Answer: Insects
They flew over 300 million years ago.
Q2: How many pairs of wings do most adult insects have?
Answer: Two
Flies are an exception.
Q3: What are a fly's halteres?
Answer: Tiny balancing organs that replaced hindwings
They work like gyroscopes.
Q4: About how fast can some midges beat their wings?
Answer: About 1,000 times a second
This makes a high-pitched whine.
Q5: Which wings do beetles use to fly?
Answer: Hindwings
Elytra lift up to let hindwings work.

The Insect Wings Quiz – The First Flyers

Insects were the first animals to fly, taking to the air over 300 million years ago, long before birds, bats or pterosaurs. Most adult insects have two pairs of wings made of thin cuticle supported by veins.

Insect wings vary greatly. Beetles protect their flying wings under hard elytra, flies use one pair plus balancing halteres and bees hook their wings together. Dragonflies move each wing independently, while midges beat their wings around 1,000 times a second.

Insect flight is so efficient that engineers study it to design tiny drones. Wing patterns and colors also help with camouflage, warning and attracting mates, as seen in butterflies and moths.
