Original description, Lewin 1805
Pl. 14: Lewin, 1805, pre-publication print, State Library of NSW
Cryptophasa Strigata. Pl. 14.
Noctua Cryptophasa with light wainscot coloured wings; anterior with a brown stripe from the shoulder to the end. Posterior wings with a broad silvery fringe: the whole insect silvery, especially near the stripe.
The larva of this little Noctua is provident, and wood-boring: our specimen had entered a sappy branch or slender stem a the Banksia Serrata, where it had formed a cell, having its entrance barricaded with a fabric of interwoven web and excrement; under which the larva conveys its food, by nightly perambulations, that is, so much of a leaf of the above tree as it can conveniently carry away at a time, and which it forces part down its cell, where, in security, it feeds and sleeps during the whole day. Within this dwelling it transforms to a pupa, generally in January; remains twenty-two days in that state, and is on the wing in February, and then found on Banksia shrubs near Sidney. The male is figured at 3; the female at 4; the pupa, with the wood laid open at 2; the larva at 1; and the barricado at 5.
Subsequent description, Boisduval 1832
C. RAYÉE, Strigata.
Alis pallide cinereis; anticis vitta longitudinali nigro-fusca.
Ailes d'un gris-cendré pâle; les supérieures avec une bandelette étroite longitudinale prolongée de la base à l'extrémité et d'un noir brun.
Lewin, Prodr. Ent., pl. 14, p. 15.
Elle est de la taille de Lithosia Complana, et elle a tout-à-fait le port et le dessin de plusieurs de nos Tinèides d'Europe. Son corps est beaucoup plus mince que dans les espèces précédentes, et les antennes du mâle sont à peine pectinées.

Subsequent description, Meyrick 1890
Xyl. strigata, Lw.
(Cryptophasa strigata, Lw., Ins. N.S. Wales.)
Both sexes 22-32 mm. Head and thorax light fuscous, patagia sometimes whitish towards base. Palpi and antennae fuscous-whitish. Abdomen whitish, anal tuft whitish-ochreous. Legs whitish, anterior pair fuscous. Forewings elongate-oblong, costa gently arched, apex round pointed, hindmargin nearly straight, oblique; white; dorsal half light fuscous; a moderate straight darker fuscous streak above middle from base to apex: cilia white, round anal angle light fuscous, sometimes with a light fuscous subapical line. Hindwings whitish-fuscous, more whitish towards base, more or less suffused with darker fuscous towards apex; cilia whitish.
Sydney, New South Wales; Melbourne, Victoria; in November and December, common. Larva 16-legged, stout, cylindrical, with scattered long whitish hairs; whitish, posteriorly suffused with pale pinkish-ochreous; segments 5-12, with a square of four transverse-elongate black spots on back, a large irregular black spot on side, enclosing a pale ocellus, a small black spot beneath this, and two others behind it, and an irregular square of four round black spots below these, whole surface, except spots, broadly reticulated with pale carmine; fourth segment with a large double-triangular spot on back, third with a much larger one, each with four or five irregular spots on sides; second segment deep amber, each side with narrow black transverse stripe; head rugose, black; anal segment pale yellowish, shining. Feeds on Banksia serrata and other species of the genus, and on Lambertia formosa, residing in a barricaded tunnel in the branches, and carrying in leaves for food, in August and September.

Banksia is the food plant of several other tunneling species including Xylorycta strigata (Lew.) (105, male 1.2 inches). (Common, 1963).

X. strigata (Lew.) is white with a broad fuscous longitudinal stripe on the fore wing. (Common, 1970).
The larva tunnels in the branches of Banksia serrata and B. integrifolia, and of Lambertia formosa, feeding on leaves which it drags to the entrance of the tunnel. (Common, 1970).

Fig. 23.9: Common, 1990

One of the commonest species is X. strigata (Lew.) (Fig. 23.9). It ranges from Yeppoon, Queensland, to south-eastern South Australia. The larvae live in a tunnel they excavate in a stem or branch of Banksia (Protaceae), covering thee entrance with a web of silk and faecal pellets and emerging at night to cut off leaves which are attached at the entrance to the tunnel to be eaten later. It has also been reported from Lambertia formosa (Protaceae). (Common, 1990).
