DescriptionThe Coastal Brown ant is a very successful invasive species and is considered a danger to native ants in Australia. It has been nominated as one of the hundred "World's worst" invaders The Coastal Brown ants nest in soil and build along pathways around the house including gardens and walls. They prefer dry areas for nesting. The Coastal Brown ants excavate leaving mounds along foot paths and other areas that are unsightly. They feed on meat, sweets, fruit and greasy foods. The Coastal Brown ants eggs are small in size. The larvae are fed by the adults and after several moults the larvae pupate. Once they are adults, 3 different castes exist:
- Workers are wingless and sterile that lives for approximately a year. Workers are the nest-builders, food suppliers, feed larvae, look after eggs and defend the nest.
- Males are winged and exist to mate with females.
- Females are also winged until after mating and are also the largest in size. Females become the reproductive queen of the colony and live for many years.
