Jack jumper ant

This species also goes by the name of jumper ant or hopper ant. These names are not coincidental, as the ants are known to jump pretty far when in danger. They are woodland and forest creatures, but they may settle in your garden without hesitation, too.

Jack jumper ants’ life cycle

  • These ant species can have up to four queens in a colony. Despite that fact, the jack jumper worker ants can reproduce on their own even without a queen around.
  • A queen can mate with up to nine males during a reproductive period. In most cases, though, the queen limits her choice to just one or two candidates.
  • The workers in a jack jumper colony have a life expectancy of around a year. The queens, on the other hand, can surpass them significantly, reaching 10 years.

Jack jumper ants’ habits

  • They need lots of small stones and gravel to build their nest. Therefore, bushlands, woodlands and forests are the most convenient places.
  • These types of ants like to go out during the day and hunt for food, preferably in warm weather.
  • Jack jumpers enjoy a diversified diet. Honeydew is one of the things on the menu. These ants are also excellent predators and they like feasting on spiders, other ants, wasps and other insects.

Facts about jack jumpers

  • These ants have quite strong mandibles, which they use to grasp onto their victim before they sting and inject venom.
