Have you are wondered why soldiers are always clad in green? This is to enable them to camouflage themselves during wartime. Hiding in the jungles, their green attire blends into the surrounding trees and shrubs, making it difficult for the enemies to spot them.
Long before man-made use of camouflaging, insects have already adopted the tactic of disguise to escape from the clutches of their predators. By having body colour close to those of the rocks and dried leaves, they can escape from being pursued by the predators.
Butterflies and moths have developed a variety of camouflage strategies since they are quite defenceless and their predators are abundant. Possessing wings which resemble dried leaves help certain butterflies and moths to hide among heaps of dried leaves when predators are around.
Fortunately, not all insects choose the art of disguise to escape from their predators; otherwise, the world would be so dull and colourless. There are insects which assimilate the bright body colours of bees and wasps to escape from being pursued by their predator. Long ago, birds have already learnt to avoid brilliantly coloured wasps and bees in fear of their painful stings. Hence, over millions of years, many harmless insects have assimilated the bees and wasps by imitating. their bright body colours and shapes. In this way, they appear dangerous and hence ward them off.
The beefy, not only appears like the bumblebee in terms of body colour, even its hums sound similar too. The only difference is that the beefy does not have a stirring and is hence harmless. The hoverfly is another insect which imitates. the body colours of the wasps. Their bodies are striped yellow and black. The only deviations are that hoverflies do not have stings, and they have only one pair of wings each while wasps have two pairs each. These variations are hardly noticed by the predators and hence help them to escape.
