Q. Has the Asian Longhorned Beetle (ALB) been eradicated?
A. No, it has not been fully eradicated. One of NYC’s most common street trees, the Norway maple, is also one of ALB’s preferred species for growing and laying its eggs. For a list of ALB host species, visit the U.S. Forest Service Northeastern area website. NYC Parks Department has a list of both approved and prohibited tree species to use as street trees.
Q. What does the Asian Longhorned Beetle look like?
A. The Asian Longhorned Beetle (ALB) is large, 0.75-1.25 inches long, with long black and white antennae, and a black body with white spots. Adult beetles emerge from host trees as early as June, creating round exit holes approx. 3/8” in diameter. Heavily infested trees may be accompanied by frass (sawdust) and sap oozing from the holes.
