Palpi smooth, slender, much longer than the breadth of the head; third joint setiform, shorter than the second. Antennae smooth, slender. Hind tibiae fringed. Wings rather broad. Fore wings slightly rounded at the tips; fringe tipped with ochraceous; exterior border nearly straight, slightly oblique. Length of the body 4 ½ - 5 lines [9.5 – 10.6mm]; of the wings 13-14 lines [27.5 – 29.6mm].

Male. Closely allied to C. placidella. Silvery white. Head above about the eyes, palpi, antennae, legs and costa of the fore wings ochraceous. Third joint of the palpi white, shorter than the second. Abdomen very slightly tinged with yellow, cinereous beneath. Fore wings dark cinereous beneath, except the fringe, which is slightly tipped with ochraceous.

Subsequent description, Meyrick 1890
Xyl. luteotactella, Walk.
(Cryptolechia luteotactella, Walk. 750; C. cognatella, ib. 751.)
Both sexes 17-26 mm. Head white, sides of face broadly orange. Palpi orange, terminal joint white. Antennae ochreous-whitish, base orange. Thorax and abdomen white, anal tuft ochreous-tinged. Legs orange, posterior tibiae white. Forewings elongate, moderate, costa slightly arched, apex obtuse, hind margin straight, rather oblique; shining snow-white; costal edge narrowly orange, sometimes slenderly blackish towards base: cilia white, terminal third orange from below apex to above anal angle. Hindwings grey-whitish, posteriorly suffused with light grey; cilia white.
Sydney and Blackheath (3,500 feet), New South Wales; Melbourne, Victoria; in November, December, February, and March, common, especially in the larval state. Larva 16-legged, stout, cylindrical with scattered long hairs; whitish-grey, with subdorsal, spiracular, and subspiracular rows of large circular black spots, two on each segment; second segment ochreous-brown, with similar spots; head chestnut-brown, shining, forehead black: feeds on Lambertia formosa, Hakea acicularis, Persoonia lanceolata, Banksia latifolia, and probably many of the Proteaceae, making firm broad galleries of silk and refuse amongst twigs, sometimes with a tunnel for retirement in the seed-vessels or midrib of leaves when suitable, gnawing the bark and leaves, in September, October, and December.
I know Xylorycta luteotactella occasionally to reside in a tunnel in stems of Banksia integrifolia, though usually spinning galleries amongst twigs and leaves, and finally forming a cocoon. (Illidge, 1895).

Neodrepta luteotactella, Walk. (Cryptolechia luteotactella Walker, 750; C. cognatella, ib. 751 Xylorycta luteotactella, Meyrick, 61.) Brisbane: Mr. Illidge finds the larvae usually between spun-together leaves of Banksia integrifolia, occasionally tunnelling the smaller stems. Also from Ballandean (2,500 feet) near Wallangarra. (Turner, 1898).
Pl. 33, fig 6, Tillyard 1927
Of smaller species we may mention Neodrepta luteotactella Walk. (pl. 33, fig. 6) with smooth silky white forewings; (Tillyard, 1926).
Fig 77: Philpottt, 1927
In Neodrepta [luteotactella] the third segment [of the maxillary palp] is elongate, curved and medially constricted, having all the appearance of being the result of the fusion of the third and fourth. (Philpott, 1927.
The larva of N. luteotactella (Walk.) lives either in a webbing shelter amongst twigs and leaves or in a short tunnel in a twig or the woody fruits of Proteaceae, including Banksia and Hakea, and is a pest of Macadamia. (Common, 1970).
Fig 23.10: Xylorycta luteotactella
The smaller species X. luteotactella (Walk.) (Fig 23.10) is shining white with the costa of the fore wing yellow. It is found in Eastern Australia from Cooktown to Victoria, and is often a pest of native Protaceae grown commercially or as ornamentals (Wallace 1974). Its larva sometimes lives in a small tunnel it bores in a branch of the food plant, covering the entrance with a web of silk and faecal pellets, but more usually in a silk gallery spun among the foliage associated with webbing and faecal material. The food plants include Macadamia, Banksia, Grevillea, Hakea, Telopea, Lambertia, Persoonia, Oreocallis, and even the introduced South African Leucodendron. (Common, 1990).
135. Xylorycta luteotactella (Walker, 1864) and X. cognatella (Walker, 1864) were published simultaneously. Priority was given to X. luteotactella (Walker) by Meyrick (1890a) as first reviser. (Common, 1996).
There are indications that other termatophylines feed on moth larvae. Kundakimuka queenslandica feeds on the xyloryctine moth, Xylorycta luteotactella (Walker), which feeds on a paperbark species, Melaleuca integrifolia. ...
The association of Termatophylina Indiana with moth larval galleries, suggests that termatophylines may be commonly encountered in sheltered microhabitats. The prey of Kundakimuka queenslandica, Xylorycta luteotactella, is also known to live in small tunnels, which the moth bores in the branches of their food plant (Common 1990). (Cassis, 1995).
