Period 6



Green Darner Dragonfly

Anax Junius





Dragonflies actually look like helicopters or you can say helicopters are inspired from the shape of Dragonflies. Green Darner Dragonfly has green color and sometimes combined with other color so it can make some kind of pattern of color. It has four transparent wings. The wings themselves are really smooth, transparent and light so the Green Darner Dragonfly can float in the air by swinging their wings. Green Darner Dragonfly also has huge eyes.



Green Darner Dragonflies are found throughout North and South America, the West Indies and Asia. And there is certain type of Green Darner Dragonfly found in Hawaii that has a green thorax and blue abdomen rides the thermals Waimea Canyon.



Green Darner Dragonfly is usually found and hanging around ponds and slow stream. It also can be found around the rice fields in the South East Asia. Typically found at an altitude of 0 to 5,478 meters.



Green Darner Dragonfly is a predator. They prey other insects or bugs which are smaller than their size. Adults hunt while airborne over sunny fields and meadows, preying on midges, mosquitoes, caddisflies and other flying insects



It keeps the food chain by eating small bugs or insects that can destroy the plants’ leaves or flowers. Also dragonfly eats mosquitoes that can be dangerous and annoying for human.



There are some facts that can be interesting in Green Darner Dragonfly. Green Darner Dragonfly are usually nicknamed darning needles, mosquito hawks, and Lord of June. Enabled by their excellent flight capabilities and nearly 360-degree eyesight, dragonflies easily capture and kill prey larger than themselves. The Green Darner can fly at speeds exceeding 50 miles per hour. Dragonflies are among the most ancient of living creatures. Fossil records, clearly recognizable as the ancestors of our present day odonates, go back to Carboniferous times which means that the insects were flying more than 300 million years ago, predating dinosaurs by over 100 million years and birds by some 150 million. Dragonfly sex involves one very unusual step: before mating, the male must transfer sperm from his sperm-producing genitals (located in segment 9, at the tip of his abdomen) to the accesory genitals located on segments 2 and 3, underneath his abdomen. These include a sperm resrvoir and a penis. Male dragonflies accomplish this transfer solo, before they attempt to copulate. This type of sperm transfer is unique to the Odonates among insects, although it is common in spiders.
