The ventricose shape of the gullet allowed the insect to store more food.
Ventricose → It is formed from "ventriculus" (meaning little belly or cavity) and the suffix "-ose" (meaning full of or characterized by). The word "ventricose" describes something that is swollen or full, particularly in reference to a cavity or chamber.
Think of a 'little belly' ('ventriculus') being 'full' ('-ose') — that's why ventricose refers to something that is swollen or full.
