It is also resistant to wildlife browsing due to its unpalatability. Their bright coloration advertises unpalatability to potential predators. These moths are aposematic and use their bright coloration to warn predators of their unpalatability. The plain tiger is mimicked by several species due to its unpalatability to potential predators. Its flight and bright colouration advertise its unpalatability. This species is inedible due to its toughness and unpalatability; it is usually bitter. Unpalatability, broadly understood, can be created in a variety of ways. To advertise their unpalatability, the butterfly has prominent markings with a striking colour pattern. Adults indicate their unpalatability with clicks from their tymbal organs (Simmons and Conner 1996). Queen unpalatability does not directly mirror either food plant or butterfly cardenolide content. Such unpalatability is advertised using bright red, orange, black, or white warning colors.
