## Choosing Your Grasshopper Species

Not all grasshoppers are created equal when it comes to breeding in captivity. Some species are more adaptable, easier to care for, and reproduce more readily than others. Here are a few popular choices:

* **Migratory Grasshopper ( *Melanoplus sanguinipes*):** This is a common and widely distributed species, known for its adaptability and ease of breeding. They are relatively small, making them suitable for smaller enclosures.
* **Two-Striped Grasshopper (*Melanoplus bivittatus*):** Another readily available and easily bred species. They are slightly larger than the Migratory Grasshopper.
* **Differential Grasshopper (*Melanoplus differentialis*):** A larger species that requires more space but is still relatively easy to breed. They consume a larger amount of vegetation.
* **Locusts (Various species, e.g., *Schistocerca gregaria*):** While technically grasshoppers, locusts are known for their swarming behavior. Breeding them requires larger enclosures and more careful management to prevent escapes. Exercise caution and research thoroughly before considering locusts, as some areas have regulations regarding their keeping.

**Important Considerations:**

* **Legality:** Before acquiring any grasshopper species, check your local regulations to ensure it’s legal to keep and breed them. Some areas may restrict the possession of certain species, especially those considered pests.
* **Availability:** Choose a species that is readily available from reputable breeders or suppliers. Wild-caught grasshoppers can carry diseases and parasites, making them less suitable for breeding programs.
* **Diet:** Research the specific dietary needs of the chosen species. Ensure you can provide a consistent supply of appropriate food throughout the breeding cycle.

## Setting Up the Grasshopper Habitat

The habitat is crucial for successful grasshopper breeding. Here’s what you’ll need to create a suitable environment:

* **Enclosure:**
* **Size:** The size of the enclosure depends on the number of grasshoppers you plan to breed and the species you’ve chosen. A good starting point is a 20-gallon aquarium or a similar-sized plastic container with a secure lid. Larger enclosures are always better, as they provide more space for the grasshoppers to move around, reducing stress and the risk of cannibalism.
* **Material:** Glass or plastic containers are suitable. Avoid metal containers, as they can overheat in direct sunlight.
* **Ventilation:** Proper ventilation is essential to prevent the build-up of humidity and harmful gases. The lid should have ample ventilation holes covered with fine mesh to prevent escapes.
* **Secure Lid:** Grasshoppers are excellent jumpers, so a secure lid is crucial to prevent escapes. Ensure the lid fits tightly and is made of a material that the grasshoppers cannot chew through. Fine mesh is essential to cover any ventilation holes.
* **Substrate:**
* **Purpose:** The substrate serves several purposes: providing a surface for the grasshoppers to walk on, absorbing moisture, and offering a place for females to lay their eggs.
* **Suitable Options:**
* **Peat Moss:** A good choice for retaining moisture and providing a soft surface for egg-laying.
* **Coco Coir:** Similar to peat moss, coco coir is a sustainable alternative made from coconut husks.
* **Sand:** Can be used alone or mixed with other substrates. Ensure the sand is clean and free of chemicals.
* **Vermiculite:** Helps retain moisture and provides a good medium for egg incubation.
* **Soil:** Use pesticide and fertilizer-free topsoil. Sterilize it by baking it in the oven at 200°F (93°C) for 30 minutes to kill any harmful organisms.
* **Depth:** The substrate should be at least 2-3 inches deep to allow females to bury their eggs.
* **Climbing Structures:**
* **Purpose:** Grasshoppers need climbing structures to molt properly and to provide vertical space within the enclosure.
* **Suitable Options:**
* **Branches:** Natural branches from pesticide-free trees are ideal. Sterilize them by baking them in the oven or soaking them in a diluted bleach solution (followed by thorough rinsing) before placing them in the enclosure.
* **Twigs:** Smaller twigs can be used to create a more complex climbing structure.
* **Artificial Plants:** Plastic plants can be used as a supplement to natural branches, but ensure they are non-toxic and easy to clean.
* **Mesh Walls:** Attach mesh to the sides of the enclosure to provide additional climbing surfaces.
* **Lighting and Heating:**
* **Lighting:** Grasshoppers need a natural day/night cycle to thrive. Provide 12-14 hours of light per day using a fluorescent or LED light. Avoid using incandescent bulbs, as they can generate too much heat.
* **Heating:** Grasshoppers thrive in temperatures between 80-95°F (27-35°C). Use a heat lamp or a heating pad placed on the side of the enclosure to maintain the optimal temperature gradient. Monitor the temperature regularly with a thermometer to ensure it doesn’t get too hot or too cold. Create a temperature gradient, so the grasshoppers can move to their preferred temperature.
* **Humidity:**
* **Importance:** Proper humidity is essential for successful molting and egg incubation.
* **Maintaining Humidity:** Maintain humidity levels between 50-70% by misting the enclosure with water once or twice a day. Use a hygrometer to monitor the humidity levels. Avoid over-misting, as this can lead to fungal growth.
* **Food and Water:**
* **Food:** Grasshoppers are herbivores and require a constant supply of fresh vegetation. The specific diet depends on the species, but common options include grasses, leaves, and vegetables.
* **Water:** Provide water by misting the enclosure daily. Grasshoppers will drink the water droplets from the plants and the sides of the enclosure. You can also provide a shallow dish of water with pebbles in it to prevent the grasshoppers from drowning.

## Feeding Your Grasshoppers

Proper nutrition is vital for healthy grasshoppers and successful breeding. Here’s a detailed look at what to feed your grasshoppers:

* **Dietary Requirements:** Grasshoppers are primarily herbivores, so their diet should consist mainly of fresh vegetation. The specific dietary needs vary depending on the species, but a good general rule is to provide a variety of grasses, leaves, and vegetables.
* **Suitable Food Options:**
* **Grasses:** A staple food for most grasshopper species. Provide a variety of grasses, such as Bermuda grass, Timothy grass, and orchard grass. Ensure the grasses are free of pesticides and herbicides.
* **Leaves:** Offer a variety of leaves, such as dandelion leaves, clover leaves, and lettuce leaves. Avoid feeding them poisonous plants. Do thorough research on what plants are toxic to grasshoppers.
* **Vegetables:** Supplement their diet with vegetables like carrots, sweet potatoes, and squash. Cut the vegetables into small pieces to make them easier to eat.
* **Commercial Grasshopper Food:** Some commercial grasshopper foods are available, but they should be used as a supplement to a fresh diet, not as a replacement.
* **Frequency and Amount:** Feed your grasshoppers daily, providing enough food that they can consume within 24 hours. Remove any uneaten food to prevent it from rotting and attracting pests.
* **Water:** Grasshoppers get most of their water from the food they eat, but it’s still important to provide a source of fresh water. Misting the enclosure daily will provide enough water for them to drink.
* **Supplements:** You can supplement their diet with calcium and vitamin supplements to ensure they are getting all the nutrients they need. Dust their food with the supplements once or twice a week.
* **Avoiding Harmful Foods:**
* **Pesticides and Herbicides:** Never feed your grasshoppers food that has been treated with pesticides or herbicides, as these chemicals can be harmful or even fatal.
* **Poisonous Plants:** Avoid feeding them poisonous plants, as they can also be harmful or fatal. Research to ensure you are not feeding them anything that could hurt them.
* **Moldy or Rotten Food:** Do not feed them moldy or rotten food, as it can cause them to get sick.

## Breeding Process: From Mating to Hatching

Once you have a healthy population of adult grasshoppers, you can begin the breeding process. Here’s a step-by-step guide:

* **Identifying Sexes:**
* **Size:** Females are typically larger than males.
* **Abdomen:** Females have a pointed abdomen with visible ovipositor valves (used for laying eggs), while males have a rounded abdomen.
* **Sound:** Males of some species produce chirping or buzzing sounds to attract females.
* **Mating:**
* **Courtship:** Males will typically court females by displaying their wings and antennae. They may also produce sounds to attract the females.
* **Process:** Mating usually occurs in a head-to-tail position, with the male attaching a spermatophore (a packet of sperm) to the female’s abdomen.
* **Duration:** Mating can last for several hours.
* **Egg Laying:**
* **Preparation:** The female will search for a suitable location to lay her eggs. She prefers moist soil or sand.
* **Process:** The female will use her ovipositor to dig a hole in the substrate and deposit her eggs. She will then cover the eggs with soil or sand.
* **Egg Pods:** Grasshoppers lay their eggs in clusters called egg pods. Each egg pod can contain dozens or even hundreds of eggs.
* **Frequency:** Females can lay multiple egg pods throughout their lives.
* **Egg Incubation:**
* **Temperature:** The optimal incubation temperature varies depending on the species, but generally falls between 80-90°F (27-32°C).
* **Humidity:** The optimal incubation humidity is around 60-70%.
* **Duration:** The incubation period can last from several weeks to several months, depending on the species and the environmental conditions.
* **Methods:** You can incubate the eggs in the same enclosure where they were laid or transfer them to a separate incubator. If you transfer them, make sure to maintain the proper temperature and humidity levels. You can use an incubator that is designed for reptile eggs.
* **Hatching:**
* **Process:** The nymphs (baby grasshoppers) will hatch from the eggs and begin to feed on vegetation.
* **Nymph Stage:** Nymphs go through several molts as they grow. They look like smaller versions of the adults, but without wings.
* **Care:** Provide the nymphs with the same food and care as the adults. Make sure the enclosure is escape-proof, as the nymphs are small and can easily squeeze through small openings.

## Monitoring and Maintaining the Habitat

Regular monitoring and maintenance are crucial for the health and well-being of your grasshoppers. Here are some important tasks:

* **Daily Checks:**
* **Food and Water:** Ensure there is always a fresh supply of food and water available.
