Doda, J&K – July 2025: In a surprising turn of events, researchers have documented the first-ever sighting of the Joro Spider (Trichonephila clavata) in Jammu and Kashmir, raising questions/concerns and revealing the details about the species’ expanding ecological range and adaptability to colder climates.

The sighting occurred in Goha Tehsil, located in the Doda district, at an altitude of over 1,550 meters. The bright-colored spiders were observed building large, intricate webs along a roadside bridge and adjacent vegetation — a setting far removed from their native habitats in East Asia, where the species is typically found in warmer and more humid environments.

The discovery was made by Saqib Masood Salaria, a young researcher from Dev Bhoomi Uttarakhand University, and currently working as a contractual Lecturer, at GHSS Behota, Marmat _ who initially noticed the spiders’ unusual coloration and large web structures during a field visit in October 2024.

The observations were confirmed through the iNaturalist platform, where entomologists identified the spiders as Trichonephila clavata.

Further confirmation came from Dr. Andrew K. Davis, an ecologist at the University of Georgia (USA) and a leading authority on Joro spiders, who validated the species identification based on field images.

Traditionally known to inhabit countries like Japan, China, and Korea, the Joro Spider has only recently begun spreading into new territories, including parts of the southeastern United States. Its appearance in Jammu and Kashmir represents the northernmost known distribution of the species in South Asia.

Despite the cooler temperatures in the region — averaging 15–20°C in October and November — the spiders appeared to thrive.

Field studies suggest that T. clavata may possess physiological adaptations such as a higher heart rate in colder conditions, allowing it to survive and reproduce beyond its usual climatic zone.

“No previous record of Joro spiders exists for Jammu and Kashmir,” Salaria told VoM News. “After comparing with regional spider checklists and seeking expert confirmation, we believe this is the first scientific documentation of the species in this part of India.”

The field team noted that the spiders, particularly females, built large orb webs between bridge railings and roadside vegetation, often within 5–10 meters of motorways. Their presence along areas with moderate vehicular traffic suggests a growing tolerance to human activity.

Consistent with earlier research from Georgia (USA), the spiders displayed a startle-freezing response — remaining motionless for extended periods after disturbances. This behaviour, experts suggest, may contribute to their ability to coexist in semi-urban or human-modified environments.

While the arrival of the Joro spider in Jammu and Kashmir adds to the region’s biodiversity, it also raises concerns about the potential ecological impact of an invasive predator.

Researchers warn that the spiders may disrupt local food chains, outcompete native spiders, and negatively affect populations of pollinating insects such as bees. These risks underscore the need for further investigation into how the species integrates into — or alters — its new environment.

“No spiders were found at higher altitudes where temperatures drop significantly,” Salaria said, indicating that while the species is extending its range, its cold tolerance may still have limits.

Adaptation of Joro Spider

The appearance of T. clavata in colder areas may also reflect broader climate-related shifts in species distribution. “This observation supports existing studies that show invasive species adapting quickly to new environmental pressures — a pattern seen globally as climate zones shift,” said Swati Gupta, co-author of the study.

The findings echo a growing body of research linking biological invasions with climate change and global trade — two powerful forces influencing ecological dynamics across continents.

Researchers emphasize the need for long-term monitoring, public awareness, and ecological assessments to determine the impact of the Joro spider’s presence in the Himalayan foothills.

“Whether this is a one-off introduction or the beginning of a new invasive trend is something only time and careful observation will reveal,” Gupta added.

As science continues to track invasive species and their surprising adaptability, the appearance of the Joro spider in Jammu and Kashmir serves as both a discovery and a warning — that even the remotest regions are not immune to global ecological changes.
