The three known cricket species from the park are Ceuthophilus carlsbadensis, C. longipes and C. conicaudus. As with many insects, these animals have not been given common names. Ceuthophilus carlsbadensis is found in many caves throughout New Mexico and Texas and is very common in Carlsbad Cavern. This cricket actually shows very little adaptation for living in caves and tends to live in food-rich areas, such as cave rooms with bat guano. On the other hand, Ceuthophilus longipes (known from numerous park caves) is more cave-adapted and is found in food-poor areas. C. longipes is smaller and lighter in color and has longer legs and antennae than C. carlsbadensis. The third species, Ceuthophilus conicaudus, falls between the other two species in cave adaptation traits. It is only found sparsely in Carlsbad Cavern, but is the dominant cave cricket in a few other park caves.
