Why roaches are extremely hard to catch?
Published on uHandy blog
Cockroaches are perhaps the most common insects that we see in our everyday life (that’s very sad, I know), which makes them a perfect candidate to observe under a microscope. However, the first thing you have to do is to conquer your fear of getting one.
When you take it apart and get close enough to all the parts on a cockroaches, you will discover a bunch of amazing physical characteristics. Let’s see how it looks like under a microscope:
In this video, we picked up three parts of the roach — antennae, legs, and wings — to be observed under the uHandy microscope.
As we know, roaches are insects. And all insects have three pairs of legs. So do roaches. Everyone knows that roaches are extremely hard to catch. The secret lies in their legs. As you can see in the video, there are thousands of tiny hairs on their legs. These hairs can detect even the slightest movement in the air. So when human try to hit the cockroaches, they already detect our movements before we reach to them and make the successful escape.
Antennae play a key role for perceiving chemical objects. In other words, roach’s antennae work like human’s nose. The antennae enable roaches to feel and smell the world around them. As we can see under the microscope, antennae are made up of many small segments with thousand of tiny hairs. These all help to collect more chemicals in the air.
Roaches have two pairs of wings, forewings, and hindwings. Both pairs of wings are used to fly. Forewings are also known as tegmen, which are stiffer and act as a protection to the hindwings. If you dare to hold a living cockroach, you will be able to see its hemolymph (aka. insect blood), travels through the blood vessel under the microscope. Yep, I admit that I dare not to hold a cockroach alive so there’s no video of blood flow to show you all.
Even cockroaches are equipped with all these smart sensory systems to help them escape, we still managed to catch one for the video. So human claimed the victory this round we said.
