Life Cycle of Bicolored pennant ant
Egg The embryonic bicolored pennant ant is barely visible to the naked eye. A small, oblong shape characteristic of this stage, its function is purely developmental, primarily focused on growing and transitioning to the larval stage.
Larva The larva of bicolored pennant ant resembles a segmented worm. It significantly varies in color and size from the adult, with a soft body and no limbs, consuming large amounts of food to fuel rapid growth.
Pupal Transitioning into the pupal stage, bicolored pennant ant stops feeding and remains relatively motionless. Encased within a protective cocoon, it undergoes a drastic transformation, rearranging its body structure in preparation for adulthood.
Adult Emerging from the pupa, the adult bicolored pennant ant’s development is marked by the presence of wings and functional reproductive organs. The body is fully formed and hardened, and the adult is mobile, focusing on reproduction.

Are Bicolored pennant ant harmful to humans?

Different kinds of ants cause different troubles to humans. To be sure, compared with other dangerous creatures, common ants are very harmful to humans, and most of them just gather in the courtyard or room to disturb human life.

Toxic to Animals

Bicolored pennant ant typically causes mild discomfort through its sting, impacting both larger organisms like humans and pets, as well as smaller creatures such as other ants and arthropods. In adult form, bicolored pennant ant utilizes its sting both aggressively and defensively, injecting a mild toxin that can result in localized pain and irritation. While the effect on humans and larger animals is generally limited to short-lived discomfort, smaller animals may experience more pronounced reactions due to their size relative to the amount of venom delivered.
