    These were small wrinkled 5 mm wide balls at the end of stems of a casuarina tree. At least one small branch had several of these with holes ( parasitoid ?). Most were dry but a single fresh green gall on the same branch had a knobbly surface. When dissected the gall showed several thick-walled locules. These look similar to galls seen on C.glauca induced by the gall wasp Selitrichodes. I would greatly appreciate help with identifying the gall inducer and the Casuarina species. Thanks.


  • Uromycladium tepperianum

    31 Jan 2017-38.1,145.2Jeff Triplett

    Gall caused by a rust fungus, about 10cm across, on a large Acacia Mearnsii. Update: Uromycladium tepperianum has been split into at least 16 different species each infecting a different range of Acacia species. The one on Acacia mearnsii is called Uromycladium murphyi. See "Diversity of gall-forming rusts (Uromycladium, Pucciniales) on Acacia in Australia" by C. Doungsa-ard et al, Persoonia vol. 40, 2018 pages 221–238.

    1. David Francis  Hi Jeff, great to have you keeping ahead of the game! Split into 16 species - that's a lot! We usually wait until the new names appear in the ALA before updating. The ALA names are sourced from Ausfungi (MEL)

    More bud galls on Black Wattle. I have only seen this sort once. I think they might be caused by Asphondylia glabrigerminis. Species is described in P Kolesik, RJ Adair, G Eick (2010) "Six new species of Asphondylia (Diptera:Cecidomyiidae) damaging flower buds and fruit of Australian Acacia (Mimosaceae", Systematic Entomology 35:250–267. There are some poorly reproduced photos in Adair, R.J., Burgess, T., Serdani, M. and Barber, P. (2009) Fungal associations in Asphondylia (Diptera: Cecidomyiidae) galls from Australia and South Africa: implications for biological control of invasive acacias. Fungal Ecology, 2 (3). pp. 121-134.

  • Trioza spp.

    18 Oct 2015-37.9,145.3Leuba Ridgway

    This eucalyptus tree with slightly pendulous branches and small clusters of creamy white flowers had delicate young leaves with their tips curled into thick cups. These cups appeared to have a membranous pale or brown lid (pic 5). Some of these cups had ants clustering around them as in pic 4. On opening one of these lidded "cups', I found a 3 mm psyllid nymph with small red wide-set eyes, orange thorax and green abdomen. Wings buds were dark with a white substance stuck to them. The tree had several young leaves with these galls. Spotted on a box gum ( ? Eucalyptus microcarpa) in a bushland reserve. I am not sure of the relationship between the ants and this species of psyllid. The gall-forming behaviour seems similar to Trioza species of psyllid. My thanks to Ken Walker for confirming that this is Trioza ( species not known).

  • Eulophidae spp.

    13 Apr 2015-38.1,147.1Suzanne Jones

    Ken Walker states that this is a gall that is wasp induced and this wasp has probably just emerged. He said it is Eulophidae spp. and is possibly Leptocybe invasa.

  • 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.

  • Apiomorpha spp. Apiomorpha urnalis

    14 Apr 2011-37.8,145.3Martin Lagerwey

    Apiomorpha urnalis is a woody gall produced by a parasitic hemipteran. The female inside the large gall remains physically underdeveloped and never independent of her host plant. The dissection shows the larviform adult female.

    1. Chris Lindorff  Hi Martin. Apiomorpha urnalis has now been added. Nice cut-away view of the larva.

    2. Martin Lagerwey  btw, the cut-away is the adult female who never develops any further

  • 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.

    Mountain Hickory Wattle Leaf Gall Several leaves of this young acacia shrub had circular to oval patches of thickened, firm, raised growths with brown encrustation on their pale convex surfaces (pics 1 to 3). The growths were concave on the underside with a outer circle of similar brown crust (pic 4). These patches did not occur in any particular part of the leaf - some involved the mid vein and others anywhere on the leaf lamina. A dissection of one of these structures revealed just thick tough plant tissue. Spotted on young Mountain Hickory Wattle ( Acacia obliquinervia) shrubs on Mt Donna Buang (1250 masl) Architect of gall unknown.


  • Apiomorpha conica

    28 Apr 2014-38.1,147.1Suzanne Jones

    These are male galls of a scale insect, Apiomorpha spp. They are on the leaves of a Eucalyptus globulus. About 40cm away from these hundreds of male galls, was one female gall, on the branch.

    This is a female gall of a Scale Insect - Apiomorpha spp. This gall is on a lower branch of a Eucalyptus globulus. The second photo shows the whole branch, with this female gall at the right of picture, and the male galls on the leaves at the left of picture. Identified by Lyn Cook as Apiomorpha conica.

    These 6 dead insects were hatched from a gall on Eucalyptus melliodora (shown in 3rd photo). Ken Walker has identified them as Torymus spp. of the family Torymidae.


  • Allocasuarina verticillata Drooping Sheoak

    25 May 2012-37.5,144.6Russell Best

    Single old female plant surrounded by many young plants, all female. No male in this copse. The 'fruit' pictured are actually galls, probably Cylindrococcus (Hemiptera).


  • Paropsisterna variicollis

    Photos taken over 2 years. Assumed they are all the same species - all photos taken within a few metres on the same tree - Eucalyptus aromaphloia.


  • Paropsisterna variicollis

    24 Feb 2012-37.4,144.7Russell Best

    I assume these two pics are the same species. They are on the same plant close to each other, and on the same plant/location as obs 2072 last year. On Eucalyptus aromaphloia.

    1. Unknown  Chrysomelidae is the correct name(family=Chrysomelidae) . The second image is an unrelated leaf gall produced by a parasitic wasp or fly.
