English: ‘Ūhini nēnē pele, or dark lava cricket (NPS Photo/D. Boyle) The dark lava cricket (‘ūhini nēnē pele) is a specialized species found nowhere else in the world except on the young flows of Hawaiʻi Island. They have been known to move into recent pāhoehoe lava flows as soon as a month after lava has solidified. They are not known to inhabit lava flows older than 20-100 years old. The insect will emerge at night under the cover of darkness to feed on windblown debris that gathers in cracks and crevices in the lava flow. But don't expect to be serenaded by these creatures of the night. The wingless crickets do not have the equipment necessary to make the classic cricket “chirping” sound.
