The antlion is the larval stage of a kind of flying insect. Antlions get their name because they eat mostly ants. They live in dry, sandy areas and make their cocoons out of sand stuck together with silk. The catch ants to eat by digging small pits in the sand. Ants fall into the pits and have trouble getting back out, and the antlion comes out from hiding at the centre of the pit and eats them.

Aphids are a tiny, sapsucking insect. They are attracted to fresh new shoots of plants, especially developing fruit and flowerbuds. They can do a lot of damage to crops, and gardeners do not like them. Aphids can be killed by poison, removed by squirting them off with water from a hose, or their numbers can be reduced naturally by encouraging aphid-eaters like ladybugs and wasps into your garden.

The aphids in the picture are on a the developing flower bud of a rose.

Butterflies are a kind of insect that changes completely as it goes through its life. A butterfly starts as an egg, which hatches into a caterpillar. Caterpillars spend all of their time eating leaves from their favourite plants.

When they are old enough, caterpillars spin a cocoon and while they are asleep inside it, they change into a butterfly. Butterflies eat nectar from flowers, and live for a much, much shorter time than caterpillars.

Cicadas are big, noisy insects that can be found all over the world. Most species are about 2-5cm long but some grow to 16cm long. Only male cicadas make the noise, and they are partly hollow to make the noise louder. Female cicadas are not hollow, and as they are very big and meaty, some people eat them.

Cicadas spend the first part of their life underground as nymphs, a time of their life which can last for up to 17 years. When the nymphs come to the surface, they shed their skin and emerge as winged adult cicadas.
