A nauplius (plural nauplii) is the first larva of animals classified as crustaceans (subphylum of Arthropoda). It consists of a head and a telson. The thorax and abdomen, characteristic of adult crustaceans, have not developed yet. A prominent characteristic of nauplii is that they have only one compound eye, which will divide in two in later stages. Nauplii have three pairs of cephalic appendages with which they swim; in the adult these become the antennules, the antennae, and the mandibles. The name nauplii properly refers to crustacean larvae that use appendages that stem from the head (antennules and antennae) as their main means of swimming.

"The Pyralidina are a group of small moths readily distinguished by their long slender bodies and large forewings. One of these, Pyralis vitis, is very destructive to vines, and another, Pyralis farinalis, feeds upon meal and flour. The Galleridae, a family of Pyralidine moths, deposit their eggs in the hives of bees, where the caterpillars, enclosed in silken cases, devour the wax; but the Hydrocampidae, which also belong to this section, are probably the most wonderful of all Lepidopterous insects, their larva being aquatic, living and feeding in the water, and many of them beathing by gills similar to those of caddisworms." — Encyclopedia Britanica; 1893

"The Tortricina include a great number of small moths exceedingly injurious to orchard and other trees. They are known as "leaf-rollers" from the habit which most of their larva have of rolling up the leaves on which they feed, and thus forming a shelter for themselves. The Green Tortrix occurs in the larva state on the oak, to which it often does great injurt by stripping the trees of their leaves in the month of June. Throughout Southern Europe the vine is liable to the ravages of another species, Aenectra pillariana, while few of our fruit trees are exempt from the occasional attacks of some species or other of the Carpocapsidae, the fruit-eating family of this group." &mdash; Encyclopedia Britanica; 1893
