Spotted Longicorn (Eburophora octoguttata) -male
An attractive dark brown longicorn with medium-length black antennae and thick femurs. Elytra had small pale yellow spots. The beetle would have been about 18 to 20 mm long.
Spotted on black wattle (Acacia mearnsii) - in a national park.
My thanks to WildFlower and Martin Lagerway for their help with the ID.
Note that this particular specimen is a somewhat aberrant colour form with extra spots as compared to the usual "factory issue" Eburophora octoguttata.
Eburophora octoguttata White, 1855 is a medium sized Longhorn Beetle (Cerambycidae) endemic to south-eastern Australia. It has been reared from various species of Acacia (A. decurrens, A. irrorata and A. melanoxylon).
