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]
Snow goose This goose breeds north of the timberline in Greenland, Canada, Alaska, and the northeastern tip of Siberia, and spends winters in warm parts of North America from southwestern British Columbia through parts of the United States to Mexico. They fly as far south as Texas and Mexico during winter, and return to nest on the Arctic tundra each spring.[6] It is a rare vagrant to Europe, but a frequent escape from collections and an occasional feral breeder. Snow geese are visitors to the British Isles where they are seen regularly among flocks of barnacle, Brent and Greenland white-fronted geese. There is also a feral population in Scotland from which many vagrant birds in Britain seem to derive.
