Well FC is for all the clubs I think since it means Football Club. United is just a part of the name. For example there are 2 Manchesters, one is united and the other one-city. The same is about real and red.
In general, most of the Eastern half of the United States gets fireflies. Fireflies generally live in suburban or rural areas; cities are so bright at night they can't see each other's lights to find a mate. The larva do best near water; they live in wet rotting wood and eat slugs and snails that live in moist areas. Adults hide in long grass or bushes during the day. So usually, the best places for fireflies are where a forest or field meets a water feature - swamp, stream, pond, etc. Written Sep 13, 2014.
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.
