Mammoth Cave Beetle
A rare troglobitic ground beetle known from caves in the Ozark region of Missouri. It is eyeless with greatly elongated appendages.
Did You Know?
It was not discovered until 1987, despite extensive surveys of Missouri caves.
Yellow-banded Eucalyptus Longhorn
An Australian cerambycid similar to P. semipunctata but with more pronounced yellowish bands and recurved elytral apices. It has also become invasive worldwide in eucalyptus plantations and often outcompetes its congener.
Did You Know?
Where both Phoracantha species co-occur, P. recurva often displaces P. semipunctata through larval competition.
