Grasshopper also referred to as jumping insect, belongs to the “Caelifera” suborder. They live in different habitats. They have different colours ranging from green to olive and brown, some have yellow or red spots.
Kinds of Grasshoppers
LongHorn: These grasshoppers have long antennae,together with two ‘feelers,’ equal to their body length.
ShortHorn: These grasshoppers’ antennae are quarter to their body size. Due to migration
called Locust. When finding food during migration destroyed many fields.
Body Features of grasshopper
- They are mostly of “green,” “brown,” and “grey” in colour.
- The average weight of a grasshopper is about 300mg
- The length varies from 1.3 cm to 15 cm.
- The size of female grasshoppers is greater than male grasshoppers.
Grasshopper life cycle: All stages
Generally, they reproduce in summers. During mating, male grasshoppers transfer sperms in the female “ovipositor” abdomen. Fertilization happens when sperms combine with eggs.
EggStage: From this stage, the life cycle starts. Female grasshopper lays fertilized eggs under the sand or the leaves. After deposition of eggs with ovipositor, then hard egg pods are formed. These egg pods contain about 10 to 300 eggs, more than ten egg pods. These egg pods remain inactive for about ten months in the winter and autumn seasons. These eggs convert into a nymph by the start of the spring season.
Nymph Stage: This is the second stage of the lifecycle when eggs are hatch, and they start eating soft, juicy, and moist plants. Nymphs are tiny grasshoppers, and they don’t have wings, and their color is light. There is 5 to 6 molt for their transformation to become adults. Depending on species, humidity, and temperature, this stage lasts for 5 to 10 days. During molting, there is an increase in body size, and wings develop on the “thorax” body part.
Adult Stage: The wings completely develop in this stage, and the nymph is changed to adult. During the change from egg to mature, the grasshopper is of eleven months. An adult gains
maturity in 15 days. Their survival span is for 30 days. They have wings and can hunt food and protect themselves from predators.
Grasshoppers live for 12 months. After hatching, a nymph has a 50% chance of survival. Grasshoppers play an essential role in the ecosystem by becoming food of predators to complete the food chain.
Parts of body
The body parts of grasshoppers are the “Head,” “Thorax,” and “Abdomen.”
It consists of eyes, mouth, and antennae. Their mouth is specially designed such that the jaws move to-and-fro in the direction only. A tasting organ is used for tasting.
Parts of Mouth
- Upper Lip (Labrum): The structure is rectangular, rough, and wide, holding the food.
- Hypo pharynx: It is like a tongue that is present with the Labrum.
- Mandibles: It is a triangular structure that is hard, big, heavy with rough edges, each present on both sides. It moves horizontally and crushes the food.
- Maxillae: It is present in the pair back side of Mandibles.
- Labium: It is the lower lip that consists of many parts on each side. It also holds the food between the Mandibles and Maxillae.
There are five eyes of Grasshoppers. It has large eyes on either side. These eyes are made of many lenses. These lenses are used to complete the picture. It can sense the vision and can change the perceived light intensity.
Two antennas are present on the head of the body: shorthorn and longhorn. Shorthorns point the forward direction. In comparison, longhorns are curved towards the back of the body.
It is the central boy part of the grasshoppers. The wings and the legs (Three pairs) are joined with Thorax. Hind legs are thick, long, and muscular thighs through which grasshoppers can jump, and their flying speed is 8 miles/hour.
There are four wings present on the Thorax. When wings are not in use, they are folded backwards lengthwise. Longhorn grasshoppers have hearing organs that are present on the front legs below the knees. While in Shorthorn grasshoppers, these organs are present in the abdomen under the wings.
“Spiracles” are small breathing holes that are present in the body. There are ten spiracles pairs of grasshoppers. From the body, front holes take in the air, and back holes take out the air.
There are eleven segments in the abdomen. The first segment, “Metathorax,” is attached. There is an “auditory organ” with an eardrum cover (Tympanum).
The abdomen of female grasshoppers is triangular in shape and sharp-pointed end.
The male abdomen has a single unpaired plate that has the reproductive organ (Genitalia).
Grasshoppers have a hearing organ (Tympanal) present at the bottom of the abdomen. It has an open circulatory system. There is a heart and hemolymph in the abdomen. They have a rigid exoskeleton structure. They have Green Blood because they do not carry oxygen.
Grasshopper’s lifecycle is unpredictable. They play an essential role in the food chain mechanism. The life cycle of grasshoppers takes less time, and their life span is about one year. They have many enemies, such as lizards, rodents, and birds. A swarm can cause more significant damage to crops in large amounts. They have the highest population in warm and cool areas.
- Why do the grasshoppers jump?
Grasshoppers jump because their hind legs are long. They can telescope the incoming predators.
- What is Locust?
Locust has long and strong wings through which it has better flight properties and is smaller in size than grasshoppers.
- Is poison present in grasshoppers or not?
Grasshoppers are not poisonous; infact, they have a chemical defence system in their body for predators. They emit a terrible odour for the repulsion of predators.
- What to feed Grasshoppers in Captivity?
They can be fed young plants as their favorite plants are fresh reed and canary grass.
- Where are grasshoppers mostly found?
They are primarily found in lowland tropical forests and grasslands.
- How many species of grasshopper are there?
There are more than 10000 known species.
- From which group of insects do the grasshoppers belong to according to Wikipedia?
According to Wikipedia, The grasshopper, a group of insects, belongs to the suborder “Caelifera.”
