Taxonomy & Classification
Cicadas are fascinating insects known for their loud calls and unique life cycles, with some species emerging only every 17 years. Let's understand the evolutionary journey and classification of these remarkable herbivores.
Lifecycle and Growth
Egg, Nymph, Adult
Egg
Female cicadas deposit hundreds of eggs into plant stems, where they remain until hatching, marking the start of their life cycle.
Nymph
Nymphs live underground, subsisting on root fluids, and undergo several molts before emerging above ground for adulthood.
Adult
Adults emerge synchronously, mate, and create a loud chorus to attract mates, completing their life cycle.
Dietary Habits
A specialized sap feeder, this insect relies on its piercing mouthparts to extract fluids from plant xylem and phloem.
| DIET TYPE | DESCRIPTION |
|---|---|
| Primary Diet | Consumes primarily tree sap from deciduous trees, tapping into various species like oak, maple, and willow. |
| Secondary Diet | Additionally feeds on herbaceous plant fluids when tree sap is less accessible, utilizing nearby vegetation. |
| Occasional | Occasionally exploits agricultural crops or garden plants, especially in areas of dense vegetation or human habitation. |
Behaviour and Adaptations
Discover the fascinating adaptations that enable the Cicada to thrive in its environment.
Sound Amplification
Produces loud, distinctive calls to attract mates and deter predators.

Cicadas improve soil quality by burrowing, enhancing oxygen flow and nutrient distribution.
Nutrient Cyclers
Their decaying bodies enrich the soil with essential nutrients, supporting plant life.
Prey for Predators
Serve as a significant food source for birds, mammals, and other insects.
Conservation Challenges
Understanding and addressing the major threats to Cicada populations.
Habitat Loss
Urbanization and deforestation reduce essential breeding areas for cicadas.
Chemical Exposure
Pesticides and pollutants harm cicada populations and ecosystems.
Climate Change
Altered weather patterns disrupt cicada life cycles and habitats.
Frequently Asked Questions
How long do Cicada live?
Cicadas have varied life spans. Periodical cicadas live underground for 13 to 17 years as nymphs, emerging for a few weeks as adults. Annual cicadas have a shorter lifecycle, spending 2-5 years underground and living as adults for approximately 4-6 weeks.
What do Cicada eat?
Cicadas primarily feed on plant sap, which they obtain by piercing plant stems with their mouthparts. Nymphs feed on root sap underground, while adults consume sap from trees and shrubs. They do not cause significant damage to plants.
Are Cicada poisonous?
Cicadas are not poisonous to humans or animals. They are harmless and do not pose any known toxic threat. However, their loud mating calls can be a nuisance in areas with large populations.
Are Cicada endangered?
Most cicada species are not endangered. While some specific species may face threats due to habitat loss, the majority of cicadas have stable populations. Periodical cicadas, with their massive emergences, are particularly abundant.
What do Cicada symbolize?
In various cultures, cicadas symbolize rebirth, immortality, and transformation due to their unique life cycle. In ancient Chinese and Greek cultures, they were seen as symbols of renewal and resurrection.
Do Cicada bite?
Cicadas do not bite or sting humans. They have mouthparts designed for piercing plant stems to drink sap, not for biting. They are harmless and pose no threat to people or pets.
What color are Cicada?
Cicadas come in various colors, typically featuring earthy tones like green, brown, and black. Some species have vibrant red or orange eyes, adding to their distinctive appearance. Their coloration helps them blend into their surroundings.
Does a Cicada have wings?
Yes, cicadas have wings. Adult cicadas possess two pairs of transparent wings with distinct veins. These wings are used for flying and producing their characteristic loud mating calls by rapidly vibrating them.
What does a Cicada look like?
Cicadas are robust insects with stout bodies, large compound eyes, and membranous wings. They vary in size, typically measuring 1 to 2 inches long. Their prominent eyes and unique wing structure make them easily recognizable.
Is a Cicada an insect?
Yes, a cicada is an insect. It belongs to the order Hemiptera, which includes true bugs. They are known for their piercing-sucking mouthparts and are related to aphids, leafhoppers, and other similar insects.
