. The Australian zoologist. Zoology; Zoology; Zoology. 306 LEAF-MINERS Mines occur on M. integrifolia during spring and autumn at Sydney. They may be up to 60 mm. in length, with the blotch portion always across and along the centre vein of a leaf. The blotch area has markings of a rusty red- brown colour caused by the lines of excreta within the mine. Last instar larvae deepen the mine, and affected leaves bear patches of brown where tissues have died beyond the mine. Acrocercops hoplocala Meyrick. Mine type: Linear-blotch (Figure 2). Host: Eucalyptus saligna Smith. Localities: Sydney; Gosfor

Host: Eucalyptus saligna Smith. Localities: Sydney; Gosford-Wyong area, Notes: Larvae have been collected during March, May to September, and November to January. Oviposition always occurs on the upper leaf surface, and the egg is visible as a silvery spot at the commencement of the linear portion of the mine, or on the blotch portion when it has obliterated the commencement of the linear portion. The larva mines directly into the leaf tissues through the base of the egg attached to the cuticle. The upper epidermis is destroyed during early instars when the linear portion of the mine is constructed. Both the linear and the blotch portions are white, but pale brown staining from the excreta of the early sap-feeding instar larva is sometimes evident. Larvae are similar in appearance to those of A. laciniella, with typical prognathous. Figure 2.
