Evaluating the Grasshopper's Appearance

Knowing the gender of a grasshopper is essential for research or dissection purposes. Despite the lack of obvious physical differences, distinguishing between male and female grasshoppers is achievable. By examining their abdomen and observing their behavior, you can determine the sex of the grasshopper!

Steps

Examining the Abdomen

Secure the grasshopper in the middle of its body with your fingers. Gently grasp the grasshopper to ensure a secure hold. Be cautious not to apply too much pressure to avoid injuring the grasshopper. While handling, be aware that grasshoppers rarely bite and may regurgitate their stomach as a defense mechanism, which poses no threat to humans.

Gently press on the grasshopper’s abdomen. Using your thumb and forefinger, lightly squeeze the rear part of the grasshopper to expose its sexual organs.

Applying too much pressure can harm the grasshopper.

Identify a male grasshopper by its rounded abdomen. Examining the shape of the abdomen is the most reliable method to determine the grasshopper’s sex. A rounded, upward-curving abdomen signifies that the grasshopper is male.

Observe that a female grasshopper possesses a tapered abdomen. The abdomen of a female grasshopper appears cylindrical, housing the ovipositor, which the female employs for egg-laying.

Evaluating the Grasshopper's Appearance

Take note that female grasshoppers exhibit larger body size compared to males. When assessing a grasshopper within a group, pay attention to its size relative to others of the same species. If the grasshopper appears larger than its counterparts, it is likely a female. Otherwise, it is probably a male.

However, refrain from solely relying on visual cues to determine the sex of the grasshopper as it may not always be accurate.

Recognize male grasshoppers by their aggressive behavior. Look for signs such as kicking or biting among members of the same species. During mating season, males may exhibit heightened aggression as they vie for females.

Aggression levels vary among grasshopper species, with some being more aggressive than others.

Observe males mounting females during mating. When grasshoppers mate, males typically climb atop females to deposit sperm for egg fertilization. If you see a smaller grasshopper on top of a larger one, it's likely a male.

Occasionally, males may mount other males during fights.

Identify a female grasshopper by observing egg-laying behavior. Look for signs such as the grasshopper inserting its abdomen into the ground. Female grasshoppers lay eggs underground, so watch for them digging or remaining motionless when approached.

Female grasshoppers lay eggs throughout the summer and autumn seasons.

If you need to catch a grasshopper but don't have a bug net, approach it quietly from behind and swiftly cup your hands around its body. Wait quietly until you feel it jump to know if you've caught it.
Remember, like humans and animals, grasshoppers can experience stress. Avoid handling them excessively, whether you're trying to determine their sex or for any other reason.
Do not house grasshoppers in a netted terrarium, as they have the ability to chew their way out of the enclosure.
