Red knee tarantulas, scientifically known as Brachypelma smithi, are one of the most popular pet tarantulas due to their striking appearance and relatively docile nature. Understanding how often these spiders eat is essential for their care, whether they are in their natural habitat or in a terrarium as pets. In this comprehensive guide, we will explore the feeding frequency of red knee tarantulas, delve into their natural feeding behavior, and provide detailed advice on how to feed them properly in captivity.
Natural Feeding Patterns
The feeding patterns of red knee tarantulas in the wild are influenced by their natural behaviors and environmental conditions. This section will examine their diet, hunting methods, and how these factors dictate their feeding frequency.
Diet in the Wild
In their native habitats, which are typically dry and arid regions of Central America, red knee tarantulas have a diet primarily consisting of small arthropods. Their diet may include:
Crickets: These are a major food source for red knee tarantulas. Crickets provide necessary proteins and nutrients, helping the tarantula maintain its health and vitality.
Grasshoppers: These insects are another common prey item. They offer a different nutritional profile compared to crickets and add variety to the tarantula’s diet.
Beetles: Beetles are less frequently consumed but still provide essential nutrients and help diversify the tarantula’s diet.
Other Small Arthropods: This category includes various insects and small invertebrates that the tarantula encounters in its environment.
In the wild, red knee tarantulas eat opportunistically, meaning they feed whenever they have the chance to catch prey. The availability of food and the tarantula’s metabolic needs determine how often they eat. They can go for extended periods without eating if prey is scarce.
Hunting and Feeding Behavior
Red knee tarantulas are primarily nocturnal hunters, using their advanced sensory systems to detect prey. Their hunting and feeding behavior involves several key steps:
Ambushing the Prey: Red knee tarantulas are ambush predators. They typically remain still and wait for prey to come within striking distance. When the opportunity arises, they strike quickly to capture the prey.
Injecting Venom: Once the prey is captured, the tarantula uses its fangs to inject venom. This venom is crucial for immobilizing the prey and beginning the digestion process outside of its body.
Manipulating and Consuming: After injecting venom, the tarantula uses its chelicerae (jaw-like appendages) to manipulate and tear apart the prey. The digestive enzymes in the venom begin breaking down the prey’s tissues, making it easier for the tarantula to consume and absorb the nutrients.
This efficient feeding strategy ensures that red knee tarantulas can make the most of their feeding opportunities.
Feeding Frequency in Captivity
In captivity, the feeding frequency of red knee tarantulas needs to be adjusted to suit their needs, considering factors like age, size, and health. This section provides detailed guidelines for feeding red knee tarantulas at different life stages.
Young Tarantulas
Young Tarantulas
Young red knee tarantulas grow rapidly and have higher metabolic rates compared to adults. This rapid growth necessitates more frequent feedings:
Frequency: Young tarantulas should be fed every 2 to 3 days. This frequent feeding helps support their growth and ensures they receive the necessary nutrients for development.
Amount: Offer small insects such as pinhead crickets or small mealworms. These insects are appropriately sized for young tarantulas and provide the right balance of nutrients.
During their juvenile stages, red knee tarantulas are particularly voracious and require consistent feeding to maintain their growth rate.
Adult Tarantulas
Adult Tarantulas
As red knee tarantulas reach maturity, their growth rate slows, and their feeding needs change accordingly:
Frequency: Adult tarantulas generally need to be fed every 5 to 7 days. Their slower metabolism allows them to go longer between meals compared to juveniles.
Amount: Provide larger insects such as medium crickets or roaches. These insects are more suitable for adult tarantulas and provide the necessary sustenance without overloading them with excess food.
Adult tarantulas can manage with a less frequent feeding schedule and may occasionally skip a meal without adverse effects.

Factors Influencing Feeding Frequency
Several factors can influence how often red knee tarantulas need to eat. These factors include age, temperature, humidity, health, and prey availability.
Age and Size
The age and size of a tarantula play significant roles in determining its feeding frequency:
Young Tarantulas: Require more frequent feedings to support rapid growth and development. They have higher energy needs and a faster metabolism, necessitating regular meals.
Adult Tarantulas: Have slower metabolic rates and can sustain themselves with less frequent feedings. As they reach full size, their dietary needs become less demanding.
Adjust the feeding schedule based on the tarantula’s age and size to ensure it receives the appropriate amount of nutrition.
Temperature and Humidity
The environmental conditions within the tarantula’s enclosure are crucial for its overall health and feeding behavior:
Temperature: Red knee tarantulas thrive in temperatures between 75 to 85 degrees Fahrenheit. Proper temperature regulation is essential for maintaining their metabolic rate and appetite.
Humidity: Maintain humidity levels between 60% and 70%. Adequate humidity supports healthy molting and prevents dehydration, both of which can affect feeding behavior.
Inappropriate temperature or humidity levels can lead to changes in feeding patterns and overall health.
Health and Molting
A tarantula’s health status directly impacts its feeding behavior:
Healthy Tarantulas: Follow a regular feeding schedule and exhibit normal appetites. Ensure they are provided with a consistent diet to support their health.
Molting Periods: During molting, red knee tarantulas may refuse food. Molting is a critical phase in their life cycle where they shed their exoskeleton to grow. This process typically lasts a few days to a week, during which the tarantula may be less active and unwilling to eat.
Monitor your tarantula during molting periods and adjust the feeding schedule accordingly.
Prey Size and Availability
The size and availability of prey can influence how often red knee tarantulas eat:
Prey Size: Offer prey that is appropriately sized for the tarantula. Prey that is too large can be difficult for the tarantula to handle, while prey that is too small may not provide sufficient nutrition.
Prey Availability: If prey is scarce, the tarantula may go longer without eating. Ensure a steady supply of suitable insects to maintain a consistent feeding routine.
Providing properly sized and readily available prey helps maintain a balanced diet and feeding schedule.
Feeding Guidelines for Captive Tarantulas
Proper feeding practices are essential for the well-being of captive red knee tarantulas. Follow these comprehensive guidelines to ensure optimal care:
Provide a Balanced Diet
Offering a variety of insects helps ensure a balanced diet for your tarantula:
Crickets: A primary food source that provides essential proteins and nutrients.
Roaches: A nutritious option that offers different vitamins and minerals.
Mealworms and Waxworms: Additional sources of protein and fats, suitable for occasional variety.
A diverse diet helps prevent nutritional deficiencies and promotes overall health.
Avoid Overfeeding
Overfeeding can lead to health problems such as obesity and stress:
Follow Recommended Frequency: Adhere to the feeding schedule appropriate for your tarantula’s age and size.
Monitor Body Condition: Regularly check your tarantula’s body condition. Ensure it is neither overweight nor underweight.
Proper portion control is crucial for maintaining a healthy tarantula.
Monitor Feeding Behavior
Observing your tarantula’s feeding behavior provides insights into its health and well-being:
Signs of Healthy Eating: A tarantula that eats regularly and shows an appetite is generally in good health.
Signs of Issues: Persistent refusal to eat, weight loss, or unusual behavior may indicate health problems. Consult a veterinarian if you notice any concerning signs.
