General Identification

  • Complete metamorphosis
  • Egg -> larva -> pupa -> adult
  • Eggs hatch into white, soft, legless larvae
  • Larvae molt several times before its pupae stage
  • Eventually emerging as adult ants
  • It takes 4 – 8 weeks for a complete development from egg to an adult
  • Ants are social insects where the queen lays eggs
  • Workers find food, defend and maintain the nest
  • Workers will share the food throughout the entire colony
  • This process is called trophollaxis

Fun facts

  • Since ants are social insects
  • The best measure to manage them is through baiting
  • Where the workers will then share the baits to the rest of the colony
  • Pesticides spraying against ants will create repellence to the ants
  • It can actually promote budding
  • Insects splits and some of its members depart to start a new colony elsewhere
  • The insects will simply spread out in order to avoid sprays, powders and poison
  • Ants don’t have ears.
  • Ants “hear” by feeling vibrations in the ground through their feet
  • When ants fight, it is usually to the death!
  • When foraging, ants leave a pheromone trail so they know where they’ve been
  • Queen ants have wings, which they shed when they start a new nest
  • Ants don’t have lungs.
  • Oxygen enters through tiny holes all over the body
  • CO2 leaves through the same holes
  • When the queen of the colony dies. The colony can only survive a few months.
  • Queens are rarely replaced and the workers are not able to reproduce
