Eucalyptus Long-horned Borer

Phoracantha semipunctata


The Eucalyptus Long-horned Borer is mainly dark reddish brown. There is a yellowish brown area in middle of the elytra, and a yellowish brown patch near the tip. There is a zigzag line bisecting the light area in the middle of the elytra The antennae are very long - about one a half times the total head and body length in male, and slightly longer than body length in female. The antennae of males have prominent spines.


I'm not a 100% sure if it's this Borer. If you can identify it plz let me know :).
