In 2001 the discovery of a colony of Lord Howe Island Stick Insects living on Balls Pyramid, near Lord Howe Island, received international publicity. This species, originally very common on Lord Howe Island, had been thought to be extinct until rockclimbers, in 1964 and 1969, found evidence that it was still surviving on Balls Pyramid. In 2001 the Balls Pyramid colony was observed eating the leaves of a Tea-tree Melaleuca howeana which is endemic to Lord Howe and adjacent islands.
The local name of this Melaleuca species was first published in 1869: “A shrubby Melaleuca, inhabiting rocky exposed situations near the coast on the south-western side… locally called kilmogue, is used as a substitute for tea and said to be a pleasant and exhilarating beverage.” (Hill 1869:7; Moore 1870:9).1 When Maiden recorded the local vernacular names of plants and trees on Lord Howe Island in the 1880s, only two had non-English names. These were the Melaleuca, still known as kilmogue and Elaeodendron curtipendulum, a large tree also found on Norfolk Island and New Caledonia, which was known as tumana (Maiden 1898). The Melaleuca was still known as kilmoke in the 1930s (Nicholls 1938:90).
