Body Size and Shape
Females are more likely to be larger than males, especially when the females carry eggs in their abdomen. The size difference could be observed in the abdomen usually, and that determines a characteristic shape for the egg-carrying females among males. It would be important to notice the presence of the ovipositor in the female abdomen, but it is not present in males at all. There are two protruded tubes in the abdomen of both males and females, but the ovipositor in female appears as the third protrusion bisecting the other two. Therefore, these tubes offer a highly reliable indication whether a cricket is a male or a female.
