1. Are insects beneficial or harmful?
Both. Insects play a vital role in ecosystem services such as pollination and decomposition, but some can also transmit diseases or damage crops.
2. Why are insects declining?
Habitat loss, climate change, and pesticide use are major threats to insect populations.
3. What can I do to help insects?
Reduce pesticide use, plant native species, and support conservation efforts.
4. Are all insects social?
No. Some insects, like ants and bees, are social, while others, like butterflies and beetles, are solitary.
5. What is the largest insect?
The largest insect is the giant weta, a wingless cricket native to New Zealand.
6. What is the smallest insect?
The smallest insect is the parasitic wasp Dicopomorpha echmepterygis, which is only about 0.1 millimeters long.
7. Do insects feel pain?
No. Insects do not have the same nervous system as humans, so they do not experience pain in the same way.
8. How many legs do insects have?
All insects have six legs.
Les Drôles de Petites Bêtes: A Comprehensive Guide to the Fascinating World of Insects
