Tetracis australis
This record describes Tetracis australis (species). Recorded family: Geometridae. Recorded order: Lepidoptera.
Identification and Appearance
Currently (2022) the BOLD ( 4 ) specimens in this genus seem to be split, mixed up or duplicated with Synaxis and Tetracis . (see here and here ) It isn't clear why they are using both genera. See also - Specimens of Synaxis brunneilinearia (old name) from southern California: see here (Bin #: BOLD:AAA6040 includes several species) -----> That old taxon name was moved or corrected to Metanema brunneilinearia in the 2010 revision. ( 3 ) Inaturalist has Synaxis listed as an inactive taxon. (worldwide) ( 5 )

About Butterflies and Moths: the wider group
Order-level background for Lepidoptera, the group containing Tetracis australis. Species-specific details appear above.
Group overview
Lepidoptera includes approximately 180,000 described species of butterflies and moths. Moths outnumber butterflies roughly 10:1. The monarch butterfly's eastern population has declined by more than 80% since the mid-1990s, and the western population by over 95% since the 1980s. The IUCN lists the migratory monarch as Vulnerable.
Ecological role of the group
Butterflies and moths are essential indicators of ecosystem health. As caterpillars, they are a primary food source for birds - a single nest of blue tit chicks requires ~10,000 caterpillars. Adult moths pollinate many night-blooming plants.
Economic and practical significance of the group
Lepidoptera are critical pollinators. In Europe, grassland butterfly species have declined by almost 50% since the early 1990s. In the UK, three-quarters of butterflies are in decline. In the U.S., five butterfly species have gone extinct since 1950, with 29 listed as endangered.
