Position of the mines on a leaf is vanable, but usually close to the mid-vein of the leaf. The early part of the mine is reddish-brown with the linear portion light brown, the blotch area being darker brown.

Locality: Lisarow; Olney East State Forest, Notes: The pale to bright green larvae have been collected during July, August, January and March. Oviposition occurs on the upper leaf surface, and the larvae leave the mine on the lower leaf surface to spin small dark brown cocoons on the base of the jar. The pupal exuviae is protruded from the case at emergence of the adult. Mines usually occur on mature leaves of E. acmenioides, and on semi- mature leaves of E. saligna, and their position on the leaf is variable. The serpentine portion of the mine is seen as a thin grey line, with the digitate portion darker in colour. The distal portion is greyish-green, and the digitate part appears to be constructed solely in the spongy parenchyma. Excreta are seen as a black central line in the serpentine portion, and the edges of the excreta appear to follow the contours of the digitate portion. Up to 4 chalcidoid specimens of parasites have emerged from one Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Royal Zoological Society of New South Wales; Royal Zoological Society of New South Wales.
