There are about 375,000 species of beetles, which makes it the most diverse insect in the world. Many of them are considered pests and they cause large crop losses. For example, the pine weevil or bark beetle is considered the most destructive forest pest for pine forests in Mexico and Central America.

But other species have a positive impact. For example, the ladybug feeds on aphids and helps control this insect that attacks crops. The coprophages also play a fundamental role: they are the largest manure recyclers and they also bury them, which fertilizes the soil. Without this action, the accumulation and smell would be unbearable for the ecosystem.
