Meet the Tau Emerald Dragonfly
The tau emerald is a medium-sized dragonfly. It has a body length of about 50 mm, which is about the length of your thumb! These dragonflies are mostly black and yellow. They also have long legs, which help them catch other insects while flying.
What Makes It Special?
One special thing about the tau emerald is its wings. Both male and female tau emeralds have hindwings with a rounded inner edge. This unique shape helps scientists tell them apart from other dragonflies.
Where Do Tau Emeralds Live?
You can find the tau emerald dragonfly almost everywhere in Australia. They live in most parts of the country. However, you won't usually see them in northern Queensland or the very north-western part of Western Australia. They prefer areas with water, like ponds, lakes, and slow-moving rivers.
Who Discovered the Tau Emerald?
The tau emerald was first officially described in 1871. A scientist named Edmond de Sélys Longchamps was the one who gave it its scientific name. He was a very important expert on dragonflies and damselflies.
