What is a defining characteristic of Fall Webworm larvae?

The defining characteristic of Fall Webworm larvae is that they are hairy and exhibit a coloration that can range from yellow to black, often with distinct dark spots. This physical appearance helps in identifying them, as their hairy bodies are a trait that differentiates them from many other caterpillars. The presence of hair can indicate their stage of development and can also serve as a defense mechanism against predators. Their distinctive coloration and body structure are important for entomologists and pest control professionals when it comes to correctly identifying this pest and implementing effective management strategies. Recognizing these traits helps in distinguishing them from other similar species that might not have the same hairy texture or color patterns.
