They have black bodies and transparent gray forewings with black spots and black wing tips. Their hindwings are bright red and highly visible when the lanternfly\u2019s wings are open. Spotted lanternfly are planthoppers which means they are extremely fast. They can also fly short distances, but their primary mode of transportation is jumping or hitchhiking.<\/p>\n\n\n\n<p>Females lay eggs from September to December. Egg masses are roughly 1.5 inches long and typically covered in a gray, mud-like substance. They may be laid on a variety of surfaces such as trees, houses, rocks, etc, and each egg mass contains between 30-50 eggs.&nbsp;<\/p>\n\n\n\n<p>Once hatched, spotted lanternfly first instar nymphs are about 1\/8 an inch long. They have black bodies with white spots on their back. As they grow into second and third instar nymphs, they retain their black bodies and white spots, and increase in size with every molt. In contrast, their fourth instar form is about 1\/2 an inch long with a bright red body, black stripes and white spots. Similarly to adult SLF, nymphs are very fast and can jump far, however are unable to fly.&nbsp;<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-large is-resized\"><a href=\"https:\/\/web.uri.edu\/biocontrol\/wp-content\/uploads\/sites\/2154\/Screen-Shot-2022-09-15-at-11.13.07-AM.png\" rel=\"lightbox[602]\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/web.uri.edu\/biocontrol\/wp-content\/uploads\/sites\/2154\/Screen-Shot-2022-09-15-at-11.13.07-AM.png\" alt=\"\" class=\"wp-image-613\" width=\"789\" height=\"580\" srcset=\"https:\/\/web.uri.edu\/biocontrol\/wp-content\/uploads\/sites\/2154\/Screen-Shot-2022-09-15-at-11.13.07-AM.png 864w, https:\/\/web.uri.edu\/biocontrol\/wp-content\/uploads\/sites\/2154\/Screen-Shot-2022-09-15-at-11.13.07-AM-300x220.png 300w, https:\/\/web.uri.edu\/biocontrol\/wp-content\/uploads\/sites\/2154\/Screen-Shot-2022-09-15-at-11.13.07-AM-768x564.png 768w, https:\/\/web.uri.edu\/biocontrol\/wp-content\/uploads\/sites\/2154\/Screen-Shot-2022-09-15-at-11.13.07-AM-364x268.png 364w, https:\/\/web.uri.edu\/biocontrol\/wp-content\/uploads\/sites\/2154\/Screen-Shot-2022-09-15-at-11.13.07-AM-500x367.png 500w\" sizes=\"auto, (max-width: 789px) 100vw, 789px\" \/><\/a><figcaption>SLF Identification Guide.
