Cave salamanders feed on flatworms, crustaceans, and insects as well as surface organisms near moist rocks near the entrance. Cave Crickets are perhaps the most abundant insect which dwells within caves. Swarms of crickets may live on ceilings and any horizontal surface. The bodies tend to be around 5 centimeters long, yet they tend to be about 15 centimeters long. This is due to the elongated antennae which are used to feel around the dark cave.
Crickets migrate into the depths of caves and mate in the sandier areas.
The long antennae also allow them to sense air currents that carry odors that could lead them to find food. Millipedes often burrow in cave silt and feed on humus and certain fungi. Cave millipedes tend to have less body pigments, thinner shells, longer legs and antennae, fewer eye facets, and longer sensory bristles than surface forms. Cave millipedes can live anywhere within the cave their is moisture. Earthworms also burrow in the mud of caves and are exactly the same as surface species.
