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.
Giant Nicoletiid
A cave-dwelling, blind silverfish relative found in Texas caves. It is completely unpigmented and white, with elongated appendages adapted to cave life.
Did You Know?
Cave-adapted silverfish like this species represent some of the most ancient lineages of living insects still inhabiting their ancestral habitat type.
