THE WORLD'S HEAVIEST INSECT

The Heavyweight champion of the insect world

What is worst than coming face to face with a creepy crawly? Coming face to face with a giant creepy crawly!

New Zealand’s Giant Weta is the heaviest insect on the planet; weighing more than 71 g, this arthropod is heavier than a swallow. There are eleven species of giant weta, which are significantly larger than other weta or any other insect. The largest species of giant weta is the Little Barrier Island giant weta also known by the Maori name ‘wetapunga’, which means ‘god of ugly things’. These heavyweights have a body length of up to 10 cm, excluding their lengthy legs and antennae. They often live under rocks and bush floor debris and prefer a vegetarian diet.

At approximately two years of age the female will lay anything between a hundred and three hundred eggs. Unfortunately, the parents of the ‘little giants’ will die before the eggs hatch three to five months later. However spine-chilling they seem, they are in actual fact gentle giants and need to be respected and protected. Weta are at risk from being eaten by rats, trampling by stock and killed by forest fires.

UNIQUE SPECIE OF 'ZOMBIE' ANTS





The Return of the Zombie Ant

Unique Characteristics:
• A Phorid fly injects their egg into a fire ant
• The phorid larvae then feasts on the brain of the ant, turning the ant into a zombie
• The baby fly decapitates its host and exits through the ants head
• In some cases the zombie fire ants will start to attack their own kind

Phorid flies in South America have a bizarre and rather cold-hearted way of reproducing. First they need to find a target, a nonchalant fire ant; they will then hover over it and inject their victim with their egg, using their needle-like appendage.

After the eggs hatch, the larvae moves to the head of the ant, feasting on it’s brain for weeks, turning the fire ant into a zombie, making it the perfect plot for a horror movie. However the movie is still not at it’s end; finally the baby fly decapitates its host and exits through the ants head. In some cases the zombie fire ants will start to attack their own kind, just as any zombie will do. Feeding ants roaming outside is more vulnerable to attack than those taking shelter in hidden nests.
