The most famous clusters of insects
hordes swarm cluster, cloud, horde, legion, and many more adjectives you can think of for this natural phenomenon. Overall - a nightmare and horror.
Swarms of locusts.
One of the most famous clusters of insects - it swarms of locusts, which are called the eighth plagues of Egypt. This is a terrible catastrophe - because locusts devouring everything in its path.
The Record fixed "pack" is amazing - covering an area of locusts was 510,000 square kilometers in the pack, according to rough estimates, there were more than 12 trillion insects, weighing about 27 million tons. It happened in 1875 in North America.
Swarms of ladybirds are often attacked by different areas of the planet.
It happened in Colorado. In 1952, on the coast of a flock has been seen in England, which is in flight stretches almost 65 km.
Butterflies arrange a massive "flight" - migrate. For example, while known beautiful sight migratory chilling Monarch butterflies.
However, and other butterflies can gather in such flocks. Aporia Crataegi example, cabbage, painted lady (Vanessa cardui) and others.
By the way the invasion of the intermediate state between chrysalis and butterfly - caterpillar, too, are quite impressive and have disastrous consequences.
The Asian giant hornet.
The Asian giant hornet can also get off in huge flocks. So, in the Chinese province of Shaanxi in 2013 by a hornet stings, huddled in packs, killing more than 200 people, five hundred more were hospitalized. Bite giant Hymenoptera contains strong neurotoxic poison that destroys the human body tissue, causing this incredible pain.
The African bees.
The African bees - one of the most aggressive among insects. Collision with such hordes of killer bees is very common, for example, in North America each year about 40 people die from the bites of these insects swarms of killer. One example, when a farmer accidentally drove a tractor to an abandoned chicken coop, where there was a swarm of bees and was killed almost in place.
The main difference between African bees in an attack that the air in the event of danger, rises more than defenders and all of them anyway, that they die after being bitten. Mosquitoes.
Yet another killer - mosquitoes slipping into a giant pile - billions
In Texas in 1980, there was a case when more than 20 years, billions of mosquito eggs lay dormant and awake, and soon turned into billions of mosquitoes by flooding the region and attacked the nearest cattle farm.
The migration of ants.
Ants species Dorylus can even cross the wide and fast river to swim across them they were going to balls.
Ants create a very real living walls on trees and shrubs. One need only someone to disturb the "fence" is immediately followed by a furious attack.
The invasion of spiders occur in many areas of our planet. For example, in Australia, Africa, the UK, where these hordes cobwebs cover large areas.
