Abstract
In 1921, Scutellista caerulea was imported and released in Nelson, New Zealand, for the biological control of pest scale insects. It was thought to have failed to establish, and is therefore currently considered to be absent from the New Zealand fauna. On 17 April 2013, a live specimen was captured in the wild in Auckland.
Highlights
In 1921, Scutellista caerulea (Fonscolombe, 1832) was released in Nelson, New Zealand, for biological control of pest scale insects, but apparently failed to establish (Dumbleton 1936, as S. cyanea)
It is not considered to be present in New Zealand, and is not listed on the New Zealand Organisms Register (NZOR)
I recommend that S. caerulea be added to the New Zealand Organisms Register (NZOR) as exotic, present in the wild
