|This is a 3rd instar, or "L3" larva of
tityus. Touch is perhaps the most important sense to the larval
stage of D. tityus, and it has numerous tactile hairs along its
body which help it to determine its position and what it is in contact
with. Being a dweller within the darkness of decaying logs, sight
is of little importance to it. Unlike the adult beetle, it has rather
simple eyes (called "ocelli") which are probably only able to determine
between light and dark, rather than form any kind of actual image.
