As the egg masses age, they crack and fade to a tan or grayish brown over time. New egg masses appear to be coated with a shiny grayish substance that initially resembles fresh concrete. Egg masses, each containing 30-50 eggs, are laid on tree trunks or branches but also on other types of hard or solid objects such as bricks, vehicles and landscape boulders. Spotted lanternfly overwinters in the egg stage. A few adults may appear in mid-summer, but they are most common in late summer and fall. When the wings are extended, the red, white and black hindwings can be seen. The grayish forewings have black spots and markings.
An adult SLF is about an inch long and half an inch wide. Fourth instar nymphs, however, have striking reddish-orange bodies with black and white markings.Īdults, the only stage with wings, begin to appear in late summer and are active through early fall. First, second and third instar nymphs are black with white markings. Spotted lanternfly has one generation per year via incomplete metamorphosis with four immature development stages or “instars” before becoming adults. Photo by Lawrence Barringer, Pennsylvania Department of Agriculture,. Adult spotted lanternfly showing the flashy red hindwings. In reality, the snouts don’t actually glow but species with names like “peanut bug,” “angry bride,” and “unicorns of the insect world” are worth checking out online! Adult spotted lanternfly. Apparently, there are old folk tales that mention lanternflies with long snouts that glow in the dark – hence the “lantern” in the name lanternfly. Adult lanternflies are often amazing, with bright colors and a crazy long snout. Most lanternflies are large insects that feed on trees in tropical regions of the world. Fewer than 20 species are native to the U.S. Spotted lanternfly and other lanternflies are planthoppers in the family Fulgoridae, which includes approximately 140 genera and 716 species. The pests - which are native to Asia and known for their pale, pinkish gray wings, black dots and scarlet undercoat - were first documented in Pennsylvania in 2014.Spotted lanternfly (SLF) ( Lycorma delicatula) is a native of China and other regions of Asia. The best course of action and advice to New Yorkers is to stomp on the bugs when you see them. Logue said we are past the egg-scraping point in their lifecycle, so now it's important for people to stomp or vacuum up the eggs as they hatch and as the spotted lanternflies mature. The biggest concern is still for the insect's destructive impact on agriculture - specifically New York State's grape industry, as grapes seem to be a favorite for the flies. We may find that we have a little bit of an early hatch in other parts of the state as well, I will say obviously New York City is a little bit, is a little bit warmer, so you also have sort of the urban heat sake effect which again probably influenced that earlier emergence as well." "And we were able to go out to those locations and actually confirm that the early instar juvenile spotted lantern fly had emerged in those areas. "However this year it's been a little bit earlier, and we did get reports of emergence in a couple of locations in New York City here last week," Logue said.
