This jumping spider lives in warm lands. It lives in Mexico and Central America.
Most spiders eat other bugs. This spider is different. It eats parts of plants for food. It eats tiny nubs on leaves.
These nubs have fat and protein. They grow on special trees. The spider stays away from ants on the tree.
Male spiders have red bodies. Female spiders are light brown. They have green markings too.
These spiders can live in large groups. They can breed all year long.
The Bagheera kiplingi is a jumping spider.
It lives in Mexico and Central America. Most spiders eat other bugs. This spider is different. It is mostly herbivorous. That means it eats plants for food.
These spiders live on acacia trees. They eat tiny nubs on the leaves. These nubs are called Beltian bodies. They are full of fat and protein. Ants also live on these trees. The ants try to guard the nubs. The spiders must stay away from the ants.
Most of their food comes from these plant nubs. They also eat nectar. Sometimes they eat ant larvae. The spiders look different based on their sex. This is called sexual dimorphism.
Males have amber legs and red bodies. Females have light yellow legs. They have light brown bodies with green marks.
In Mexico, these spiders live on many acacia trees. In Costa Rica, they live on fewer trees. They can live in large groups. Sometimes, hundreds of spiders live on one tree. There are more females than males. They can breed all year long.
The Bagheera kiplingi is a very special kind of jumping spider.
Most spiders hunt and eat other small insects. However, this spider is mostly herbivorous. This means it gets most of its food from plants. It is the only known omnivorous spider with such a plant-heavy diet. You can find these spiders in Central America. They live in places like Mexico, Costa Rica, and Guatemala.
These spiders live on acacia trees, specifically in the genus Vachellia. They look for tiny nubs on the leaf tips called Beltian bodies. These nubs are very important because they are rich in protein and fat. The tree makes these nubs as part of a partnership with certain ants. The spiders must be careful to avoid the ants that guard the food. While Beltian bodies make up over 90% of their diet, they also eat nectar. Sometimes they even steal ant larvae or eat other spiders.
People have studied these spiders for a long time. George and Elizabeth Peckham first named the genus in 1896. They named it after Bagheera, the black panther from The Jungle Book. They also named the species to honor the author, Rudyard Kipling. Scientists only described the male spider in 1896. It took another 100 years for Wayne Maddison to describe the female. This shows how much work goes into learning about nature.
Male and female spiders look very different from each other. This difference is called sexual dimorphism.
Males have amber legs and a dark, greenish cephalothorax. Their slender red abdomen has green lines across it. Females have sturdier amber front legs and slender light yellow legs. Their large abdomen is light brown with dark brown and green markings. In Mexico, they live on more than 50% of Vachellia collinsii trees. In Costa Rica, they live on less than 5% of acacia trees.
These spiders have interesting ways of living together. Most spiders like to live alone, but these can live in large groups. In Mexico, hundreds of spiders have been found on a single acacia tree. There are usually more than twice as many females as males in these groups. They can breed throughout the entire year. Some scientists believe they are quasisocial because females guard their eggs and babies. This way of living helps them thrive in their leafy homes.
Bagheera kiplingi is a unique species of jumping spider found in Central America. This region includes countries like Mexico, Costa Rica, and Guatemala. Most spiders are predators that hunt other animals for food. However, Bagheera kiplingi is notable for its highly herbivorous diet. It is the only known species of omnivorous spider with such a plant-heavy diet. This means it eats both plants and animals, but it relies mostly on vegetation. Scientists use isotopic signatures in spider tissues to prove this diet. These signatures show that most of their food comes from plants rather than meat.
The spider survives by exploiting a specific relationship between plants and ants. It lives on acacia trees, specifically those in the genus Vachellia. These trees produce small nubs at the tips of their leaves called Beltian bodies. These nubs are specialized structures that are rich in protein and fat. The acacia tree creates these bodies as part of a mutualism with certain ant species. This is a symbiotic relationship where both the tree and the ants benefit. The spiders eat these nubs, which make up over 90% of their diet. They must actively avoid the ants that guard these food sources.
While Beltian bodies are their main food, Bagheera kiplingi is still technically an omnivore. They also consume nectar from the trees to get energy. Occasionally, they will steal ant larvae from worker ants as they pass by. They may even engage in cannibalism by eating other spiders of their own species. This behavior is more common during the dry season. Interestingly, scientists have not yet researched the exact mechanism they use to process these foods. Most spiders use digestive enzymes to liquefy prey before sucking it up. It is still unknown how these spiders metabolize the solid Beltian bodies.
This species shows clear sexual dimorphism, meaning males and females look very different. The male has amber legs and a dark cephalothorax, which is the head and mid-section. The upper region of his cephalothorax is greenish near the front. He also has a slender reddish abdomen with green transversal lines. The female has a different appearance and build. Her front legs are amber and sturdier than her other slender, light yellow legs. Her cephalothorax is reddish-brown with a black top region. Her abdomen is quite large, light brown, and features dark brown and greenish markings.
History shows that it took a long time to fully understand this species. George and Elizabeth Peckham first named the genus in 1896. They chose the name Bagheera after the black panther in Rudyard Kipling's The Jungle Book. They also named the species to honor Kipling himself. Other jumping spider genera, such as Akela, Messua, and Nagaina, also use names from Kipling's characters. The Peckhams only described the male spider in 1896. It took another 100 years for Wayne Maddison to describe the female in 1996.
The diet and population of these spiders change based on their environment. In Mexico, they inhabit more than 50% of Vachellia collinsii trees. In these areas, they eat an almost exclusively herbivorous diet. However, in Costa Rica, the population is much smaller. They inhabit less than 5% of the available acacia trees there. In Costa Rica, their diet is less herbivorous than the spiders in Mexico. This shows how much the local environment affects how a species lives and eats.
Bagheera kiplingi also has unique social behaviors compared to other spiders. Most jumping spiders are solitary and live alone. However, populations of several hundred specimens have been found on single acacias in Mexico. In these large groups, there are more than twice as many females as males. These spiders appear to breed throughout the entire year. Observations of adult females guarding egg clutches suggest they are quasisocial. This means they show some level of social organization, such as caring for the young.
