The head of the moth is pointed downwards at the front end, so it is called hypognathus. The head is pear-shaped. The exoskeleton of the skull is called the head capsule or epicranium. It consists of six sections. However, in intact animals there is no sign of segments and appears to be a single structure. and . The dorsal triangular region of the skull is called the vertex, the posterior leaf-like portion is called the occiput, the frontal region is the frons, the lateral region is the gena, and the lower rectangular leaf is the clypeus. The appendages of the head are mentioned:
(i) Antenna: There are two sensitive antennae on either side of the head in front of the base. It is cylindrical, cylindrical, unbranched and multi-lobed. Each antenna consists of three parts. Scape, pedicel and flagellum. The base of the antenna is the scape. Pedicel short and undivided. The flagellum is long and divided into 20-25 segments. Each segment contains sensory cells and neurons. Antennae sense touch, smell and sound waves. Dr. Siddiq Publications
(ii) Compound eye: On either side of the head there are two pistils (black, convex, large) like acorns and seeds. Each punjakshi consists of numerous polygonal chambers. Each of these is called an ommatidium. Grasshoppers have better vision than any other arthropod. They can identify colors with their eyes.
(iii) Ocelli: There are three ocelli or ocelli between the two capitals. Each ocellus is composed of a lens and a cluster of photosensitive cells. Each lens is thick, clear and made up of cuticles. Sensory cells contain pigments. It contains coniagen cells, retinular cells, rhabdomes, pigmented cells and neurons. Grasshoppers sense changes in light intensity with the ocellus. Many people think that a single reflection is formed through this. Dr. Siddiq Publications
(iv) Mouth parts: The movable jointed appendages around the mouth are called mouthparts. The mouthparts of grasshoppers are called mandibular mouthparts because they are used for chewing young leaves. It consists of five parts. Labrum, mandible, maxilla, labium and hypopharynx.
