The things that really do distinguish fall armyworm are the dots on the back of the body. As they get bigger, they get darker and more pronounced on the head capsule. If you were to use a hand lens or something, you can see that the head capsule is mottled and then there's an inverted Y, sort of between the eyes on the. On the front of the head. There's some behavioural things about them. You know, they want to get away and get out of the sun. Helica Verpa are not so fussed about that. And then the native armyworms will tend to curl up in your hand, whereas fall armyworm don't tend to do that Quite, quite so much. Helica very aggressive. Fall army worm, not so much. Won't spit on you like Helica Verpa do. So, you know, these little things that people will learn from the experience help them to distinguish them as well.
