There are lots of these in the house I've just moved into in the centre of Kyneton. I haven't seen any frass around the place to suggest that their larvae are eating the house, but they just keep appearing! About 5mm in length. Excuse the poor mobile phone image.
We do not know what this plant is. Tightly clumped circle 40cm in diameter, 10cm high, of shiny green elongated leaves 4-7cm long. Mass of leaves with lots of flowers hidden under the leaves. Flowers are hooded, cup-like 3-4cm long with a thick white column inside. White base with purple hood. Plant appears to be connected with roots, not bulbs.
