Cockroach Antenna: Do Roaches Have Antennas?

We all have spotted those perky little antennas coming from a mile away and screaming: a cockroach! Don’t they look like aliens with those huge antennas hanging from each side of its head?

Yes, antennas (also known as antennae by its scientific name) are really characteristic part of a cockroach. This part of their body have different functions and in this article, we want to let you know which are those functions. But first, let’s talk about the parts of an antenna.

Everything about Cockroach Antennas

The antennas of a cockroach are divided into three specific parts: the first one that attached the antenna to the head and allows it to move (scape and pedicel), and the flagellum.

The flagellum is that long a slim part of the cockroach we see coming from a mile away. Why are they so long? Because these parts have 150 segments that, together, form the flagellum.

This part of the antenna is covered in many pieces of small hair that scientists know as the sensillae. As its name implies, these small hairs are responsible for letting the cockroach know what’s around them; these insects smell, feel the humidity, pressure, and temperature through its antennas, and how can the sensillae do this? These small pieces of hair are connected to specific parts of the nervous system of the cockroach.

The flagellum is not the only part of the antenna responsible for feeling the world: the scape and pedicel also have this function. The scape and pedicel also have small hair called sensillae that help the cockroach in sensing the position they’re in and the movement they’re about to make next. Interesting right?

Furthermore, the scape and pedicel are responsible for informing the cockroach about the state of its flagellum.

The antennas are located in the head of the cockroach. This part of the body also holds important organs such as the eyesight and the mouthparts of the insect.

On the back of their bodies, cockroaches have sensory organs too, and we are adding this information because you might have asked yourself at some point: what are cockroaches so difficult to catch?

The answer is simple: they can sense almost every movement that’s going on behind them and, thanks to their antennas, they can decide where to go next, but they’re not indestructible!

There’s always a plausible solution for preventing an invasion or getting rid of this pest, such as: get an exterminator, clean your house every day, and try to fix holes and cracks your house might have.

To conclude, every kind of cockroach has two antennas. These antennas are divided into three specific parts: scape, pedicel, and the flagellum.

The scape and pedicel keep the antennas attached to the head of the cockroach, but they also help the cockroach know its position and the next movement it can make. The flagellum has 150 segments and it’s covered with sensillae; the sensillae helps the cockroach to smell and feel its surroundings.
