This page contains pictures and information about Longicorn Beetles, family Cerambycidae that we found in the Brisbane area, Queensland, Australia.
All members in this family Cerambycidae are commonly called Longicorn Beetles. They are also known as Long-horned Beetles. They are from small to very large in size. They have very long antennae, typically 11 segmented. The antenna is often more than two-thirds, some are even three times as their body length. Their antenna can be directed backwards over body. The compound eyes are notched at the base of the antennae. They have apparently four segments on each tarsus.

Adults are active fliers. The body usually elongated and cylindrical in shape. Their legs are medium long. They have obvious strong mandibles for chewing, some feed on flowers. 
Longicorn Beetles lay eggs  in cracks of barks or under barks. Most Longicorn Beetle larvae are wood borers. Usually they are host specific of living or dead trees, usually infest severely on weakened trees, dying or felled logs. The life cycles are from few months to more than a year. 
Longicorn Larvae are also known as Round-headed Borers. They are  hardly be seen for they live inside wood. They are usually white grub looks with large dark brown head and strong mandibles. They are slightly tapering towards the end. Some species tunnel deep into the heartwood and some bore largely under the bark. They pupate inside the wood as well. When hatch, the adults cut emergence holes through the bark.
In Australia we have four longicorn subfamilies.  Cerambycinae and Lamiinae are common while Prioninae and Parandrinae are rare. We found different species of Longicorn Beetles and listed in the following subfamily pages. As you can see there is quite a bit to learn about the Beetle. If it really interest you might want to switch your study course from a online mba to checking out a park ranger job or even studying up on Botany could help.

Subfamily Cerambycinae

Longicorn Beetles in subfamily Cerambycinae can be distinguished by the head prognathous (with jaws forwards). Most of them have slender body. Some of them are colourful.

Subfamily Lamiinae

Longicorn Beetles in subfamily Lamiinae can be distinguished by the head hypognathous (with jaws down). Most of them have stout body and brown in colours.
