This species is commonly encountered and easy to identify. The inflorescence appear raceme-like (hence the name), as floral spikelets are spaced along the flowering stem. The floret has an obvious naked patch on the lemma body, with hairs only on the margins. The lemma lobes are long, tapering abruptly to produce filiform points.
Some key features worth remembering for this species, include the often widely spreading lobes of the lemma (especially when mature), the rather even length of hairs over the lemma body that are not in obvious transverse lines, the sub-equal length of the lemma awn to the lemma lobes (often much longer in other species), and the geniculate (bent) flowering stem at a node near the base (see 3rd photo). The leaves are fine, hairy and tightly in-rolled.
Small (7mm long) leaf beetle on Acacia pycnantha. Very shiny all over and difficult to avoid flash-back when photographing with flash. The eyes are brown, but significant eye-shine resulted when photographing.
Very often we find eucalyptus leaves that have been delaminated and puffed into a 'pillow' with a large internal void. This tiny wasp might be part of the story. It was at a rough opening on this puffed leaf and seems to be extricating itself from a skin just inside the hole. About 6mm long with distinctive black pterostigma and a longish flexed abdomen.. It turns out that this is a type of sawfly. Black over the thorax should be Phylacteophaga froggatti (male)
This beefly had a wingspan of about 15 mm. The basal part of the wings were black and this ended in a smooth wavy line. The rest of the wings were clear. Head, thorax and abdomen were black. The abdomen had a soft velvety look and was truncated with the rear end covered with pale setae.
Spotted in a suburban garden.
