The Maryland Department of Agriculture has confirmed that a single adult spotted lanternfly has been found on a trap in the northeast corner of Cecil County near the border of Pennsylvania and Delaware. This is the first confirmed sighting of the invasive species in Maryland, and the department does not believe there is an established population of the pest in the state. If you suspect you have found a spotted lantern fly egg mass, nymph, or adult, snap a picture of it, collect it, put it in a plastic bag, freeze it, and report it to the Maryland Department of Agriculture at DontBug.MD@maryland.gov.

Multiple federal, state and local agencies have been notified of an invasive algae species discovered in Newport Bay, California. The algae, which is native to Florida and other subtropical and tropical locales, is scientifically known as Caulerpa prolifera. It can grow quickly, choking out native seaweeds and potentially harming marine life through lost habitat.
A similar species of invasive algae, Caulerpa taxifolia, was identified in California in 2000 and was successfully eradicated through a comprehensive joint local, state and federal effort in 2006. Due to the similarity between these two species, scientists believe this algae species may pose a serious threat to our local coastal ecosystems.
However, it is imperative that the public avoid contact with the plant due to its extreme ease of recolonizing from just tiny fragments. If you believe you have seen this invasive algae, please complete a Suspect Invasive Species Sighting Report: Invasive Algae - Caulerpa prolifera. Please do not collect a specimen, as this may lead to further spread.

Asian giant hornet is the world's largest species of hornet. In December 2019, WSDA received and verified four reports of Asian giant hornet near Blaine and Bellingham. These are the first-ever sighting in the U.S. Canada had also discovered Asian giant hornet in two locations in British Columbia in the fall of 2019. If it becomes established, this hornet will have serious negative impacts on the environment, economy, and public health of Washington State. If you think you may have spotted an Asian giant hornet, report it to WSDA's Pest Program and, if possible, include a photo.
