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.
What Kind of Plants Do Fireflies Live In? The firefly crawls up tall blades of grass to get into a flying position. It's essential summer magic: spotting the bright flash of the firefly (Photinus spp.) in the garden at dusk. But as is the case with so many other elusive and mysterious creatures of nature, firefly populations are diminishing around the globe, victims of encroachment and human light pollution.
