Neon green “happy-face” spider discovered during ant research expedition

by

A newly discovered spider in the Himalayas is gaining popularity online because of a distinctive marking on its back – it looks like a smiling face! The marking even appears to glow.

Scientists have discovered a new spider species, nicknamed the “Himalayan happy-face spider” (Theridion himalayana), in the high-elevation forests of Uttarakhand, a region in northern India. The discovery was published in the journal Evolutionary Systematics.

Researchers stumbled upon the spider while studying ants. They were surprised to find it looked very similar to the well-known Hawaiian happy-face spider, which was previously thought to live only in Hawaii.

Scientists have identified a happy-face spider species for the first time outside of the Pacific area.

Scientists say the spider discovery came as a “jackpot”

Devi Priyadarshini, a researcher involved in the study, explained that she quickly identified the spider when samples from high in the Himalayas were submitted for analysis.

Priyadarshini explained that she was stunned when she saw the spider, as it was the same species she’d studied during her master’s program. She immediately realized they had found something significant because of how clearly it matched her previous observations.

Ashirwad Tripathy, her co-author, said they named the species “himalayana” to recognize the rich variety of life found in the Himalayan mountains.

Tripathy explained that they both wanted to show their respect for the majestic Himalayas, which not only protect our country but are also home to a wide variety of plant and animal life.

Researchers studying spiders in three areas of the Himalayas – Makku, Tala, and Mandal – found 32 different color patterns, called morphs, within the species. Genetic testing showed the Himalayan spider is about 8.5% different from the Hawaiian happy-face spider, proving it developed independently in Asia.

Scientists noticed another surprising similarity between the spiders in Uttarakhand and those in Hawaii: both groups were often found on ginger plants. This is notable because ginger is considered an invasive plant in Hawaii.

Priyadarshini wondered how the spiders specifically selected the ginger plant as an invasive species, noting that this finding creates opportunities for further study.

Even though this spider has unique markings, scientists are still unsure why it has a pattern that looks like a smile.

These markings clearly improve their chances of survival in the wild, but researchers are still trying to understand why they develop these specific patterns on their backs and what purpose those patterns serve throughout their lives, according to Priyadarshini.

Scientists recently discovered a huge new dinosaur species in Thailand. They believe this long-necked dinosaur lived over 200 million years ago, making it one of the oldest of its kind ever found in the area.
