All phasmids possess compound eyes, but ocelli are only found in some winged males. Insect Identification. Filiform antennae are seen in a wide variety of groups, such as Dragonflies, Grasshoppers and Crickets, Book Lice, Biting Lice, Scorpion Flies and Beetles. The three basic segments of the typical insect antenna are the scape or scapus (base), the pedicel or pedicellus (stem), and finally the flagellum, which often comprises many units known as flagellomeres. There are many different kinds of insects. 1) OBTECT: Various appendages of the pupa viz., antennae, legs and wings pads are glued to Different bug types are included in the order Hemiptera. Some of these bugs are called biting bugs and can bite with the help of a proboscis. Although antennae vary widely in shape and function, all of them can be divided into three basic parts: scape — the basal segment that articulates with the head capsule; pedicel — the second antennal segment; flagellum — all the remaining “segments” (individually called flagellomeres) insects, have the students study different types of insect characteristics. 6. Types of Antennas. It is NOT the primary means of moving oxygen and carbon dioxide. Antennae are movable sensory organs on the head of most arthropods. All insects have a pair of antennae, but spiders have none. Insect antennae are segmented, and usually located above or between the eyes. dipole. The segments of flagellum are taper towards apex.

The pedicel (the second segment) contains the Johnston's organ which is a collection of sensory cells. Antennas act as converters between conducted waves and electromagnetic waves propagating freely in space (see Figure 1). Structure and modifications of insect antennae, mouth parts and legs. They have an exoskeleton on the outside. A 1990 count revealed 8,800 species of ants The density of the antennal sensilla increases from the proximal to distal ends, where various types of sensilla Some of these modifications just provide greater surface area for sensory receptors, while others are unique adaptations that bestow special sensory capabilities, such as detecting sound vibrations, wind speed, or humidity. 7a. recognized group of social insects. Let’s learn more about these cool critters. Six or seven segments are condensed to form the head capsule. Lamellate = nested plates. Small-scale bioacoustic sensors, such as antennae in insects, are often considered, biomechanically, to be not much more than the sum of their basic geometric features. In the first type the antenna consists of a variable number of segments, each having intrinsic musculature. There are three main types of pupae. Grasshoppers, katydids, crickets, cockroaches, etc. 7.

Some of the information that can be detected by insect antennae includes: motion and orientation, odor, sound, humidity, and a variety of chemical cues. ARISTATE Aristate antennae are pouch-like with a lateral bristle. Antennae function almost exclusively in sensory perception. A good example is that cockroaches moving along a wall can use an antenna to measure the distance between the body and the wall, thus avoiding collision (Camhi and Johnson, 1999).Blind cockroaches walking toward an object use the antennae to determine object location (Okada and Toh, 2000).Cockroaches also can use the antennae to identify and react to a small predator (Comer et al., … The half-wave dipole, also called a doublet, is formally known as the Hertz antenna.

Odorants provide insects with crucial information about their environment and trigger various insect behaviors. Stoneflies are old order of insects undergoing incomplete metamorphosis. Their name is borrowed from zoology, in which the Latin word antennae is used to describe the long, thin feelers possessed by many insects. However, they are all alike in certain ways. Therefore, little is known about the fine structure and material properties of these sensors—even less so about the degree to which the well-known sexual dimorphism of the insect antenna structure affects those properties. the insect is incapable of feeding and is quiescent. They’re also quite variable in appearance, making them an excellent identification tool. Ants are social insects. These dipole-array antennas reduce in size from the back end to the front end.
