The longhorn beetles in the family Cerambycidae are fairly large slender insects, named after their, sometimes excessively, long antennae.  Many are up to 2cm or more in length, so are readily noticed even casually.  The larvae live in burrows in wood, and can be damaging to growing or stored timber and taking up to 3 years to mature.

They are active fliers, particularly at dusk, but most commonly are seen on their host trees or nectaring on flowers.  The females lay eggs on or in trees where the larvae develop, gnawing passages with their powerful mandibles. The larvae develop inside the tree for up to 3 years, with the adult beetle gnawing its way out through an oval emergence hole.
