Fam. BOMBYX. Sec. CRYPTOPHASA.
Cryptophasa Rubescens. Pl. 12.
Bombyx Cryptophasa with yellowish clay-coloured anterior wings, the male having a lighter marking part down the anterior margin, an ablong [sic] mark of the same near the shoulder environed with red: anterior wings of the female pale, and tinctured with rose colour: posterior wings orange-yellow: abdomen with a square mark of red at the base: the whole insect smooth and glossy.
This is a noctivagant, and provident insect in the larva state; its habits and manners differ little from the preceding species [C. albacosta]: our specimen had formed a lodgment in the stem of the Mimosa Ensifolia, as shewn in the plate, having its entrance secured by a covering fabric of excrement, which it webbed down close when within, but left unfastened the leaves it had brought for food, in its nightly excursions. The leaves of this tree are lanceolate and of such a length, as to preclude the possibility of being taken wholly within, the greater part of the leaf therefore is left out, and the larva hawls them in gradually as he consumes them: being full fed it changes to a pupa within this dwelling-place. Remains in this state thirty-eight days, and is on the wing at the end of February, when it inhabits banks of rivers, ponds, and deep gulleys or abrupt valleys; in which situations those trees are also found. The larva cutting off a leaf is shown at 1; the pupa in the wood at 2; the female moth at 4; and the male at 3.
OBS. On the stem of the tree figured in the plate is seen a round hole, and a scar below it, the work of some predecessor of this wood-boring moth. It is thus that trees have their trunks and timber perforated and exposed to bleedings and decay, by a tribe of seemingly insignificant insects, in New South Wales.

La chenille est un peu velue, d'un brun terreux, avec la tête, le premier anneau et toutes les incisions noirs. Elle vit sur le Mimosa ensifolia.
Subsequent description, Duncan 1852
C. rubescens — Anterior wings yellowish-clay coloured, tinged with rose-colour; posterior wings orange-yellow; abdomen with a square mark of red at the base. Expansion, female two inches; male, an inch and a half.
Lewin, pl 12.
The larva is a nocturnal feeder, like the rest of this tribe, and does not differ much in its habits from the preceding species. It lodges in the stems of the Mimosa ensifolia, having the entrance to its gallery secured by a covering of excrement, which is held fast, when the inmate is within, by a web. The leaves of the mimosa are lanceolate, and of such a length as to preclude the possibility of being taken wholly within; the greater part of the leaf therefore is left out, and the larva hauls them gradually
in as it consumes them. The pupa state continues for thirty-eight days, the moth appearing in the end of February. It frequents banks of rivers, ponds, and deep gulleys; these being the place when the trees it feeds on are usually found.

Crypt. rubescens, Lw.
(Cryptophasa rubescens, Lw., Ins. N.S. Wales.)
Male 45mm. Head ochreous-white. Palpi white, second joint reddish-tinged above. Antennae ochreous, base white. Thorax reddish-ochreous, anteriorly rosy-tinged. Abdomen and legs ochreous-orange, anterior legs ochreous - reddish. Forewings oblong, posteriorly slightly dilated, costa slightly arched, apex obtuse, hind margin slightly sinuate, hardly oblique, rounded beneath; 2 from ¾; ferruginous, irrorated with elongate light brownish-ochreous scales; costa broadly suffused with pale ochreous from base to beyond middle, attenuated to a point posteriorly; a short obscure dark fuscous dash or [sic] submedian fold at ¼, and another beyond middle; a small roundish ill-defined dark fuscous spot in disc at 5/8, and another at ¾, more elongate: cilia ferruginous. Hindwings with veins 6 and 7 from a point or short-stalked; ochreous-orange, somewhat paler posteriorly; cilia light orange, becoming ferruginous around apex.
Duaringa and Brisbane, Queensland; Newcastle and Sydney, New South Wales; bred not uncommonly in November. Larva residing in a barricaded tunnel in stems of Acacia longifolia, carrying in the phyllodia for food, in August and September.

Fig 73, Cryptophasa rubescens, maxillary palp, Philpott 1927
Good examples of progressive reduction in the maxillary palpi are exhibited in this large family. Lichenaula has a five-segmented palp; the genera Telecrates, Odites, Procometis, Agriophora [sic], Chalarotona, Scieropepla, Eschatura, Uzucha, and Catoryctis have each lost a segment; Xylorycta and Maroga have only three remaining; Cryptophaga rubescens has two, with a third represented by a minute papilla, while in C. nubila this papilla ,has been lost. (Philpott, 1927).
C. rubriginosa is nearly as large as the last [C. irrorata]; the fore wings are reddish brown. There is a salmon tint on the thorax extending on to the base of the fore wings; the hind wings are brownish yellow. The larvae feed in the stems and branches of several species of Acacia. (Froggatt, 1927).
Fig 36.32E: Cryptophasa rubescens Common 1970
C. rubescens Lew. (Fig 36.32E) tunnels in the stems of Acacia, covering the entrance with a web of silk, and feeding on leaves it drags to the tunnel. (Common, 1970).
Cryptophasa rubescens D’Abrera 1974
The genus Cryptophasa contains some beautifully marked species. C. irrorata Lewin and C. rubescens Lewin are two of the commoner species. (D’Abrera, 1974).
Fig 79.5: Cryptophasa rubescens pupa, Common, 1990
The pupae are cylindrical, usually with sclerotised flanges on the abdominal segments, and sometimes, as in C. rubescens, with grotesque sclerotised structures on the head (Eltringham 1919). (Common, 1990).
Pl. 6.2: Cryptophasa rubescens Common 1990
C. rubescens Lew. (Pl. 6.2) has a similar broad distribution, [southern Queensland to Tasmania] but its larva bores in the stems and branches of Acacia (Mimosaceae), feeding on the phyllodes which it attaches at the tunnel entrance. (Common, 1990).
Cryptophasa rubescens is a large, common moth found from Coen, Queensland to Melbourne, Victoria. The larvae bore into many stems of Acacia and cut leaves that they tie with silk to webbing at the entrance to their hole. They then feed on those leaves as they dry out. This is a male. (Zborowski and Edwards, 2007).
