Dragonfly - The champion flies away in the insect world

Scientific journal Plos One asserted that the famous Danaus plexippus butterfly must cede the title of champion to far fly in the insect world for the new champion, the Pantala flavescens dragonfly.

During the annual migrations, Danaus plexippus butterflies cross the road to 8,000km, thinking that they are champions of flying insects in all kinds of insects, but according to the latest figures, the Pantala flavescens dragonflies also move to 14,000-18,000km.

Dragonfly Pantala flavescens.

Pantala flavescens with small appearance, bodies longer than 4cm long have been designated as the most popular dragonfly species in the world. They live in most parts of Africa and Central America, the eastern United States, most of Asia and Australia. They are seen flying on the remote islands of the Pacific Ocean, they are the only dragonflies on Easter Island. There are times when they are in Southern Europe, although dry winds from the Sahara desert interfere with them on the way.

Scientists have hypothesized that Pantala flavescens represent species of uniformly-inhabited dragonfly populations on most of the Earth. A recent genetic study has confirmed that hypothesis. Scientists analyzed dragonfly genomes captured in North America and South America and Asia and found that even those living in remote areas like Texas and India have genomes. Amazingly similar. That means dragonflies have to go a long way to find mate.

In the past, scientists had known the "bloody" of Pantala flavescens when they gathered into densely packed herds in the direction of hot, wet winds to fly away. In many countries in the Indian Ocean, dragonflies appear in the rainy season. According to calculations by scientists, there are dense migratory flying swarms up to 32 km ^{2 wide} . The authors of the study want to track the Pantala flavescens dragon migratory routes, but have yet to find a way by the modern devices used to monitor migratory animals that are too cumbersome for animals. little dragonfly.
