With a bulging blue and black striped torso and long, skinny, pointy legs that easily stretch the surface of a tennis ball, the Joro Spider will leave anyone running for the hills. Scientifically known as Trichonephila Clavata, the Joro spider is an East Asian arachnid species that has recently made its presence known in the Southeastern United States, with potential expansion to areas like New Jersey.But, is this 8-legged arachnid a real threat? Let’s take a closer look.
What is the Origin of the Joro Spider?
The Trichonephila clavata, or East Asian Joro Spider, is a native to countries such as Japan, Korea, Taiwan, and China. However, in recent years these spiders have ventured beyond their native homes. In 2010,Joro spiders were first sighted in the United States, having first made their way to the state of Georgia. The University of Georgia's research confirmed the presence of Joro spiders in the state, tracing their arrival to cargo shipments.In the case of the Joro Spider, their journey to the United States likely commenced on shipping containers which showcases their adaptability and ability to make use of human-mediated transportation. But it does not end there. The spread of the Joro Spider in the Southeastern United States is also thought to be facilitated by a unique ballooning technique. This technique refers to the spiders being able to release silk strands that catch air currents which allows them to travel long distances - even up to 100 miles. Since hitchhiking to the states, the species has rapidly multiplied and reports indicate their presence in other states including South Carolina, North Carolina, Tennessee, Alabama, Maryland, Oklahoma, and West Virginia. So, can New Jersey residents expect a Joro spider invasion any time soon?The unpredictable nature of their movements raises concerns about potential expansion, with New Jersey being a potential future destination for the invasive arachnid.
What Does a Joro Spider Look Like?
The giant Joro Spider size and distinctive (somewhat creepy) features set it apart in the arachnid world. The Joro spider has gained notoriety because of its large size - and this is particularly evident in the females of the species. Female Joro spiders usually exhibit a robust abdomen and elongated legs, with measurements that range from 0.66 to 0.98 inches. While males are comparatively smaller, measuring around 0.27 to 0.39 inches.To make matters more intimidating, there have been some instances in Georgia, where female Joro spiders boasted leg spans of 3 to 4 inches. It is their substantial size and daunting appearance that contributes to their imposing presence.The coloration of the Joro spider is a striking aspect of its visual identity. Females are made up of deep blue and yellow bands on their legs, creating a vibrant and overwhelming contrast. While the abdomen exhibits asymmetrical patterns blending red, yellow, and black hues. In contrast to their female counterparts, the males are characterized by a plain brown body.As an intimidating looking creature, many are fearful to come into contact with Joro spiders. But, are they dangerous to humans?
Is a Joro spider poisonous?
You are probably wondering whether the Joro spider is poisonous or not - and we have good news for you! Despite its imposing size and striking appearance, the Joro Spider actually poses minimal threat to humans. While it is vital to acknowledge that all spiders are venomous, their venom is generally not potent enough to cause significant harm to humans. In fact, the Joro spider's venom is comparable to that of a small bee sting, because its primary function is to simply subdue its prey - which are typically insects.These spiders are also not aggressive toward humans and are actually known to have quite a timid nature. Studies have actually shown that these creatures exhibit quite a unique response to disturbances, freezing on the spot for an extended period of time - sometimes up to 1 hour. This behavior highlights their timidness as they automatically try to avoid confrontation. While these large arachnids do have fangs, they are not typically strong enough to puncture human skin. Essentially, unless a person is specifically allergic to Joro spider venom, there is generally no cause for concern regarding a Joro spider bite.It is essential to dispel misconceptions and fears surrounding the Joro spider, emphasizing that their presence is more of a nuisance than a genuine threat. As an outdoor species, Joro spiders are not inclined to invade homes or actively engage with humans. Understanding their limited danger to humans allows for a more informed and measured response to their increasing presence in various regions in the United States.
Does the Joro Spider Fly?
The thought of a spider as intimidating as the Joro spider being able to fly would send a shiver down anyone’s spine - and many people have heard whispers about this. But, are the rumours true? Are you going to spot a Joro spider flying?
One of the intriguing aspects of the Joro Spideris its ability to engage in a form of aerial movement that can be described as "flying." As touched upon previously, this phenomenon is known as ballooning and plays a vital role in the spider's dispersal and rapid spread across different regions. But what exactly is ballooning? This movement refers to the action of releasing silk strands into the air. These strands then catch air currents which allows the spider to be carried over considerable distances. The spiders use this technique for various purposes, including finding new habitats, seeking mates, and escaping unfavorable conditions. This behavior is particularly noteworthy in the context of the Joro spider's spread, as they've been seen traveling up to 100 miles using this method.So, you may not spot a Joro Spider flying - but you may spot a Joro spider parachute!
It is important to note that the ballooning technique is not exclusive to Joro spiders but their proficiency in using it to their advantage has played a significant role in their adaptability in diverse environments. And as stated previously, this behavior is thought to contribute to their unexpected appearances in regions far from their native territories.
What does the Joro spider eat?
Understanding the dietary preferences of Joro spiders provides insights into their ecological role and their impact on local insect populations.Joro spiders are weave orbs and construct elaborate webs that have circular patterns. These webs serve as effective traps for flying insects. The primary diet of Joro spiders consists of a variety of flying insects that become caught in their silk webs.Essentially, these spiders are indiscriminate when it comes to food, capturing a wide variety of insects that come into contact with their intricate webs. While their specific prey may vary based on environmental factors and seasonal changes, Joro spiders are known to consume insects such as flies, mosquitoes, moths, and other small flying creatures - making them adaptable to most environments. But it is important to remember that In their role as insect predators, Joro spiders actually contribute to natural pest control. By keeping populations of flying insects down they play a role in maintaining ecological balance. But of course, their invasive nature and potential impact on native spider populations raises questions about the broader ecological consequences of their presence in new environments.
Will Joro spiders invade my property?
As the Joro Spider continues its invasive spread, residents in New Jersey may find these arachnids making appearances on their properties. Understanding potential habitats favored by these creepy crawlies and knowing what to do when encountering them can help mitigate concerns. This is where Joro Spider control comes in. Joro spiders are adaptable in their choice of habitats and environment, and they are commonly found in areas where their orb webs can be built. Outdoor spaces with structures like trees, bushes, and man-made structures provide perfect locations for them to spin their webs. Their preference for areas on the edge of woods and close to homes makes suburban and urban environments susceptible to their presence.
What to Do if You See a Joro Spider:
Remain Calm: Despite their intimidating appearance, Joro spiders are generally not harmful to humans. Remain calm if you come across one.
Avoid Disturbance: Joro spiders exhibit a timid nature, and their response to disturbances is to freeze. Avoid unnecessary contact to prevent stress to the spider.
Outdoor Dwellers: Joro spiders are primarily outdoor creatures and are not inclined to enter homes. If found on your property, they are likely to stay outdoors.
