![]() Destroying an egg mass is another way to help control and reduce the spotted lanternfly population, according to the Department of Agriculture. If someone sees a spotted lanternfly in Erie County or elsewhere, they should kill it, Acevedo said. ![]() Adults, which are about an inch long, can fly but often jump or glide, according to Penn State Extension. When the wings are open, the vibrant red hind wings with black spots are visible. When closed, the wings appear grayish with black spots and black or gray tips that might look striped. Here's what you need to know.Īdults are out from July to November. Both nymphs are strong jumpers.įrom June: Spotted lanternflies are hatching again. ![]() Late stage nymphs are more than half an inch long and are bright red with black stripes and white spots. Early stage nymphs are about 1/4 of an inch long and are black with white spots. Sixteen counties had at least one vineyard that reported an adult spotted lanternfly but those counties were primarily in the southern and/or eastern parts of Pennsylvania, according to a map with the brief. None of the 42 were in Erie County, according to the brief. 23, the Penn State Extension published a brief online titled " 2022 Adult Spotted Lanternfly Status in PA Vineyards." According to the brief, 42 of 55 Pennsylvania vineyards reported adult spotted lanternflies in their vineyards. Grants awarded: These PA state-funded projects could change your outdoor recreation plans from Erie to Lancaster Like Erie, neither Crawford nor Warren counties were among the list of 45 with a spotted lanternfly infestation, according to the map on the Cornell site. Where is it?Īcevedo said there have been reports of spotted lanternflies in Erie County but they were dead and possibly arrived here in cargo rather than being part of an established bug population. One positive, Acevedo said, is that spotted lanternflies don't sting or similarly hurt humans. The waste builds up and can lead to the growth of sooty mold and black-colored fungi, according to the Agriculture Department. "A 2019 economic impact study estimates that, uncontrolled, this insect could cost the state $324 million annually and more than 2,800 jobs," according to the Pennsylvania Department of Agriculture's website.Īlso, a spotted lanternfly excretes honeydew, a sugary waste that attracts bees, wasps and insects. Once established, the spotted lanternfly feeds on sap and has a preference for grapevines, maples, black walnut, birch and willow, which are all important to Pennsylvania's economy, according to the state Department of Agriculture.įrom 2015: Invasive insect could be bad for Pennsylvania's grapes, hardwoods Eradication efforts include physical trapping of the insect in all life stages, removal of tree-of-heaven and continued monitoring by the West Virginia Department of Agriculture and citizens for new populations and egg masses.She added that spotted lanternflies have not only hurt grapevines in southeastern Pennsylvania, but have also killed some. The key to controlling the spread of this invasive pest throughout West Virginia will be early detection and prompt eradication efforts. Sooty mold blocks sunlight and inhibits photosynthesis a vital process for orchard trees and vineyard vines to produce fruit.Īs seen in Pennsylvania over the past several years, spotted lanternfly can spread rapidly when introduced to new areas, especially if major highways, railways or rivers are in proximity of the introduction site. Spotted lanternfly damages the plant host in two ways, 1) by sucking out the sap and weakening the plant and 2) by creating “honeydew” which increases the occurrence of sooty mold. All of these hosts play an important role in the economy and ecology of West Virginia. Hosts include a wide range of fruit, ornamental and forest trees and vines, including: grape, apple, plum, cherry, peach, nectarine, maple and walnut. Tree-of-heaven foliage and distinct seed clusters on female trees.
