Why you should visit the Termite Mounds of Litchfield

Nestled in the grass fields of Litchfield National Park are the incredible termite mounds. They are the natural sky-scrapers of the world, standing tall in the dry desert land of Litchfield. It’s no wonder that these termites are named the architectures of the animal kingdom, with the large dirt mounds being imposing, spectacular, and of course intriguing to all that see them.

About the Termites

Although these insects look similar to ants, they are in a completely different species group. They are social creatures, building their homes together to hold hundreds upon thousands of termites together. Their non-reproductive forms never develop wings, are completely blind, and have very thin skin which leads to them drying out often. In comparison, the King and Queen, which are the reproductive forms of termites, have wings, one pair of compound eyes, and thicker skin. The reproductive system is different from ants, with instead of one queen with multiple males, it is many queens in each mound paired with kings in a monogamous pairing. The non-reproductive creatures are soldiers and workers, which help in protecting and building their home.

How do they make these mounds?

The mounds are built by the workers of the colony, built from soil brought from beneath the ground. The soil is cemented together to form strong dirt with the insects’ saliva and excreta. They are tall, thin, wedge-shaped structures with the longer axis orientated from north to south.

Why do they build these mounds?

It is to put it simply; mounds are the termite’s home. However, the reason why these mounds line up so perfectly with each other is a puzzlement. Scientists believe the shape of the mounds might be to promote a quicker dry during nest construction. Others suggest the long shape of the mounds was a way to avoid winds. However, the most likely theory is due to the termites avoiding the temperature induced by the strong tropical sun. As the termites are not able to retreat underground due to Northern Australia’s heavy monsoonal rains.
