Spotted Lanternfly

Fascinating facts about the Spotted Lanternfly

• The lanternfly's diet is a buffet of over 173 plant species worldwide, with 103 plant taxa spanning 33 families and 17 orders. In the United States alone, 56 of those hosts are recorded, ranging from grapes to maples. Such a broad menu lets the insect thrive in many habitats, turning almost any green space into a potential feeding ground and making control far more difficult.
• Each egg mass holds 30 to 50 embryos, wrapped in a sticky, gray-brown wax that looks like mud. Eggs need a chilling period to break diapause; two weeks of warm weather after winter triggers hatching. They survive temperatures down to about -12.7 °C, but at -25 °C virtually none hatch.
• The first U.S. sighting was on 29 September 2014 in Berks County, Pennsylvania, but egg clues suggest the bug arrived as early as 2012, likely hitchhiking on stone shipments. Within seven years it spread to 34 of Pennsylvania's 67 counties, illustrating how a single unnoticed introduction can explode into a regional pest in just a few seasons.
• Feeding creates tiny wounds and a flood of sugary honeydew that coats leaves, inviting black sooty mold. The mold blocks sunlight, slashing photosynthesis and weakening the plant. This double assault, physical damage plus mold-induced shading, explains why infestations can kill vines and trees, threatening crops and forest health alike.
• Adult spotted lanternflies are about the size of a thumb nail, measuring roughly 25 mm long and 12 mm wide, but females grow noticeably larger than males. Females range from 20 to 27 mm, while males stay between 21 and 22 mm.
