Nasutitermes triodiae workers and "snouted" soldier castes

Nasutitermes triodiae, also known as the cathedral termite , is a grass-eating species of Nasutitermitinae termite that can be found in Northern Territory, Australia. It is also sometimes referred to as the spinifex termite, since it is found in the spinifex [1] (also known as Triodia) grasslands. Very little research has been done on the underground nature of this species.

Description and behaviour

Mounds

Nasutitermes triodiae mostly live in Northern Territory, Australia. They are known for their skill at building "cathedrals". Mounds of the cathedral termites on the dry plains of the Northwest Territory dominate the landscape and often tower more than 15 feet in height. [2] [3] Constructed from mud, plant parts, and termite saliva and feces, the columns of the mound are extraordinarily tough and able to withstand the rigors of wind, rain, heat, and hungry predators. Construction of the hollow columns allows for internal circulation of air from the cooler soil at the base of the mound to the warmer top. This clever ventilation provides a central air-conditioning system that enables the colony to remain relatively cool even when the external temperatures are very hot.

Defense mechanisms

When there is a breach in the nest, nasute soldiers pour out to defend the colony. [4] Termite soldier castes can be distinguished by their dark brown head and elongated, tubular snout called a nasus . The termites create and store a mixture of monoterpenes, sesquiterpenes and diterpenes which can then be ejected from their long, horn-like nasus. [5] The secretions are able to entangle, irritate and repel invaders. If a human were to stick their finger in the mound, it would be covered in the defensive fluid.

Diet

Nasutitermes triodiae often feed on Triodia, [1] which are common in the grasslands where they can be found. It doesn't matter if the plant material is living or dead. To avoid the heat and sunlight, the termites create tube-like structures of mud toward their food source. These tubes are then built around the grass, where the spinifex is then consumed. The hollow tubes left behind are used to reach the other blades of grass.

Termites are a group of detritophagous eusocial insects which consume a wide variety of decaying plant material, generally in the form of wood, leaf litter, and soil humus. They are easily identified by the typically soft-bodied and unpigmented worker caste for which they have been colloquially termed "white ants"; however, they are not ants to which they are distantly related. About 2,972 extant species are currently described, 2,105 of which are members of the family Termitidae.

<span class="mw-page-title-main">Nest</span> Place of refuge for animals

A nest is a structure built for certain animals to hold eggs or young. Although nests are most closely associated with birds, members of all classes of vertebrates and some invertebrates construct nests. They may be composed of organic material such as twigs, grass, and leaves, or may be a simple depression in the ground, or a hole in a rock, tree, or building. Human-made materials, such as string, plastic, cloth, or paper, may also be used. Nests can be found in all types of habitat.

<span class="mw-page-title-main">Mound-building termites</span>

Mound-building termites are a group of termite species that live in mounds. These termites live in Africa, Australia and South America. The mounds sometimes have a diameter of 30 metres (98 ft). Most of the mounds are in well-drained areas. Termite mounds usually outlive the colonies themselves. If the inner tunnels of the nest are exposed it is usually dead. Sometimes other colonies, of the same or different species, occupy a mound after the original builders' deaths.

The spinifex pigeon, also known as the plumed-pigeon or gannaway pigeon, is one of four endemic Australian bird species within the genus Geophaps. It occurs within a broader group known as bronzewing pigeons. This species is listed under the International Union for Conservation of Nature (IUCN) Red List category of "least concern". It most frequently occurs in arid and semi-arid habitats containing hummock-forming grasses of the genera Triodia and Plectrachne.

<i>Triodia</i> (plant) Genus of plants

Triodia is a large genus of tussock grass endemic to Australia. The species of this genus are known by the common name spinifex, although they are not a part of the coastal genus Spinifex. Many soft-leaved Tridoia species were formerly included in the genus Plectrachne. Triodia is known as tjanpi (grass) in central Australia, and have several traditional uses amongst the Aboriginal Australian peoples of the region.

<span class="mw-page-title-main">Hodotermitidae</span> Family of termites

The Hodotermitidae are a basal Old World family of termites known as the Harvester termites. They are distinguished by the serrated inner edge of their mandibles, and their functional compound eyes which are present in all castes. They forage for grass at night and during daylight hours, and the pigmented workers are often observed outside the nest. Their range includes the deserts and savannas of Africa, the Middle East, and Southwest Asia. Their English name refers to their habit of collecting grass, which is not unique to the family however.

<i>Hodotermes</i> Genus of termites

Hodotermes is a genus of African harvester termites in the Hodotermitidae. They range from Palaearctic North Africa, through the East African savannas to the karroid regions of southern Africa. As with harvester termites in general, they have serrated inner edges to their mandibles, and all castes have functional compound eyes. They forage for grass at night and during the day, and their pigmented workers are often observed outside the nest.

<i>Amitermes meridionalis</i> Species of termite

Amitermes meridionalis, commonly known as the magnetic termite or compass termite, is a species of eusocial insect in the family Termitidae. It is endemic to northern Australia and the common names derive from the fact that the wedge-shaped mound is aligned with its main axis running north and south.

Coptotermes frenchi, the Australian subterranean termite, is a species of termite in the family Rhinotermitidae. Termites are social insects and C. frenchi usually builds its communal nest in the root crown of a tree. From this, a network of galleries extends through the nearby soil, enabling the workers to forage in the surrounding area without emerging on the surface of the ground.

<i>Strophurus elderi</i> Species of lizard

Strophurus elderi, also known commonly as the jewelled gecko, is a terrestrial, nocturnal species of gecko, a lizard in the family Diplodactylidae. Previously classified within the genus Diplodactylus, S. elderi is one of 22 geckos belonging to the genus Strophurus. The species is endemic to the arid regions of central and north-western Australia.

<i>Trinervitermes</i> Genus of termites

Trinervitermes is a termite genus belonging to family Termitidae. Members are native to the Old World. They inhabit grasslands and store grass in their nests or mounds, just below the ground surface. Their grass-collecting activities are mainly nocturnal. The soldier caste has atrophied mandibles and a fontanelle squirt gun on the frons. Diterpenes and monoterpenes are released to deter ants and smaller predators, but these are not effective against larger mammalian predators. Due to the snout on the head of soldiers and their grass-collecting habits, they are known as snouted harvester termites.

<i>Triodia scariosa</i> Species of plant

Triodia scariosa, is more commonly known as porcupine grass or spinifex, and belongs to the endemic Australian grass genusTriodia. The species is perennial and evergreen and individuals grow in mounds, called hummocks, that reach up to ~1m in height. The leaves are ~30 cm long, 1mm in diameter, needlepointed and rigid, and its inflorescence is a narrow, loose panicle that forms a flowering stalk up to ~2m in height. The name is derived from Latin; Triodia refers to the three-toothed lobes of the lemma, and scariosa is in reference to the thin, dry glume. The species is common to Mallee (MVG14) and Hummock grassland (MVG20) communities, in arid and semi-arid regions of Australia.
