We all have spotted those perky little antennas coming from a mile away and ran off screaming: COCKROACH!!
Don’t they look like aliens with those huge antennas on the top of their heads?
But have you ever wondered why does a cockroach even has an antenna? If yes, then today is your lucky day because we just happen to know the answer!
Yes, antennas (also known as antennae by their scientific name) are an integral part of a cockroach’s anatomy.
This part of their body has different functions and in this article, we want to let you know what 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 attaches the antenna to the head and allows it to move- scape and pedicel, and the third is the flagellum.
The flagellum is that long slimy 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 small hairs that scientists know as the sensillae.
As the 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 their 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 cockroach antenna responsible for sensing the world; the scape and pedicel also have similar functions.
The scape and pedicel also have small hair called sensillae that help the cockroach sense the position they’re in and the movement they’re about to make next.
Furthermore, the scape and pedicel are responsible for informing the cockroach about the state of its flagellum.
The antennas are located on the head of the cockroach.
This part of the body also holds important organs such as the eyes 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: why are cockroaches so difficult to get rid of?
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, set up roach traps in various places all over your house, etc.
To conclude, every cockroach has two antennas; these are divided into three specific parts: scape, pedicel, and flagellum.
The scape and pedicel keep the antennas attached to the cockroach’s head, but they also help the cockroach know its position and the next move they make.
The flagellum has 150 segments, and it’s covered with sensillae which helps the cockroach smell and feel its surroundings.
