Jacks of all trades

They play an indispensable role in maintaining the balance of Nature. They improve our quality of life. Sometimes they are actually essential to our survival. Who are they? Insects, of course! They spend their lives working hard to keep our ecosystems running. Thanks to their many skills, they also make a major contribution to the economy. And with their great diversity of shapes and colours, they are a constant source of inspiration and fascination.


SERVING THE ENVIRONMENT

Because they are the primary source of food for many species of fish, amphibians, birds and mammals, insects are essential to these species’ survival. They also play a fundamental role in forming soil and keeping it fertile. They improve the underground environment for roots and help plants grow. Without scavenger insects, the trash, carcasses and fecal matter lying everywhere would be a perfect breeding ground for bacteria. In addition, insects are sensitive to environmental disturbances from pollution or natural phenomena like freezing, drought or ecological catastrophes. For this reason, some species are used as biological indicators.

 

SERVING THE ECONOMY

Insects play a big part in the world economy, by producing honey, wax, silk and dyes. Some 80% of the plants that produce fruit, vegetables, textile fibres, pharmaceutical products, etc. are fertilized by pollinating insects. Others help to control the populations of different pests. They are valuable biological weapons for protecting crops, forests and livestock.

 

SERVING CULTURE

In addition to inspiring artists with their beauty, insects intrigue the scientists who study them and endeavour to understand their structures, physiological adaptations and sometimes unusual behaviour. For collectors, of course, they are often a true passion.


 ROLE PLAYING

All the world’s a stage... and insects play a great variety of parts on it. Can you guess some of their roles? Just circle the correct answers below.

Role playing
  • Ask participants to form small groups, and hand out the activity sheet.
  • Suggest that they discuss the questions and answers in their groups.
  • Then come back together as a large group to compare and talk about their answers.

 

 

  • Conduct a role-playing exercise. Assign one or more scenes to each group. Ask participants to illustrate a certain specific role played by insects for the rest of the group. They may mime or act out the scene, with the help of signs, posters and drawings. A quiz or an improvisational game are other possibilities.
