The adult silky hairstreak has a wingspan of 28mm.[4] The male and female are similar, with the wings of the female slightly more rounded.[1] The wings are black or brown on top with yellow-orange patches. The lower wings have orange patches and black tails with white edges. The underside of the wings is yellow-grey in colour with black and orange markings. The eggs are pale green with a diameter about 1mm.[1] They are usually laid in small groups on the twigs of a food plant.[1]
The caterpillars grow to a length of around 3 cm. They have a black head and a brown, red, black and yellow body.[1] The larvae of the silky hairstreak secrete substances that attract Anonychomyrma biconvexa ants.[5][6]
Distribution and habitat
It is found in South Eastern Australia including New South Wales, Victoria and Tasmania.[7] The species only occurs where the attendant ant species is found, and the larval food plant grows.[8]
The caterpillars feed on various Acacia species including the Acacia dealbata, Acacia decurrens, Acacia elata, Acacia mearnsii, Acacia melanoxylon, Acacia obtusata, Acacia pravissima, Acacia terminalis and the Acacia trachyphloia.[1]
