The Asian Longhorned Beetle (ALB) was found in Worcester, MA in August 2008 and in Boston in July 2010. This insect pest poses a serious risk to trees and forests. ALB has not yet been found in New Hampshire. Help us by looking at the debris from your swimming pools. Whenever you clean your pool, look at the debris you collect in your filter and skimmers. Use this fact sheet (PDF | 1.22 MB) to compare collected insects to common insects. Upload pictures of any insect you think is a longhorned beetle.

The spotted lanternfly – a destructive, invasive plant hopper – has been confirmed in New Castle County. Delaware is the second state to have found the insect which was first detected in the United States in 2014, in Berks County, PA. The spotted lanternfly has now spread to 13 Pennsylvania counties.This insect is a potential threat to several important agricultural crops including grapes, apples, peaches, and lumber. State plant health and forestry officials are providing information, fact sheets, photographs, and links to other resources at Delaware's Spotted Lanternfly resource page. Early detection is vital for the protection of Delaware businesses and agriculture.

As of February 2015, brown marmorated stinkbug (BMSB) has been confirmed in 20 New Hampshire towns/cities. With the exception of a confirmation on nursery stock (shipped several months earlier from Long Island, NY), no specimens have yet been found on any crop. The vast majority of specimens have been found on or in buildings. We need your help. We want to find out where BMSB occurs in New Hampshire. Let us know if you see this species in or on your New Hampshire home. Verbal descriptions are not much use, but clear, close-up photos or specimens are helpful. We want to track this insect in NH and how it builds in numbers.
