Plecoptera: stoneflies
Stoneflies are soft-bodied insects that can grow up to 50 millimetres long with a wingspan of 100 millimetres. Adult stoneflies are always found near freshwater as they have aquatic larvae and as adults they are not powerful fliers. |

Senses
There are certain insects that can smell with their antennae, taste with their feet and hear with special organs in their abdomen, front legs or antennae. |

Trichoptera: caddisflies
Caddisflies are related to Lepidoptera and resemble small hairy moths, but their wings are covered in dense hairs rather than scales and they lack the typical curled proboscis of most moths and butterflies. |

What are insects?
Scientists who classify organisms into groups are called taxonomists. They give each living organism a unique scientific name which consists of two parts: genus name and species name. |

Wings: lost and found
To develop wings is an important evolutionary decision for an insect. Wings are part of central adaptation mechanisms allowing insects to escape predators, exploit scattered resources, and disperse into new niches - resulting in radiations into vast numbers of species. |
