    The main picture shows a dissected gall exposing larvae at various stages of development with pale pink segmented bodies and a few eggs (pic 4). The galls were about 3 to 4 mm wide, shiny and green with knobbly tips. They seemed to arise from tips of leaflets (pinnules) and involved most of the leaflet (pic 2). Several of these galls were seen on the pinnae. Pic 4 shows a developing gall on a leaflet. The larvae seemed to have segments differentiated into thoracic and abdominal segments and there appeared to be three pairs of legs (pic 6) suggesting that these were mature and close to pupation ?. I assume these are midge galls and would greatly appreciate confirmation. - ? Austroacacidiplosis botrycephalae Spotted on Black Wattle (Acacia mearnsii) in a nature reserve ( Glenfern Valley Bushland Reserve)

    Looking very much like small Camellia flower buds, these pea-sized growths could easily be mistaken for flower buds on the tea tree. They were globose, had scaly bract like outer growth and layers of soft sheaths within. They did not appear to have stalks and were seen on branches between nodes. On cutting one of them open, I found at least two very small maggots at the base, not much over 1 mm in length. The inside of the gall was soft with white fibrous layers. Spotted on Coastal Tea Tree ( Leptospermum laevigatum)
