There are plenty of dying cyprus. Samples of bark and grubs have been sent to DEPI for identification. This may take maybe several months. (February2014?)
Meanwhile if anybody sees beetles on the trees contact Rod or Shari at Lismore Landcare, or "contact us" at the top of this page.
Many healthy cyprus have some grub tracks under the bark but healthy branches seem to "drown" them with sap. For some reason this has stopped happening.
Cyprus dying in Williams St, Lismore
This is a grub from under the bark. There are similar grubs in most branches.
Grub. Click here for a Link to an article about a similar grub.

Above: Flat headed borer (jewel beetle?) grub tracks in a "healthy" branch.
They may be a species of jewel beetle. The female of some jewel beetles do not fly. This may be why trees die in patches.
Above: Cyprus trees are dying throughout the district. These are near Derri P12 college.
Cause is not certain. Suspects are:
1. cyprus canker (Seridium)
2. Possibly also cyprus bark beetle (Phloeosinus sp.)

Above: more of the cyprus bark beetle (?) on Deep Lake Rd. These are different to the jewel beetle in the Lismore photos.

This may be cyprus canker which entered through the grub holes.
