do spotted lantern flies die in the winter
Spotted lanternfly Beginning in late April to early May, nymphs hatch from their egg cases. A nymph passes through several immature stages. In the first stage it is wingless and looks black with white spots. It then grows red patches in addition to the white spots. Next, it has red wing pads and a red upper body, before assuming the adult look of black head and grayish wings with black spots.[2] Nymphs cannot fly, so they hop or crawl to search for plants to feed on.[4] Young nymphs appear to have a wider host range early on, which narrows as they grow older.[2] As early as July, adults can be seen. In the fall, adults mate and lay eggs from late September through the onset of winter. In their native Indomalayan habitat they will lay their eggs preferably on the Tree of Heaven (Ailanthus altissima), which is an introduced invasive tree with toxic metabolites. This host choice is thought to have evolved as mechanism of protection from natural enemies.[2] The lanternfly will lay eggs upon any smooth trunked tree, stone or vertical smooth surface, including man made items like vehicles, campers, yard furniture, farm equipment or other items stored outside.[4] The egg masses contain 30-50 eggs,[6] covered in a yellowish brown waxy deposit, the egg case.[2] The lanternfly's life expectancy, is one year.[2]
Trumpeter swan In the winter, they migrate to the southern tier of Canada, the eastern part of the northwest states in the United States, especially to the Red Rock Lakes area of Montana, the north Puget Sound region of northwest Washington state;[18] they have even been observed as far south as Pagosa Springs, Colorado. Historically, they ranged as far south as Texas and southern California.[19] In addition, there is a specimen in the Museum of Comparative Zoology at Cambridge, which was shot by F. B. Armstrong in 1909 at Matamoros, Tamaulipas, Mexico.[20] Since 1992, trumpeter swans have been found in Arkansas each November â€“ February on Magness Lake outside of Heber Springs.[21] In early 2017, a juvenile trumpeter swan took up residence in the French Broad River in Asheville, North Carolina, marking the first such sighting in that part of the state.[22]
