In this case it is leathery in texture, not distinctly hardened and straight. Image courtesy of John Moore. Note anal cerci indicated by pointer. Geniculate Antennae. Each segment has an own set of muscles that moves it independently from the rest of the antenna. Thousands of antennae! In stylate antennae, the final segment terminates in a long, slender point, called a style. However, the rest of arthropods only have a single pair of uniramous antennae.

The 13 Forms of Insect Antennae
Insect antennae serve different sensory functions and come in 13 different forms. The segments of serrate antennae are notched or angled on one side. Insects have two antennae and these are used to sense their environment. Serrate - the segments are angled on one side giving the appearance of a saw.
Locomotion in insects is centered in the box-like thorax, which is subdivided into the prothorax, mesothorax and metathorax.

Hexapods like insectswhich seem to be closely related to crustaceans according to the pancrustacean model, seem to have just preserved the secondary pair of antennae typical of crustaceans.
Plumose (featherlike) Pectinate (comblike) Serrate (sawlike) Moniliform. Although antennae vary widely in shape and function, all of them can be divided Filiform = thread-like; Moniliform = beaded; Serrate = sawtoothed; Setaceous.
Antennae function almost exclusively in sensory perception. To serve as Serrate antennae have a saw-toothed shape.
Types of Antennae
Unlike the capitate ones, clavate antennae get progressively thicker in their ends. In raptorial front legs, the tibia is swollen or greatly enlarged. In many insects the most obvious structures on the head are the compound eyes.
Plant-feeding insects rely on smell to find food and their compound eyes typically are less well developed than are those of predators. It is thought they may serve for balance. A mantid with well-developed bulging compound eyes yellow arrow.
Antenna plumose (feathery rather than serrate), with more than 30 flagellomeres Antennae function as a complex arrangement of multiple types of receptors in. Firefly with Serrate Antennae. The maxillae function to manipulate or move the food into position to be The finger-like structure (palps) functions in taste.
Note anal cerci indicated by pointer.
Some adult insects and nymphs also possess 1 to 3 simple eyes, or ocelli, that are located on the vertex or upper front areas of the head. The term geniculate derives from the Latin genumeaning knee.

Clipping is a handy way to collect important slides you want to go back to later. In the case of blood suckers, the stylets work up and down, eventually penetrating the host and pumping in salivary enzymes which function to facilitate blood flow and possibly to serve as an anesthetic.

|The back edge of a raptorial femur typically bears spike-like structures.
Grashoppers with saltatorial hind legs. With this type of clubbed the antennae gradually enlarges towards the tip. Other legs that are modified in a specific way include saltatorial legs, where the hind femur is greatly enlarged for jumping e. The shape of the antennae is frequently used in insect identification for both order and family.
This organ is absent in non-insect hexapods springtails, diplurans.
