Frog Marriage Tradition in India
![]() |
In general, marriage brings companionship and support to two individuals. But have you ever heard of a marriage believed to bring rainfall as well? Yes, it’s true, but the wedding is not between humans. It is a ceremonial marriage between a male and a female frog, performed by people.
For centuries, many communities across India have conducted frog marriages during summer or at the beginning of the monsoon, hoping to invite rain. This tradition is known by different names in different regions. In Assam, it is called Bhekuli Biya; in Tripura, Banger Biye; and in the southern states of India, it is known as Manduka Parinayam or Kappala Pelli.
How Is a Frog Marriage Performed?
For the frog marriage, a male and a female frog are collected from the nearby ponds or water bodies and decorated like a bride and groom. During the wedding, sindoor is applied to the bride’s forehead. In some regions, the male frog symbolically ties a sacred yellow thread (mangalsutra) around the female frog’s neck with the help of the people conducting the ceremony.
After the marriage, the newlywed frog couple is taken through the village in a festive procession. Villagers shower the frogs with turmeric, sindoor, flowers, and water. In some southern states, such as Andhra Pradesh, people also pour water on themselves during the procession as part of the celebration.
The Cultural Beliefs Behind the Frog Marriage:
The beliefs behind this tradition vary from region to region.
One of the earliest references comes from the Rig Veda. A hymn composed by Sage Vasishta describes green and spotted frogs celebrating the arrival of rain by croaking one after another. Many people interpret this hymn as a symbolic expression of frogs showing gratitude to the rain god Parjanya.
In some regions, people believe these frogs belong to the frog species of Kanvaka, Kaimaka, and Taduri, which are generally referred to as wild frogs. These frogs mostly live in temporary, rainfall-dependent water bodies or remain hidden in mud or underground to avoid drying out during the hot summer months. They wait for the rains before emerging to search for food and reproduce. Since these frogs depend entirely on seasonal rainfall for their survival, people believe they express deep gratitude to the rain god for bringing back water, food, and fertility.
India has long been an agriculture-based country, and rainfall determines the livelihood of millions of farmers. Since these frogs are believed to be the beloved devotees of the rain god, many people believe that honouring the frogs is equal to honouring the rain god. As a result, frog marriages are performed during times of drought or prolonged periods without rainfall.
There is also a popular folk tale from Assam behind this tradition.
Once upon a time, when there were no rains, farmers asked the clouds, “Why are you not raining?” Then the clouds replied, “ If the frogs do not croak, there will not be rain.”
This folk tale depicts the close relationship between the rain god Varuna Dev and his beloved devotees, the frogs.
In 2019, people in Madhya Pradesh performed the marriage of two clay frogs instead of live frogs to preserve the tradition without disturbing the animals.
Although there is no scientific evidence that frog marriages bring rainfall, the tradition beautifully reflects how Indian communities respect nature and express gratitude toward it.
The Science Behind Frogs' Croaking Before Rain:
The ancestors of modern frogs first evolved in water and later adapted to life on land. Frogs breathe through their lungs, skin, and the lining of their mouth. Because their skin is highly permeable, they are extremely sensitive to even small changes in air pressure, humidity, temperature, and distant thunder.
As humidity increases and air pressure falls before rainfall, many terrestrial and tree-dwelling frogs that spend dry periods hidden under underground or in moist places detect these environmental changes. They emerge in search of food and begin croaking to attract mates.
Croaking is mainly the call of male frogs. Each species produces its own unique call, allowing females to identify males of the same species even when many different frogs are calling together after rain. Warm temperatures and high humidity also help the sound travel farther, making it easier for frogs to communicate during the breeding season.
For many wild frog species, the rainy season is the ideal time to breed. Temporary pools formed by rain provide safe places for reproduction, especially for species that avoid permanent water bodies where predators such as fish are common. Frog eggs and tadpoles have soft, jelly-like coverings that must remain moist. Without enough moisture or water, they can quickly dry out and die.
Frogs: Nature Rain Forecasters
Frogs do not cause rainfall. Instead, their remarkable ability to sense changes in humidity, air pressure, and other weather conditions allows them to detect approaching rain.
This close connection between frog activity and the rainfall of the monsoon likely inspired traditions such as frog marriages that continue in many parts of India. While the ceremony may not bring rain in a scientific sense, it reflects generations of careful observation of nature and a deep cultural bond between people, frogs, and the life-giving monsoon.
