Your abdomen extends from below your chest to your groin. Some people call it the stomach, but your abdomen contains many other important organs. Pain in the abdomen can come from any one of them. The pain may start somewhere else, such as your chest. Severe pain doesn't always mean a serious problem. Nor does mild pain mean a problem is not serious.
For other uses of Firefly, see Firefly (disambiguation). The Lampyridae are a family of insects in the beetle order Coleoptera. They are winged beetles, commonly called fireflies or lightning bugs for their conspicuous use of bioluminescence during twilight to attract mates or prey.
By Laura Klappenbach. Fireflies, also known as lightning bugs, glow to lure prey, discourage predators, and most importantly to attract mates. The characteristic green-yellow glow produced by a firefly is the result of a chemical reaction that takes place in the insect's abdomen.irefly larvae are capable of bioluminescence like the adults. For this reason the larvae are sometimes referred to as glow worms. The various species of fireflies belong to the Family Lampyridae, a group of insects that in turn belongs to the Order Coleoptera, the beetles.
