Proposed changes among non-threatened categories LC, DD and NE in the NT – Invertebrate animals

We have very limited knowledge of the distribution and abundance of most species of invertebrates in the NT, which number more than 10,000 species (many unnamed).

The table below lists the species of invertebrates previously listed as Data Deficient (DD).

Following discussions with prominent entomologists, the current review proposes to remove these species from the Data Deficient list as this classification is appropriate for the majority of invertebrate species.

Most of these species have been reclassified as Not Evaluated (NE) in this review, which is the classification currently applied to most invertebrates in the NT.

The eight remaining DD species have been reclassified as Least Concern (LC) or Not Assessed (NA).

In addition, two species of butterfly that were previously classified as Least Concern have been reclassified as Not Evaluated in the 2020 review:

  • Eurema brigitta No-brand Grass-yellow – known from only one record in the NT.
  • Pelopidas agna Common Swift – records of this species are now considered to refer to Pelopidas lyelli.

Species of invertebrates that were previously listed as threatened or near threatened (mostly species of butterflies and land-snails) will retain their current status.
