TERMITE IDENTIFICATION & COLONY BIOLOGY
Australia has many termite species, but only a minority are important structural pests. Termites are social insects that live in colonies with specialised roles, and different species can vary in nesting behaviour, appearance and their relevance to buildings.
For property owners, the most important point is that species should not be guessed from timber damage, colour or a phone photograph alone. Identification may require the soldier caste and other colony or nest characteristics. If termites are found in a building, the practical priority is to avoid unnecessary disturbance and arrange a property-specific assessment.
SYDNEY SPECIES STARTING POINT
A widespread native Australian termite and one of the country's important building-damaging species. CSIRO notes that Coptotermes colonies can be large and that nests may occur underground, in stumps, hollow or living trees and other protected sites.
Read the species guide →A tree-nesting termite found in eastern Australia and Sydney coastal bushland. NSW educational material notes that it is mainly associated with stressed trees, dead wood, poles and timber on the ground and only rarely attacks buildings.
Read the species guide →We are deliberately publishing only profiles that can be supported cleanly by authoritative Australian/Sydney sources. Additional species, including other subterranean termites encountered in NSW, should be added only after the identification and distribution details are verified against suitable technical references.
HOW A COLONY WORKS
Workers, soldiers, queens, kings and winged reproductives perform different functions inside a colony.
Understand the castes →Workers distribute regurgitated or hind-gut food to other colony members through social food transfer.
How termites feed each other →Termites develop through egg, nymph and adult stages rather than passing through a pupal stage.
Read the life-cycle guide →Winged reproductive termites leave established colonies under suitable conditions to attempt to form new colonies.
Flying termites in Sydney →Sheltered mud-like runways can be evidence of subterranean termite movement, but should be interpreted in context.
Termite mud tubes →Construction details, hidden entry points, soil contact and moisture conditions can all influence termite access.
Entry pathways →Workers are generally pale, soft-bodied and vulnerable to drying out. They gather food, feed other colony members, tend young and help construct and maintain the nest.
Soldiers are specialised for defence and their head and defensive structures can be particularly useful during identification. Australian Museum guidance notes that termite identification can require close examination of these features.
Reproductive termites have two pairs of similar-sized wings and a more durable body than workers. They shed their wings after mating.
Termites do not have the narrow waist of ants. Their antennae are bead-like, and winged termites have two pairs of wings that are similar in size.
