Earth Calendar for August 16th and August 17th

Aug 16, 2013



The U.S. Department of Agriculture has designated August as Tree Check Month and urges the public to check trees for signs of Asian Longhorned Beetle (ALB).    

August is a time of peak emergence for the beetle and is most likely when members of the public will see an adult beetle infesting trees. The USDA is asking people to take 10 minutes and check their trees for the beetle and any signs of damage it causes.  Checking trees on your property or in your neighborhood means looking at the host trees the beetle attacks, for the beetle itself or signs of damage caused by the ALB.  The most concerning signs are dime-sized exit holes, roughly ¼ inch or larger, perfectly round, found on the trunk and branches. You can look for round or oval shallow scars in the bark. Dead branches or canopy dieback can also indicate something is wrong.Finally, look for the beetle itself on the tree trunk, branches, on the ground, and on nearby surfaces. The Asian Longhorned Beetle’s unique characteristics makes them easy to identify.   


 • Body is 1 to 1 ½ inches in length• Long antennae banded in black and white (longer than the insect’s body)• Shiny, jet black body with random white spots• Six legs The most important thing you can do to protect your trees is to check them regularly and encourage others to do so too. Early detection is crucial in the fight against this invasive pest. Unfortunately, once ALB infests a tree, there is no cure for that tree.  If you find a beetle, try to take a picture or capture it by placing the insect in a jar and freezing it. This will help with identification. To report a sighting or for more information, visit the website  or call the toll free hotline at 1-866-702-9938.
