Have you heard of spotted lanternflies? In 2014 the invasive species native to Asia was found in Pennsylvania.
During the fall these bugs lay from 30-50 eggs each. Without action these insects can take over areas.
Spotted lanternflies cause damage to the plants around them. They also produce a substance that causes black sooty mold.
Adult spotted lanternflies are about 1" long and 1/2" wide. The top wing is a grey tone with black spots and the hind wings have a vibrant red color with black dots.
