Several specimens of the Valley Elderberry Longhorn BeetleOn the left there are three different specimens of the Valley Elderberry Longhorn Beetle. They were collected by Dennis Haines of the California Agricultural Department, Tulare County. Dennis says the skinny one in the middle is the one that was found in Three Rivers and is the one that is suspected to be living at Kaweah Oaks Preserve.

We've found evidence of VELB at KOP!!

Valley Elderberyy Longhorn Beetle exit hole
In late October 2001 we began a search for the Valley Elderberry Longhorn Beetle (VELB). Since we have documented the presence of this threatened species on KOP, Caltrans has promised the funds to acquire the old plum orchard for the sole purpose of mitigating elderberry habitat that will encourage the reproduction of this species.

We have successfully documented VELB exit holes in three areas of the Preserve. However, Dennis Haines, of the Tulare County Ag Commissioner's Office, advises all but one exit hole found were in old wood and not acceptable. One find is not substantial and he recommends we continue the search. 

We still need to search the following areas: click to view a map of previously searched areas
