Oechalia schellenbergii is a species of a soldier bug insect native to New Zealand and Australia. It is a predator of insects in native ecosystems and in gardens. They feed on free-living insects such as caterpillars and beetle larvae.
The adult grey-brown bugs have a very variable appearance. They have distinctively pointed thorns on the shoulder of the pronotums. The body length varies from 7.5 to 12 millimetres. The body and forewings have a pale background covered with dark punctures. The tip the scutellum is a pale colour. Each dark brown antenna has three sections. The six legs are a pale brown.
The adults have two pairs of wings. The front pair is modified as covers for the hind wings. Part of the forewing is coloured brown, while the rest is membranous.

Adults overwinter in sheltered places and appear in November to lay clusters of >28 black eggs in rows. Each egg has a prominent ring of white spines on top. There is one generation per year. The hatched nymphs go through five nymphal instars (stages) by moulting. The first instar nymph is the only stage that is not a predator.
