An entomologist is a scientist who studies insects.

Entomologists might spend their days observing how ants build their colonies, discovering why certain beetles glow in the dark, or figuring out how butterflies navigate thousands of miles during migration. Some entomologists work in laboratories, examining insects under microscopes. Others travel to rainforests or deserts to find new species that no one has ever documented before.

This field matters more than you might think. Entomologists help farmers protect crops from destructive insects while preserving helpful ones like bees that pollinate plants. They track disease-carrying mosquitoes and develop ways to control them.

Some entomologists focus on just one type of insect for their whole career. A scientist might become the world's expert on a particular species of moth or beetle. Others study how insects communicate, how they've evolved over millions of years, or how climate change affects their populations. With over a million known insect species (and probably millions more undiscovered), entomologists never run out of mysteries to solve.
