What is the typical length of Fall Webworm larvae?

The typical length of Fall Webworm larvae is approximately 1.5 inches when they reach maturity. This measurement reflects the larger, fully grown larvae, which can vary slightly in size depending on the specific conditions and individual growth rates. Notably, Fall Webworms undergo several instars, and their size can increase significantly as they progress through these developmental stages. Understanding the typical size of these larvae can help in identifying them correctly and managing them effectively in landscaping and turf management practices.
