Scarabaeidae’. The Atlas beetle is found in southern Asia, particularly Malaysia.

Weevil Beetle

Due to the shape of their heads, weevils are commonly known as ‘snout beetles’. The adult weevils have a snout and are about one-fourth inch long.

Did You Know?

Beetles aren't just ANY insects; they're the reigning champions! They make up a staggering 40% of all insects we've described and, hold onto your hats, a whopping 25% of ALL animal species on Earth! Now, isn't that simply incredible?!" 🌍🐞🌟
