What insect has Setaceous antennae?
Setaceous antennae are bristle-shaped and tapered from the base to the tip. Examples of insects with setaceous antennae include mayflies (order Ephemeroptera) and dragonflies and damselflies (order Odonata).
What are the types of insect antenna?
Types of Antennae
- Filiform = thread-like.
- Moniliform = beaded.
- Serrate = sawtoothed.
- Setaceous = bristle-like.
- Lamellate = nested plates.
- Pectinate = comb-like.
- Plumose = long hairs.
- Clavate = gradually clubbed.
Which structure never occurs on an abdominal segment?
gonopore
Paired abdominal appendages (slender styles or short pegs) can be found in only the most primitive insects. These appendages are probably remnants of myriapodan legs. The external opening of an insect’s reproductive system, the gonopore, never occurs on the last abdominal segment (as in other hexapods).
What are antennae on insects for?
Insects do this with the pair of antennae on their heads. But insects don’t only use their antennae to smell. They can also use them to feel the surface of an object, sense hot and cold, listen to sounds or detect the movement of air or wind. Insects have paired antennae so they can smell in stereo.

Do insects smell with their antennae?
Insects “smell” with their antennae. Pheromone-binding proteins (PBP) pick up pheromones at pores in the outside of the antenna and carry them through a watery layer to the nerve endings, where they are released.
What are insect antennae made of?
Antennae are connected to the first one or two segments of the arthropod head. They vary widely in form but are always made of one or more jointed segments. While they are typically sensory organs, the exact nature of what they sense and how they sense it is not the same in all groups.
What is cockroach antenna?
The antennae are used as a way to sense the world around them. Roaches use their antennae to locate food and estimate the distance and height of any obstacles in front of them. They can also detect pheromones, enabling them to find mates. If a cockroach loses its antennae, it will be more vulnerable to predation.
