You make a good point, and I hadn't thought of that. Still, I'm unsure if simply having four arms and insect-like mandibles qualifies them as more like insects than humans (Elites in Halo have similar mandibles and are not considered insectoids). To our knowledge, they do not share any other physical characteristics of insects, such as exoskeletons or antennae. Therefore, I think Fallen are more simply and accurately described as humans with a few insect traits than insects with a few human traits (for example, like this race from Master of Orion II).

Of course, I'm no expert in morphology, so let me know what you think.
