A survey of wood-infesting beetles found in structures in Florida began in January 2004. Pest control industry professionals and county extension agents were asked to send in any specimens of beetles they collected or received. Specimens were identified to species and information on location, item that was infested, and where the item came from was collected. The most commonly received beetles were from the family Bostrichidae of which the majority were from the sub-family Lyctinae. Of these, a significant number were non-endemic, though cosmopolitan, species: Lyctus africanus and Minthea rugicollis. Statistics from the U.S. Department of Commerce indicate that a dramatic increase in the importation of wood products from southeast Asia, especially China, may explain the increase in infestations of exotic beetle species in Florida within the last few years.

I have a black beetle with what looks like to large black eyes rimmed in white on the back of its head. The beetle has some white markings on its back and is approx 1-1/2" long. It has bored holes into areas of the tree where lower, larger limbs have been removed. I tried to send photos but the files are larger than your required 150kb. Can you help me identify and learn how to treat if they are a threat to my tree?
Thank you.

In May 2007, we moved into a new construction home in W. Boynton Beach, which came with several young oak trees, planted at the time of construction. The drought was in progress at the time......we noticed small beetles on the bark, and holes in the tree, oozing sap.....beetles in the sap....now the sap has stopped oozing, but the bark is curled away and the tree is in obvious distress - lost leaves not regrowing...small branches dead, top most of tree is baren..... Palm Beach County has just planted many oaks in the swales at each home in development. Ouyr fear is this may be oak beetles, and they will infest other oaks. What can you do to help? Who should we contact?
