Lightning bugs can blink themselves because of a chemical substance
Lightning bugs are one special species in nature, they have own feature in the abdomen of their bodies, in which there is a chemical substance. And they can light them up and control when they blink and how long they blink.(12)But why lightning bugs light up? The following reasons may account for this. They are basically to find a mate. It’s a way that lightning bugs communicate with each other. They use their blinking signals to attract each other.(13)The female lightning bugs have brighter and stronger light, because they are the ones who are trying to attract males to them.(12)And different species of lightning bugs have different patterns of flashing light to attract their own species. For example, if there are five different species of lightning bugs all in the same field, they can tell who is their same species and who is not.(12)On other condition, lightning bugs light up when they see their enemies. They aim to frighten and warn the enemies by doing this. Some researchers once made experiments on mice in 1997; they confirm that light given off by lightning bugs plays a warning role on mice. This result of research is beyond people’s expectation.
