Stenolemus fraterculus is a small (8–10 mm) native predacious insect that eats small insects and is self-introduced from Australia. It is sometimes mistaken for a small mantid (praying mantis).
Although scarcely seen by most people this species is surprisingly common in the city and comes into the house at night on occasions though usually lives outdoors on dead twigs and vegetation. It is very cryptic in colouration and behaviour.
