On August 5, the Washington Department of Fish and Wildlife (WDFW) received notification from a local wholesale aquarium company in Renton of possible invasive freshwater mussels on a shipment of Marimo moss balls (Aegagropila linnaei). Moss balls are a commonly used decorative algae in aquariums and water gardens. Lab testing confirmed the mussels were zebra mussels (Dreisena polymorpha), a prohibited aquatic invasive species in Washington that, if established in local waters, would be capable of causing significant infrastructure and environmental damage. Zebra mussels and a close relative, the quagga mussel, are not known to be established in Washington.

Washington State Department of Agriculture (WSDA) detected two Japanese beetles near Grandview and one near Sunnyside in 2021. Additionally, a resident reported numerous Japanese beetles devouring her roses in Grandview that summer.

Japanese beetles would pose a serious threat to farms, gardens, and the environment if they were to become established in Washington State. Please report any suspected sightings of Japanese beetle at PestProgram@agr.wa.gov or 1-800-443-6684. See WSDA's Interactive Japanese Beetle Response Map.

Maine Forest Service. Winter moth was first recorded in Nova Scotia in the 1930s and then in the Pacific Northwest in the 1970's. It showed up in eastern Massachusetts in the early 2000's and has since spread into coastal Maine from Kittery to Bar Harbor. Fill out the Tree Ailment Form to help us gather information about the distribution of these moths across Maine (or use survey for any tree health or forest pest issues you're observing). 

In early December Washington Department of Fish and Wildlife (WDFW) Police received information that a Seattle market was selling live “green crabs”.

The Midwest Invasive Species Information Network (MISIN) is a regional data aggregation effort to develop and provide an early detection and rapid response (EDRR) resource for invasive species in the Midwest region of the United States.

Forest pest first detectors are trained to quickly detect and diagnose early infestations of emerald ash borer, spongy moth, Asian longhorned beetle, Japanese barberry, Oriental bittersweet and other pests, so that state and federal agencies can control the spread. Become part of the award-winning Minnesota Forest Pest First Detector volunteer program to help the public find new invasive species affecting Minnesota’s trees and forests, or attend as a refresher for those already active as Forest Pest First Detectors.

MISIN Learn is part of the Midwest Invasive Species Information Network (MISIN), which provides online courses of varying complexity targeting species identification; data collection and reporting; Their goal is to assist both experts and citizen scientists in the detection and identification of invasive species.

Are you a crabber, waterman, or concerned citizen? We need your help to detect and assess the status of Chinese Mitten Crabs. The "Mitten Crab Watch" website provides information on the invasion of the mitten crab and allows users to more easily report catches.

Please help us detect live mitten crabs by reporting any sighting in North America. We are especially interested in collecting sightings from the Chesapeake Bay, Delaware Bay, Hudson River, and San Francisco Bay --- where the crab has been common in the past. Please visit the Mitten Crab Watch website to learn more about the crab and to report sightings.
