[Thread] So, here's a problem that may already have a solution...! Apparently, #ElmZigZagSawfly, an invasive species, is spreading in the #Northeastern US and can defoliate #ElmTrees (which have been making a comeback from #DutchElmDisease), and has adapted to switch tree species. However, #AsianLadyBeetles, another invasive species and the natural predator of #LanternFlies (and aphids and other pests), is also spreading! I know we always have some Lady Beetles inside our house, and instead of killing them, my plan is to catch and release them outside... So they can hopefully do their thing! (And yes, we have quite a few Elm trees, descendant of a survivor tree that fell down recently, in our tree stand).
Elm Zig Zag Sawfly
"The first confirmed detection of the elm zigzag sawfly in North America occurred in August 2020 in Québec, Canada (Martel et al. 2021; https://www.invasivespeciescentre.ca/first-confirmed-sighting-of-a-new-invasive-in-north-america-elm-zigzag-sawfly/). Canadian authorities were unable to determine the introductory pathway or amount of time the insect had been present [Invasive Species Centre].
The Canadian population was not the only outbreak on the continent, however. Earlier the same year, the tell-tale feeding pattern – zigzags on the tree’s leaves — was observed in Frederick County, Virginia (northwestern corner of the state). Since no specimens were recovered, identification was not confirmed. A year later, specimens collected from the same confirmed the presence of EZS [David Gianino, State Plant Regulatory Official (SPRO) of Virginia, pers. comm.]. Additional surveys that summer led to detections in eight additional Virginia counties [K. Oten blog].
Also in the summer of 2021, symptoms were observed in Lehigh County, Pennsylvania. Again, however, the absence of a specimen prevented formal identification [K. Oten blog]. In 2022, official detections were made in Pennsylvania, North Carolina, Maryland, and New York [NCSU extension]. The New York infestation might have spread naturally across the St. Lawrence River from the Canadian population [https://www.wwnytv.com/2022/10/03/new-pest-affecting-elm-trees-st-lawrence-county/].
In 2023, outbreaks were detected in Ohio, Vermont, and Massachusetts [NCSU extension map]. In 2024, Wisconsin found EZS in several counties [University of Wisconsin extension]. Neither the Canadian Food Inspection Agency nor the [Canadian] Invasive Species Centre reports on EZS’ more recent status in Canada."
[...]
"Since most trees can recover from sporadic or minor defoliation events, the state extension programs say control efforts are often not warranted. Furthermore, since EZS is a new pest species, little is known about effective management. Results of experimental treatments using various pesticides or biopesticides are reported from Hungary (Blank et al. 2010), Romania (Fătu et al. 2020), and Virginia [NCSU extension]. The University of Wisconsin and University of Massachusetts extension service mention several predators present in Europe. The University of Massachusetts extension service notes that the multicolored Asian lady beetle, Harmonia axyridis, which preys on EZS in Serbia, is also present in Massachusetts (actually, it is widespread in the United States); its impact on elm zigzag sawfly in Massachusetts is uncertain."

On the east coast last week, swarms of invasive lantern flies were so massive that they were visible on radar.

Lanternflies, considered invasive and destructive of crops, are swarming along the U.S. East Coast. At Cape May, NJ this week, we discovered that Atlantic ghost crabs feast on #lanternflies, and we have the pictures to prove it.

Ants could be a secret weapon in fight against invasive lanternflies https://www.futurity.org/ants-spotted-lanternflies-3287432/
Ants that ate just one meal of honeydew from spotted lanternfly still carried the pest’s DNA up to five days later, and because ants roam widely, they detected lanternfly presence up to 100 meters, or 328 feet, away from known infestation spots.

This captivating macro photograph showcases two brilliantly coloured lanternflies, their bodies adorned with a symphony of vibrant greens, oranges, and yellows. Perched on the textured bark of a tree, these insects seem to glow against the dark background.

"In 2003, Anne Nielsen became the first doctoral student in the U.S. to study the brown marmorated #StinkBug, which was beginning its ascendancy as an #InvasiveSpecies... Now an associate professor, Nielsen is also a specialist in tree fruit, with a focus on invasive species like #StinkBugs and spotted #lanternflies. Her goal is to protect the natural world by developing sustainable management practices."

Just saw a lanternfly climbing on a pigeon, might go throw up now.

I hope #lanternflies are non-toxic, because Rocketboy just caught and ate one.

Have you heard about this wonderful 9-year-old citizen #scientist who serviced the world by not only stomping out invasive, dangerous #lanternflies but also collecting samples for research?
~ Neighbors called the cops on her ~
...complaining of a "little Black woman, walking and spraying stuff on the sidewalks and trees”
Well, happy ending-- Bobbi was later recognized by Yale for her efforts (see image below) 🎉
Of the incident, her mother said, "“I wanted it to be a teachable moment. This same call could’ve happened in another state with another police officer, and I would be grieving.”
