Cave Cixiid
A remarkable cave-adapted planthopper from Hawaiian lava tubes that has lost its eyes and wings. Its body is pale and depigmented, adapted to complete darkness.
Did You Know?
This eyeless cave-dwelling planthopper was one of the first species used to study speciation in cave systems, with different populations in separate lava tubes diverging into distinct species.
Lucifugous Springtail
One of the smallest known hexapods, found in deep soil and cave environments. It is nearly transparent and extremely difficult to observe.
