Pollinators like this bumblebee are essential for reproduction in 80% of all plants and 90% of all flowering plants. Without pollinators, most of our plants would disappear and so would the food that supports mammals, amphibians, reptiles and birds which are all kinds of animals.
Most birds need thousands of insects to raise their chicks. For example, Chickadees need 6,000-9,000 caterpillars to raise one clutch of chickadees.
If insects go extinct, so will the chickadees.
Insects feed on plants (phytophagous), decomposing materials (saprophagous), other animals (predators and parasites). Assassin bugs and other insect predators provide effective pest control. While, crickets and many other insects quickly decompose dead plants and animals.
The Earth would rot without insects.
Insects can be found everywhere.
There is no stone too small and no mountain too big for insects to flourish.
Insects constitute the largest group, more than 80%, of all animal species and exhibit great diversity with almost 1 million described species.
Insects come in all shades of color and size. No two types are similar and the same insect can change in shape, color and size if it is raised in different environment.
Insects came long before humans and can easily co-exist. They can live in wide range of temperatures ranging from -50 degree Celsius to 40 degree Celsius.
All they need is a chance.
