Damselflies are relatives are dragonflies only smaller with hindwings the same size as the forewings, unlike in dragonflies. The eggs are laid in water where the larvae will hatch a few weeks or months later, depending on the species. The aquatic larval stage can last 1 to 3 years whereby they moult between 5 and 15 times to allow them to grow. They are predators of other insects with a jaw that scoops up prey and makes up the majority of the head. The larvae have 3 pairs of jointed legs for walking, slender abdomens, big eyes, visible wing buds on their thorax and 3 gills on the end of their abdomen which appear as leaf shaped tails. The different species damselfly are widespread across the UK in most freshwater environments such as lakes, ponds, streams and rivers.
