Explanations: answer key for all 10 questions

Q1: What kind of eyes do dragonflies have?
Answer: Huge compound eyes
They cover much of the head.
Q2: About how many tiny units can each eye have?
Answer: Up to around 30,000
Each unit is an ommatidium.
Q3: How wide is a dragonfly's field of view?
Answer: Almost all the way around
Blind spots are small.
Q4: Which light can dragonflies see that humans cannot?
Answer: Ultraviolet
Many insects see UV.
Q5: What else can they detect?
Answer: Polarized light
It helps find water.
Q6: How fast is their visual processing?
Answer: Very fast, catching quick movements
Motion looks slower to them.
Q7: How do dragonflies catch prey?
Answer: By predicting the prey's path and intercepting it
They aim ahead of the target.
Q8: How successful are dragonflies at hunting?
Answer: Among the most successful predators
Some studies show over 90 percent success.
Q9: What do adult dragonflies eat?
Answer: Flying insects like mosquitoes
They catch prey in the air.
Q10: How do they grab prey in flight?
Answer: With their legs, like a basket
Legs form a spiny trap.

Eyes Built for Hunting in the Air

Dragonflies have enormous compound eyes that cover much of the head. Each eye can contain up to around 30,000 tiny units called ommatidia, giving a view almost all the way around the body. Dragonflies can see ultraviolet light, which humans cannot, and detect polarized light, which may help them find water.

Their visual processing is very fast, so quick movements that would blur for us look slower to them. When hunting, a dragonfly predicts where its prey is heading and flies to intercept it rather than simply chasing. Some studies show catch rates of over 90 percent, making dragonflies among the most successful predators in nature.

Adult dragonflies catch flying insects such as mosquitoes and flies, grabbing them with their legs, which form a spiny basket in flight. Scientists study dragonfly vision and brain circuits to design better drones and tracking systems.
