New discovery reveals chimpanzees in Uganda use flying insects to tend their wounds
Kayla Kolff, Osnabrück University
Animals respond to injury in many ways. So far, evidence for animals tending wounds with biologically active materials is rare. Yet, a recent study of an orangutan treating a wound with a medicinal plant provides a promising lead.
Chimpanzees, for example, are known to lick their wounds and sometimes press leaves onto them, but these behaviours are still only partly understood. We still do not know how often these actions occur, whether they are deliberate, or how inventive chimpanzees can be when responding to wounds.
Recent field observations in Uganda, east Africa, are now revealing intriguing insights into how these animals cope with wounds.
As a primatologist, I am fascinated by the cognitive and social lives of chimpanzees, and by what sickness-related behaviours can reveal about the evolutionary origins of care and empathy in people. Chimpanzees are among our closest living relatives, and we can learn so much about ourselves through understanding them.
In our research based in Kibale National Park, Uganda, chimpanzees have been seen applying insects to their own open wounds on five occasions, and in one case to another individual.
Behaviours like insect application show that chimpanzees are not passive when wounded. They experiment with their environment, sometimes alone and occasionally with others. While we should not jump too quickly to call this “medicine”, it does show that they are capable of responding to wounds in inventive and sometimes cooperative ways.
Each new insight adds reveals more about chimpanzees, offering glimpses into the shared evolutionary roots of our own responses to injury and caregiving instincts.
First catch your insect
We saw the insect applications by chance while observing and recording their behaviour in the forest, but paid special attention to chimpanzees with open wounds.Insect application by subadult Damien.
In all observed cases, the sequence of actions seemed deliberate. A chimpanzee caught an unidentified flying insect, immobilised it between lips or fingers, and pressed it directly onto an open wound. The same insect was sometimes reapplied several times, occasionally after being held briefly in the mouth, before being discarded. Other chimpanzees occasionally watched the process closely, seemingly with curiosity.
Most often the behaviour was directed at the chimpanzee’s own open wound. However, in one rare instance, an adolescent female applied an insect to her brother’s wound. A study on the same community has shown that chimpanzees also dab the wounds of unrelated members with leaves, prompting the question of whether insect application of these chimpanzees, too, might extend beyond family members. Acts of care, whether directed towards family or others, can reveal the early foundations of empathy and cooperation.
The observed sequence closely resembles the insect applications seen in Central chimpanzees in Gabon, Africa. The similarity suggests that insect application may represent a more widespread behaviour performed by chimpanzee than previously recognised.
The finding from Kibale National Park broadens our view of how chimpanzees respond to wounds. Rather than leaving wounds unattended, they sometimes act in ways that appear deliberate and targeted.
Chimpanzee first aid?
The obvious question is what function this behaviour might serve. We know that chimpanzees deliberately use plants in ways that can improve their health: swallowing rough leaves that help expel intestinal parasites or chewing bitter shoots with possible anti-parasitic effects.
Insects, however, are a different matter. Pressing insects onto wounds has not yet been shown to speed up healing or reduce infection. Many insects do produce antimicrobial or anti-inflammatory substances, so the possibility is there, but scientific testing is still needed.
For now, what we can say is that the behaviour appears to be targeted, patterned and deliberate. The single case of an insect being applied to another individual is especially intriguing. Chimpanzees are highly social animals, but active helping is relatively rare. Alongside well-known behaviours such as grooming, food sharing, and support in fights, applying an insect to a sibling’s wound hints at another form of care, one that goes beyond maintaining relationships to possibly improving the other’s physical condition.
Big questions
This behaviour leaves us with some big questions. If insect application proves medicative, it could explain why chimpanzees do it. This in turn raises the question of how the behaviour arises in the first place: do chimpanzees learn it by observing others, or does it emerge more spontaneously? From there arises the question of selectivity – are they choosing particular flying insects, and if so, do others in the group learn to select the same ones?
In human traditional medicine (entomotherapy), flying insects such as honeybees and blowflies are valued for their antimicrobial or anti-inflammatory effects. Whether the insects applied by chimpanzees provide similar benefits is still to be investigated.
Finally, if chimpanzees are indeed applying insects with medicinal value and sometimes placing them on the wounds of others, this could represent active helping and even prosocial behaviour. (The term is used to describe behaviours that benefit others rather than the individual performing them.)
Watching chimpanzees in Kibale National Park immobilise a flying insect and gently press it onto an open wound reminds us how much there is still to learn about their abilities. It also adds to the growing evidence that the roots of care and healing behaviours extend much further back in evolutionary time.
If insect applications prove to be medicinal, this adds to the importance of safeguarding chimpanzees and their habitats. In turn, these habitats protect the insects that can contribute to chimpanzee well-being.![]()

Can animals give birth to twins?
We are faculty members at Mississippi State University College of Veterinary Medicine. We’ve been present for the births of many puppies and kittens over the years – and the animal moms almost always deliver multiples.
But are all those animal siblings who share the same birthday twins?
Twins are two peas in a pod
Twins are defined as two offspring from the same pregnancy.
They can be identical, which means a single sperm fertilized a single egg that divided into two separate cells that went on to develop into two identical babies. They share the same DNA, and that’s why the two twins are essentially indistinguishable from each other.
Twins can also be fraternal. That’s the outcome when two separate eggs are fertilized individually at the same time. Each twin has its own set of genes from the mother and the father. One can be male and one can be female. Fraternal twins are basically as similar as any set of siblings.
Approximately 3% of human pregnancies in the United States produce twins. Most of those are fraternal – approximately one out of every three pairs of twins is identical.
Multiple babies from one animal mom
Each kind of animal has its own standard number of offspring per birth. People tend to know the most about domesticated species that are kept as pets or farm animals.
One study that surveyed the size of over 10,000 litters among purebred dogs found that the average number of puppies varied by the size of the dog breed. Miniature breed dogs – like chihuahuas and toy poodles, generally weighing less than 10 pounds (4.5 kilograms) – averaged 3.5 puppies per litter. Giant breed dogs – like mastiffs and Great Danes, typically over 100 pounds (45 kilograms) – averaged more than seven puppies per litter.
When a litter of dogs, for instance, consists of only two offspring, people tend to refer to the two puppies as twins. Twins are the most common pregnancy outcome in goats, though mom goats can give birth to a single-born kid or larger litters, too. Sheep frequently have twins, but single-born lambs are more common.
Horses, which are pregnant for 11 to 12 months, and cows, which are pregnant for nine to 10 months, tend to have just one foal or calf at a time – but twins may occur. Veterinarians and ranchers have long believed that it would be financially beneficial to encourage the conception of twins in dairy and beef cattle. Basically the farmer would get two calves for the price of one pregnancy.
But twins in cattle may result in birth complications for the cow and undersized calves with reduced survival rates. Similar risks come with twin pregnancies in horses, which tend to lead to both pregnancy complications that may harm the mare and the birth of weak foals.
DNA holds the answer to what kind of twins
So plenty of animals can give birth to twins. A more complicated question is whether two animal babies born together are identical or fraternal twins.
And reproduction is different in various animals. For instance, nine-banded armadillos normally give birth to identical quadruplets. After a mother armadillo releases an egg and it becomes fertilized, it splits into four separate identical cells that develop into identical pups. Its relative, the seven-banded armadillo, can give birth to anywhere from seven to nine identical pups at one time.
There’s still a lot that scientists aren’t sure about when it comes to twins in other species. Since DNA testing is not commonly performed in animals, no one really knows how often identical twins are born. It’s possible – maybe even likely – that identical twins may have been born in some species without anyone’s ever knowing.

Three year old miracle girl found alive after 11 days in Siberian taiga - thanks to her puppy
and drinking river water in territory roamed by wild bears and wolves. Little Karina made herself a bed in the grasses, which are common to the south-west of Sakha in summer, but they meant that helicopters and drones were useless in searching for her in the bear-infested taiga. Ininitally her family and the rescue teams were distraught when the dog - which has not been named despite its heroic role - returned to the girl's village of Olom in Olyokminsky district. 'Two days before we found Karina her puppy came back home,' said Afanasiy Nikolayev, spokesman for the Sakha Republic
