American researchers have discovered that Madagascar hissing cockroaches use group behavior as a way to protect against dehydration. Experiments showed that when humidity levels decrease, the insects tend to stay close to each other, which helps reduce moisture loss through evaporation.
In their natural environment, these cockroaches live in large colonies, so forming dense clusters is not difficult for them. This behavior helps them survive in unfavorable conditions, including during droughts. However, this strategy also has its downsides. When insects gather in groups, competition for available resources intensifies among them. Additionally, dense clusters make them more noticeable to predators.
Such changes in behavior can have broader consequences. In the long term, the concentration of cockroaches in one place can affect ecological relationships. These insects participate in the decomposition of organic remains and thus contribute to environmental cleansing.
The authors of the study note that as global warming intensifies, such a strategy may be used more frequently. This, in turn, could influence both the reproduction of Madagascar cockroaches and their role in the ecosystems where they reside.
