Scutella is a solitary animal and has no ability to communicate with her peers. However, they will respond to their partner's breathing, so if a scutiger is killed, its partner may be attracted by the killed scutiger. In addition, the dragonflies will release a special smell during the breeding period, attracting male dragonflies to mate. Therefore, if a female scutiger is killed, its special smell may be released continuously, thus attracting more male scutiger.
In short, although dragonflies are solitary animals, they will respond to the breath of their companions. Killing a dragonfly may attract the same kind. Therefore, direct contact with dragonflies should be avoided as far as possible, and appropriate measures should be taken to prevent them from entering the home.
