Metacyrba Punctata (Dotted Jumping Spider) Care Sheet

Metacryba punctata, often referred to as the Dotted Jumping Spider, is a small and captivating species of jumping spider. As an active and curious predator, it displays typical judging spider behaviors like stalking, pouncing, and observing its surroundings. These spiders are known for their distinctive markings and engaging personalities, making them a popular choice among arachnid enthusiasts. Below is a comprehensive care guide to help you keep your Metacryba punctata healthy and thriving!

Basic Information

Scientific Name: Metacryba punctata

Common Name: Dotted Jumping Spider

Family: Salticidae (Jumping Spiders)

Size: Approximately 1-1.15 cm (body length)

Lifespan: 1-2 years (females generally live longer than males)

Native Range: Metacryba punctata can be found in various regions across Europe, Asia, and North America

Enclosure Setup

Terrarium Size: A 4x4x4inch enclosure will work fine as long as it has adequate space for the spider to move and climb. 

Substrate: Although substrate is not required, jumping spiders do not burrow, so a shallow substrate is all that’s needed if you choose to do so. Use a light substrate such as coconut fiber, peat moss, or even paper towels. Aim for a depth of around 1 inch.

Climbing Structures: Metacyrba punctata is an agile jumper, so it thrives in environments with plenty of vertical surfaces. Add branches, cork bark, silk plants, or even twigs to mimic its natural habitat. These structures will encourage climbing and jumping.

Hide: Although not as secretive as other species, providing a small hide such as a cork tube or rock is important. This gives your spider a place to retreat if it feels stressed or needs to rest.

Ventilation: Adequate ventilation is crucial to prevent mold and ensure airflow. Ensure your enclosure has small ventilation holes, especially if using a closed container.

Temperature and Humidity

Temperature: Metacyrba punctata does well at temperatures between 21-26°C (70-79°F). Room temperature is typically fine, but ensure the environment does not exceed 30°C (86°F), as this can stress the spider.

Humidity: These spiders thrive in moderate humidity levels between 50-60%. You can achieve this by lightly misting the enclosure 2-3 times a week. Make sure the humidity doesn’t get too high, as excessive moisture can encourage mold growth.

Diet and Feeding

Food: Jumping spiders are active hunters, and their diet should consist of live prey. Feed them small crickets, fruit flies, house flies, small roaches, or mealworms. The prey should be no larger than about half the size of the spider to ensure it can overpower it.

Feeding Frequency: Adult Metacyrba punctata should be fed 2-3 times a week. Younger spiders may require more frequent feedings. Always remove any uneaten food after 24 hours to prevent it from decomposing and causing harm.

Water: Provide a shallow water dish or mist the enclosure lightly with water droplets. Jumping spiders tend to drink from water droplets rather than large water bowls, but the dish still provides an essential water source.

Behavior and Interaction

Activity: Metacyrba punctata is known for being an active and curious spider. It will often be seen jumping, exploring its environment, or carefully stalking prey.

Interaction: While jumping spiders are not naturally aggressive toward humans, they may bite if threatened or handled improperly. Their bites are not dangerous but can cause mild irritation.

Solitary Nature: Like most jumping spiders, Metacyrba punctata is solitary and should not be housed with other spiders. Housing multiple individuals in the same enclosure can lead to territorial disputes and potential aggression.

Intelligence: One of the most engaging aspects of jumping spiders is their curiosity. They are often seen observing their surroundings and may even “look” at you if you approach their enclosure.

Molting and Growth

Metacyrba punctata, like other arachnids, undergoes ecdysis (molting) as it grows. During this process, the spider will shed its exoskeleton to allow for further growth. Molting typically takes several days, and the spider will be sluggish and vulnerable during this time.

Ensure the spider has a quiet, secure space during molting. Afterward, the spider’s new exoskeleton will harden, and it may be inactive for a short period. Do not disturb the spider during this time to avoid stress or injury.

Common Health Issues

Dehydration: If the spider is lethargic, refuses food, or appears shriveled, it may be dehydrated. Ensure humidity is maintained, and provide fresh water regularly. Misting their enclosure will aid in this.

Obesity: While jumping spiders can eat large prey items, overfeeding can cause obesity, leading to lethargy or shorter lifespans. Offer appropriately sized prey and feed in moderation.

Mites: Occasionally, mites may infest the enclosure, especially if conditions are too moist. Keep the enclosure clean, remove uneaten food, and avoid overwatering to prevent mite problems.

Mold: Mold can occur if humidity is too high or if the enclosure is not properly ventilated. Regular cleaning and proper humidity control will help prevent mold growth.

Breeding and Reproduction

Mating Behavior: Male Metacyrba punctata will court females through vibrations and displays, often offering a small prey item. Females are generally receptive to males when in the right mood, but they can be aggressive, especially after mating.

Egg Sac and Spiderlings: After mating, the female will lay an egg sac, which she will guard. The sac may contain dozens of eggs, and after several weeks, the spiderlings will emerge. These young spiders are tiny and will need to be separated from the mother once they begin to disperse.

Raising Spiderlings: If you want to raise the spiderlings, ensure they have enough food, space, and vertical surfaces to climb. Juvenile jumping spiders can be fed tiny fruit flies or small insects.

Conclusion

Metacyrba punctata is a delightful and low-maintenance species of jumping spider, perfect for beginner and intermediate keepers alike. With its fascinating hunting techniques, curious nature, and manageable size, it makes for a wonderful pet. By providing a safe, well-ventilated enclosure with climbing structures, appropriate food, and a stable environment, your Dotted Jumping Spider will thrive and become a source of endless fascination.

Enjoy observing this energetic little hunter and give it plenty of opportunities to leap, explore, and live a healthy life!
