Ecology: Instream habitat: Ochteridae species are semi-aquatic bugs that occur in the littoral areas of quiet waters, especially mudflats and sandbars, in association with riparian vegetation. Ochterid bugs are particularly vulnerable to habitat disturbance. Feeding ecology: Ochterid bugs are predators, feeding mostly on fly larvae (Diptera), springtails (Collembola) and aphids. Habit: Commonly known as ‘velvet shore bugs’, they are cryptically coloured, run quickly over sunlit open ground and jump or fly short distances. The nymphs of some species are slow moving and so camouflage themselves by scooping sand onto their dorsum using a small comb on the anterior portion of the head, just over the labrum, and positioning it using the fore- and hindlegs. Life history: The biology of Megochterus species is unknown. Ochterus eggs are suboval in cross-section. The female lays her eggs singly amongst debris and on sand grains. At the last moult, Ochterus nymphs build small cells of sand in which they stay for two days before and after moulting. |
