Except in Antarctica, lightning bugs can be found all over the world. According to scientists, there are about 2000 separate lightning bug species in the world. During the summer, this is a popular sight. Lightning bugs prefer a wet, moist climate and are typically found in Asia and America's humid regions. They can be found in damp areas that retain moisture, such as forests and open fields, particularly near streams, lakes, rivers, and ponds, in drier regions.
