[1] It is visually recognised by its characteristic pointed yellow tail and is a medium-sized moth species with a wingspan range of 40mm-60mm depending on gender.

This park is known for its biodiversity due to its soil fertility, allowing for a wide array of plant and insect species to inhabit.

[3] The soil mainly consists of Hawkesbury sandstone and Wianamatta and Narrabeen shale, which has high phosphorus content and allows for a richness of rainforest genera in flora and fauna to occur.

Some of the original type specimens they classified are deposited in The Natural History Museum (London).

He was the sole author of three publications on taxonomy and already owned the largest private entomological collection in central Europe prior to his collaboration with his son Rudolph.

[5] In the early 1860s Rudolph's talent for Entomology became apparent and began his collaborative work with his father.

Rudolph's passing in 1871 delayed the completion of the pair's most detailed publication, the Lepidoptera volume of the 'Novara Cruise'.

It includes the families of Arctiidae, Aganaidae (or Hysidae), Dioptidae, Herminiidae, Lymantriidae, Noctuidae, Notodontidae, Oenosandridae, Thaumetopoeidae, and Thyretidae.

[6] Phylogeny refers to the evolutionary lineage of a group of organisms and their lines of descent and relationships within each level of evolution (e.g. order, family, genera etc.).

Adult moths in the Noctuoidea superfamily have evolved thoracic ears to recognise the echolocation calls of nearby predator bats.

There is much debate as to how families and superfamilies in the order of Lepidoptera should be sub-classified, and recent study into differences of auditory anatomy have been proposed to discern phylogenic relationships.

As suggested by its colloquial name, this moth is defined by the tuft of yellow hairs extending from its tail region.

Studies done on captive Larvae of this species show that larvae will consume mature, drier leaves of eucalyptus including eucalyptus odorata and are purely nocturnal feeders once past the initial instar stages (stages of moulting in the process of sheding the exoskeleton on the way to reaching adult moth form).

After the first dispersal, they will still exhibit socialising behaviours (resting closely together with other moths when taking shelter in the day) when smaller, but become solitary creatures once reaching full maturity.

Adults will take flight around mid November to march, with peak periods in late December to early February.

The male has light brown forewings freckled with closely distributed black spots and white hindwings.

[12] Discophlebia Lucasii has evolved to mimic the appearance of a branch stub where parts have broken off.

This is apparent as the pale grey head of the moth appears to be a stub on a branch where the twig segment has snapped off.

At rest, this moth physically resembles the green-faced gum hopper (Platybrachys decemmacula).

This species is found all over southern regions of Australia including parts of QLD, NSW, ACT, VIC, and WA.

Original notes by Rosenstock in 1885 contain detailed descriptions of the moth's wings, uppersides and undersides.

Its hindwings are a pale, whitish colour near the body and have a darker brown band along the outer edges.

Its hindwings are of a pale colour with veiny lines running from the body to the wing's edges.
