Caconemobius is a genus of crickets in the subfamily Nemobiinae. There are about 15 species distributed from the Pacific coasts of Asia to Hawaii, where they occur in marine environments on the shores of the Pacific Ocean, barren lava fields, and lava tube caves.[1][2]

These are wingless crickets that do not sing. They have bulbous abdomens. They live among rocks on beaches and other marine environments, where they may swim and dive in the saline waters.[2]
