The ego-based human perception of insects and even most animals is that they are emotionless creatures that have no unique or distinct personalities within their own species. However, new studies have shown that even cockroaches have unique personalities.

According to research conducted by scientists from Brussels, Belgium, cockroaches behave very differently, even when in the same environment, due to their personality.

In the study, 304 cockroaches had RFID chips placed on their backs and were led by the scientists through a variety of settings, both light and dark. The scientists then measured how quickly the cockroaches were able to find shelter and they also recorded the time that they spent exploring and searching for food.

Through their research, the scientists found that the cockroaches would all behave differently, even when subject to the same external stimulation.

“From studying the way they find shelter, we show that individuals have consistent behavior which can differ between individuals in a group – cockroaches have personalities. Moreover, these individual personalities have an impact both on the group personality and sheltering dynamics,the study said.

We have categorized the observed personalities. We call them ‘shy or cautious’ and ‘bold or explorers,'” Isaac Planas Sitjà, one of the researchers told reporters.
