Fall armyworm (Spodoptera frugiperda) was first detected in Australia in early 2020. Here we show an example of what an advanced instar larvae looks like and provide a couple of quick points of visual comparison against other armyworm and Helicoverpa larvae.
Note that individual caterpillars can vary widely in their colouration and patterning; the larvae shown and ID suggestions are included as examples only and should not be used as the only basis of identification.
