Cockroaches

There are a few thousand species of cockroaches that can fly, but they usually do not fly because they are bad fliers. 

The blood of the cockroaches does not have hemoglobin, which is what give human blood the red color. Hence, their blood lacks the red color, making it appear white.

The antennas of a roach are important sensory organs. These antennas have small hairs on them that allow the cockroaches to sense the world around them and survive. The antennas help the roach detect heat, moisture, temperature, chemical consistency, etc.
