Fun facts
The skin rash often comes in a line, because people brush the beetle off and drag it across their skin.
The rash does not show up right away. It appears a day or so later.
It flies in the daytime and is drawn to bright lights at night.
There are more than 400 kinds of these beetles around the world.
