Types Of Spiders That Eat Grasshoppers

There are many types of spiders that eat grasshoppers! One species in imparticular is the mighty tarantula! Tarantulas will usually eat any type of grasshopper and in their case, the larger the grasshopper, the better.

Types Of Grasshoppers Spiders Shouldn’t Avoid Eating

There are also some types of grasshoppers that you should avoid feeding to your spider. For example, try to stay away from grasshoppers that you have found in your garden.

This is because they may have been sprayed with pesticides or other chemicals from nearby farms which can be harmful to your spider if consumed.

Also, there are some grasshopper species that are becoming endangered in some areas. In fact, there has been a decrease in the number of certain grasshopper breeds.

While the reasons for this decline are not fully understood, it’s thought that the changes in their environment may be to blame.

For example, the use of pesticides can reduce the number of insects available for spiders to prey on. Additionally, warmer temperatures can cause some grasshoppers to breed less frequently.

Whatever the cause, you should only feed your spider grasshoppers that are common in your area and not at risk of decline.

Here are some examples of grasshoppers that spiders should avoid:

Benefits Of Feeding Your Spider Grasshoppers

There are many benefits to feeding your spider grasshoppers! For one, grasshoppers are an excellent source of protein and other nutrients that are important for your spider’s health.

Plus, as before, grasshoppers are relatively easy to find and generally affordable, making them a great option for pet owners on a budget. And the variety of grasshopper species available means that there is something for almost any spider.

Grasshoppers Provide Spiders With The Following:

  • Fat: Like all animals, spiders need certain nutrients to survive, and fat is one of the most essential. Fat provides spiders with energy, helps to insulate their bodies, and aids in the production of new cells. 
  • Calcium: Spiders also need to consume a diet that is high in calcium and grasshoppers are one of the best sources of this essential nutrient. Calcium helps with the spider’s growth by building a strong exoskeleton.
  • Protein: All animals need some source of protein in their diet, and spiders are no different and require Amino acids in their diet. In the wild, spiders typically eat insects or other small animals with high protein. This is what helps spiders to grow and repair damaged tissue.
  • Gluconeogenesis: Spiders also rely on a process called catabolism, which breaks down amino acids and other nutrients into usable energy. Gluconeogenesis is a similar process that helps to produce glucose from non-carbohydrate sources. Together, these two processes provide the majority of the energy that spiders need to survive.

How Many Grasshoppers Can They Eat?

Spiders can live on a very small meal, which is one of the reasons they are able to survive in areas with little food. In fact, a spider only needs to consume about two meals a week to stay alive.

However, this doesn’t mean that spiders only eat when they are hungry. In the wild, spiders will typically catch prey and then wrap it up in silk to save for later.

This allows them to have a steady food supply and helps them to survive times when prey is scarce. It also means that they can eat more than usual when prey is abundant.

So, when feeding your spider grasshoppers, one every couple of days should be plenty. This should help to ensure that your spider stays healthy and doesn’t become overweight.

How To Feed Grasshoppers To Your Pet Spider?

If you have a pet spider and would like to feed it grasshoppers, there are a few things you need to do first. The most important thing is to make sure the grasshoppers are healthy and free from pesticides or diseases.

If you’re buying them from a pet store, they should already be safe. But if you’re catching them yourself, then you need to make sure they’re from a pesticide-free area. Once you have your grasshoppers, you simply place one in your spider’s enclosure near their nest.

Some spiders will eat the grasshopper straight away. But others may take a while before they’re ready to eat them. It all depends on your spider and whether or not it’s hungry!

Can Grasshoppers Sense When Spiders Are Close?

Yes, grasshoppers can sense when spiders are close. In fact, there was a study by the University of Jerusalem and Yale University in the US that discovered grasshoppers actually show signs of stress when they sense a spider close by.


So, while most spiders will eat grasshoppers if given the chance, not all of them can actually catch them. And of those that can, not all of them should because of the risk of pesticide poisoning.

However, if you have a problem with grasshoppers in your garden then these spiders can actually be quite helpful!
