[For Seniors] Insect Trivia Quiz & Fun Facts (1–10)

Mosquitoes also suck things other than human blood. What are they?

When you think of mosquitoes, the first thing that comes to mind is probably “sucking blood.” But in fact, they drink more than just blood.

So what else do they drink? Here’s a hint: something sweet.

The answer is… flower nectar.

Mosquitoes actually sip nectar regularly to replenish their energy.

Only females drink blood, and only because they need it to develop their eggs—males drink nectar exclusively.

Learning a new side of a familiar creature can spark conversation and stimulate the brain while enjoying the feel of the season.

It’s a tidbit you’ll remember the next time you hear that buzzing sound in the summer.

When cicadas are chirping in the background during a phone call, how does it sound to the person on the other end?

How would the sound of cicadas in the background come across to the person on the other end of a phone call? The hint is “how phones work.” Traditional telephones are designed to transmit only the frequency range of the human voice, so higher-pitched sounds like cicadas are cut out.

In other words, the answer is: “You can’t hear them.” The unexpected answer is sure to prompt a “Wow!” and liven up the conversation.

That said, with modern smartphones, the microphone’s performance and the calling app can sometimes let cicada sounds come through.

If this summery sound becomes a topic, it might make people recall their childhood days spent running around or scenes from the countryside.

It’s a warm little quiz that can whisk your heart back to summer with just the chirp of a cicada.

Which of these is not an insect?

firefly
Spider
fly

See the answer

Spider

The correct answer is spiders. Spiders may look similar to insects, but they are not actually insects. Insects have bodies divided into three parts—head, thorax, and abdomen—and they have six legs. In contrast, spiders have two body segments—the cephalothorax and abdomen—and they have eight legs. Spiders are classified as arachnids within the arthropods, making them a different group from insects.

How do water striders move to other bodies of water?

fly away
Walk across/on land
Clinging to a bird and going

See the answer

fly away

Water striders are known for gliding smoothly across the surface of water, but they can actually fly as well. When their habitat dries up or food becomes scarce, they use their wings to move to another body of water. Since we usually only see them on the water’s surface, many people don’t realize they can fly—but in fact, they’re quite active insects.

two weeks

4 months

The life span of the bell cricket is surprisingly short—about four months. They begin to chirp with a beautiful “rinnn-rinnn” sound toward the end of summer, but their life cycle starts when they hatch from eggs in spring, become adults, are active through autumn, and eventually reach the end of their lives.
