The Brown lace lerp, Cardiaspina fiscella, was collected from Eucalyptus botryoides close to Auckland airport on 14.5.96 and later in Papatoetoe in south Auckland. In Australia it has been recorded on Eucalyptus botryoides, E.robusta, E.saligna, E.grandis, E.tereticomis and E.blakelyi and has been classed as a serious pest of E.grandis in south-east Queensland. Adults of this Australian psyllid species are 3.4 mm in length, from head to wing tip. They possess a short robust body with head at right angles to plane of body. Antennae are about equal to width of the head. Legs are stout with 2 very small claws. General colour is light brown; head straw coloured; thorax with several medium brown patches; abdomen brownish black, with yellow or red caudal margin on each segment; forewings transparent; veins uniformly light brown. The nymphs produce attractive lattice-like, shell shaped lerps, found on the underside of leaves. Dimensions c. 4.1 mm from hinge to apex, c. 5.4 mm across. General colour is light brown, darker near hinge with a darker band where the ribs begin to fan out; and is moderately convex. Nymphs can move freely underneath the lerp and can sometimes be seen moving on the undersides of leaves outside of the lerp.
