Similarly, winged males fly and search for their queen to mate with before they die.

Bulldog ants are found in forests, heaths, and woodlands. They build their nests underground. Biologists have found now that it is the structure of the eyes that show variations in bull ants of the same colony. They researched four different species of bulldog ants living in eucalypt forests.

At a certain time of year, bull ants grow their wings. The winged male usually dies soon after mating the queen. The wings of the queen bull ant fall off soon after mating. The fertilized queen bullet ant digs nests where she lay her eggs and spends entire life laying eggs in the nest.

Usually, an ant’s reproductive cycle has four stages: egg, larva, pupa and adult. The hatched eggs grow into small worker ants. The fertilized eggs become female bull ants while unfertilized becomes males. The queen bull ant goes out of the nest at the time of night to bring food for the babies. Their young larvae feed on dead insects.

The lifespan of a bulldog ant ranges between 8-10 weeks while passing through the all four stages of life. Nevertheless, queen bull ant usually live up to several years.
