Types of Insects


A ladybird (or ladybug) can reach top speeds of 24 km an hour and live for around one year. There are approximately 5000 different species of ladybug on earth.

They come in various colors and patterns, and most of us are familiar with this seven-spot ladybird. Most people seem to like them because they are very harmless to humans and beautiful to the eye.

They are also a welcome sight for farmers because they eat aphids, which are plant-eating pests. It’s estimated over a ladybird’s lifetime that they will eat 5000 of these plant-eaters.


Bees are one of the most beneficial insects.

The bumblebee helps pollinate plants and flowers that grow our food.

The honey bee has to fly around 43,000 miles to collect enough nectar to create 1 lb. of honey.

Many types of flying insects have developed coloration patterns that look like ‘eyes’ on their wings.

This is to help avoid a body attack and instead allow a predator to go for the wings.

Corn Rootworm

Insects have many different methods to help them survive the long cold winter.

Crop pests  – are one type of insect that migrates in the US; for example, many will migrate from the north to the south until the spring.

Larvae – many insects will get through the winter as immature larvae. They will hide and shelter in amongst the vegetation. Others can bury themselves deep into the soil to escape the cold.

Nymphs – you do not see a lot of insects during the winter. However, the larvae of mayflies, dragonflies, and stoneflies live in waters often beneath the ice

Eggs – some insects like the Corn Rootworm lay eggs that can survive the winter.

Pupas – Some insects get through the winter in the pupal stage, then emerge as adults in the spring. For example, Moths can survive by attaching to food plant branches.

Hibernation as Adults – insects hibernate as adults. Bees can hide in the eaves and attics of houses or barns. Some butterflies hibernate in tree holes or other similar shelters during the winter.

Overall insects will adapt to survive cold temperatures
