Mayflies have the shortest lives. As nymphs, they spend two to three years at the bottom of lakes and streams. When they emerge on dry land as adults, they live for an average of one or two days.
Locusts are the most destructive insects. The desert locust is the most damaging of them all. Although they are only 4.5-6 cm long, they can eat their body weight in food every day. One tonne of locusts, a fraction of a swarm, can eat the same amount of food in one day as around 2500 people.
The calling song of the African cicada measures at 106.7 decibels (as loud as a road drill),making it the loudest insect. The male cicada produces loud buzzing sounds by vibrating drumlike membranes on its abdomen.
Female Malaysian stick insects lay eggs measuring 1.3 cm —larger than a peanut! Insects, such as cockroaches, lay egg cases that are larger than this, but they contain about 200 individual eggs.
The highest insect jump measured was 70 cm by the froghopper. When it jumps, the froghopper accelerates at 4000 m/ sec and overcomes a G—force of more than 414 times its own body weight.
The world’s largest known spider is a male Goliath bird—eating spider, collected by members of the Pablo San Martin Expedition _ at Rio Cavro, Venezuela in April 1965. It had a legspan of 28 cm —as big as a dinner plate!
With a wingspan of 30 cm, the atlas moth is the biggest recorded moth. It can often be mistaken for a bird.
The Mother-of-Pearl moth caterpillar can travel at 40 cm/ sec, 7 the equivalent of 1.6 km/h. It is the only creature that deliberately rolls away when attacked.
The larva of the North American Polyphemus moth eats anamount equal to 86,000 times its own birthweight in the first 56 days of its life. For a human, this would mean an average baby eating 273 tonnes of food.
Measuring up to 45 cm, the large ‘human’ roundworm infects about one billion people worldwide. Humans can be infected with 3S many as 20 worms. A female worm produces about 300,000 Eggs each day and about eight million in its lifetime.
