  • Lachnodius spp. Lobe-margin Felt Scale Insect

    17 Oct 2015-37.9,145.3Leuba Ridgway

    This female adult felt scale looked like a 5 mm long and wide, slightly raised peach-coloured patch on a leaf. The leaf surface surrounding it was damaged. faint body segments could be seen on the upper surface which had wispy white waxy secretions. The underside (pic 1) showed three pairs of legs, a slight depression between the first pair of legs ( ? mouth) and well defined abdominal segments. A pair of antennae were visible when the scale was turned over. Spotted on a eucalyptus tree in a reserve. Several leaves were affected by these scale but there was no more than one per leaf. My thanks to Dr Lyn Cook who identified this as Lobimago sp. , a Lobe-margin Felt Scale. Family: Eriococcidae Dr Cook writes " Was in genus Lachnodius but transferred to Lobimago by Hardy et al in 2011." . At present on ALA as Lachnodius.

      • Leuba Ridgway  Thank you David. I agree it is weird, especially the flesh colouring and the concept of having a mouth in its chest !!

  • Monophlebulus spp.

    28 Oct 2015-37.9,145.3Mark Ridgway

    Large scale (24mm) often called 'Snowball Giant Mealybug' This one has matured to the point where the covering of 'snow' (white fluff) is gone. It was found on the trunk of a large, broad leafed acacia and very close to a huge ladybird larva (yet to be identified - previous sighting) Possibly predator and prey. Possibly M pilosior. http://bie.ala.org.au/species/Monophlebulus+pilosior

  • Tanyscelis maculata

    27 Feb 2015-37.9,145.3Leuba Ridgway

    These are scale insect galls seen on the adaxial side of the leaf . The broad-based conical outgrowths are female galls. There were two of these, one at the base of the leaf base and another along the main vein. the gall was purplish and had a ring near the base. One of the galls showed two openings and the other a single smooth circular orifice. Also on the leaf surface were many upright tubular structures with apical openings with crenulated margins. These were male galls and they were tinged red. Spotted on a eucalyptus tree - ? species. Nature reserve. My thanks to Dr L.Cook for confirming genus and identifying the species.

    1. Chris Lindorff  Hi Leuba. I've added this species name to the database and included Opisthoscelis maculata as a synonym. The ALA is yet to pick up on this new genus (published in 2010). Thanks. Chris.

  • Opisthoscelis beardsleyi

    26 Sep 2014-37.9,145.2Leuba Ridgway

    These sub-conical galls with apical holes are female galls of a gall inducing scale insect. The female galls showed enlarged leaf glands. Some leaves also showed small cylindrical galls with apical openings- these were the males of the same species of scale insect (pic 3). Pic 2 shows galls of both sexes on the one leaf. The underside of the leaf showed slight discolouration and minimal waxy bloom (pic 4). Spotted on juvenile leaves of a eucalyptus tree (species unknown) in a nature reserve.

  • Eremococcus turbinata

    09 Apr 2013-38.0,145.4Leuba Ridgway

    A lobulated gall probably involving terminal leaf buds. the galls were green and red and glossy. they were small, about 5 to 7mm wide. A dissected dry gall ( pics 4 & 5) showed thickened concentric layers of tissue. There was no sign of any life inside the gall. Spotted on a prickly tea-tree (Leptospermum juniperinum). This gall is formed by a scale insect of the genus Eremococcus. My thanks to L.Cook for the ID.

  • Eriococcidae spp. Eriococcid Scale Apiomorpha spp.

    18 Feb 2011Martin Lagerwey

    This gall forming scale bug (Apiomorpha munita, family = Eriococcidae) produces a chemical stimulant causing the plant to grow a protective cage. The smaller posterior structures are (empty) male galls. The dissection shows the adult female prisoner with reduced wings, legs, antennae etc.

    1. Mark Ridgway  Apiomorpha munita ?

      Reply • 05 Mar 2015

      • Martin Lagerwey  Mark, that is bound to be right. I used the name eriococcidae which is the family name years ago before I understood what I was talking about. You are welcome to add the correct name. Here is a link to Lynn Cook whom I am certain that you know of, and her slideshow of 40 images of the species in this genus which you might not have found yet ... a great insight into her work. http://www.lyncook.org/Lyn_Cook/Apiomorpha.html

        • Mark Ridgway  Yes I wish her book was as comprehensive as her website.

    2. Martin Lagerwey  Thanks Mark, I've corrected that. There's too many words in our language. Hey, you calling me old? :)
