🛡️ What Are Chemical Defenses?
Many insects produce or sequester toxic chemicals to defend themselves from predators.
🐞 Examples of Chemical Defenses
- Ladybugs (Coccinellidae): Secrete alkaloids that taste bitter to predators.
- Bombardier beetles: Spray a hot, toxic chemical mixture from their abdomen.
- Monarch butterflies: Store toxins from milkweed plants they eat as caterpillars.
⚗️ How Chemicals Protect Insects
These chemicals can be distasteful, irritating, or even lethal, deterring predators and increasing survival chances.
🌱 Implications for Humans
Studying insect chemical defenses can inspire new natural pesticides or medicines.
