Green-Head Ant queen

The Green-Head Ant queen, found on Australia’s east coast, possesses a potent sting capable of causing anaphylactic shock in sensitive individuals. These solitary nesters establish homes in the ground or beneath rocks. 

They maintain monogamous behavior, mating only once in their lifetime with a single male while continuously laying eggs, leading to colony expansion. All workers in Green-Head Ant colonies are of the same size, a characteristic known as monomorphism. 

These queens play crucial roles in the ecosystem, controlling insect populations and serving as food sources for birds and lizards. They exhibit impressive traits, such as a lifespan of up to 10 years and the ability to lay up to 100 eggs daily, allowing colonies to grow beyond 100,000 workers.

What Do Green-Head Ants Eat?

Green-Head Ants

Green-head ants are also known as Rhytidoponera metallica have a diverse diet that includes:

  • Insects and Arthropods: Green-head ants are opportunistic scavengers. They actively forage for and feed on a variety of dead insects and arthropods. This scavenging behavior helps keep their colonies well-fed and sustains their nutritional needs.
  • Predatory Behavior: In addition to scavenging, these ants exhibit predatory behavior when the opportunity arises. They may capture and consume smaller insects and other creatures that they can overpower.
  • Consumption of Sweet Substances: Green-head ants also have a preference for sweet substances. They are known to feed on honeydew, a sugary secretion produced by aphids and certain other sap-sucking insects. These ants establish mutualistic relationships with aphids, protecting them from predators in exchange for a steady supply of honeydew.

Their dietary versatility, which includes scavenging, predation, and consumption of sweet substances, underscores their adaptability and ability to thrive in a range of ecological niches. This adaptability is crucial for their survival, particularly in environments where food resources can be scarce and unpredictable.
