Longhorn Beetle

Longhorn Beetle

Dear Mike,
Though it resembles an Ant, this is actually a Longhorn Beetle in the family Cerambycidae.  Several years ago we posted an image of a mating pair that were identified as being in the genus
Zorion.  there are many nice images on the GrahamNZ website and there is also a nice image on FlickR

Thank you for the information.  I phoned someone who should have known and was told by him it was a flower bug
At least I know its basically harmless.  It will now go in the files with the spiney spiders found last year

Hi again Mike,
In defense of your source, we do have a comment on our previous posting indicating this is a Flower Longhorn, however our research, including a scholarly article on the Massey University of New Zealand site, has determined that it is in the subfamily Cerambycinae, not Lepturinae whose members are commonly called Flower Longhorns according to BugGuide.

    Hi. Just found a few of these longhorn beetles on my avocado tree. Do they eat their flowers as it looks quite decimated atm. What do 8 do to deter them?
