Tiny and Mighty Creatures

Insects comprise the largest group of living beings on Earth. They play many different roles in the ecosystem, all of them important both for humans and the environment.

Here we have a small sample of insects from around the world, which are part of the Invertebrate Zoology Collection of the Natural Science Research Laboratory of the Museum of Texas Tech University.

These are some of the key roles that insects play:


Those who transfer pollen across plants to help them produce fruits and seeds.

Insect pollinators: bees, butterflies, and flies

To learn more about pollinators and pollination, go to the website that graduate student Alyssa DeWaele put together about this.


They feed on other insects or other invertebrates. Free pest control.

The recycling team. They help breaking down organic matter, returning nutrients to the soil.

Termites, a hide beetle, and a dung beetle


Plant feeders

A large proportion of insects feed on plants, on different parts of them.

Insects as food

Many animals depend on insects as a food resource with high content of protein and fat.
