***Allenius iviei***, known as the **enigma ladybeetle**[4] is found in the [U.S. states](/source/U.S._states) of [Idaho](/source/Idaho) and [Montana](/source/Montana). It is one of the rarest insects of the United States and was discovered in 2009. The pronotal plate of this species is very elongated, and easily conceals the head from above. The species is unique in the ability to tuck its [head](/source/Head) into its [thorax](/source/Thorax) for protection.[5]
