Do Butterflies Drink Blood?
Well, technically—Yes, they do. Don’t worry! They don’t harm humans or animals like blood-sucking insects.
Butterflies can’t break the skin because they don’t have piercing mouthparts. However, if given the chance, they will sip blood. This behavior, called “mud-puddling,” is mostly observed in male butterflies.
During puddling, they sip water and extract essential nutrients like salts and amino acids that are not readily available from nectar. These nutrients are particularly crucial for male butterflies to ensure the success of their reproductive processes.
What is the Primary Source of Nutrition for Butterflies?
Butterflies primarily derive their nutrition from nectar. Nectar is rich in sugars, providing butterflies with the energy they need for flight, reproduction, and other life functions. These dazzling insects use their long, tube-like structure called a proboscis, similar to a straw, to reach into flowers and sip this energy-rich food.
They get nectar mostly from native flowers like sunflowers, dandelions, snapdragons, asters, and daisies. Besides flower nectar, butterflies also devour sap from different parts of plants, like leaves, bark, stems, and seeds.
In addition to nectar and tree sap, some butterflies also feed on puddle nutrients such as sand, mud, animal feces, dung, carrion, and even blood from the open wounds of animals. This behavior is driven by the lack of specific nutrients in their primary food sources.
Moreover, the diet of butterflies shifts dramatically as they progress from larvae to adulthood. Caterpillars, the larvae, primarily consume plant leaves, which provide the protein necessary for growth. Upon metamorphosis into adults, their mouthparts adapt to a liquid diet, and their nutritional focus shifts to energy-rich sources.

Why Do Butterflies Feed on Blood and Mud Puddles?
The puddling behavior of a Butterfly Drinking Blood is more opportunistic and is beyond their preference. They don’t enjoy these unusual food sources. Rather, they seek out specific nutrients that aren’t available in their primary food source—flower nectar. Although the nectar provides them with plenty of sugars for energy, it is deficient in certain minerals, notably sodium and nitrogenous compounds.
Mud puddles, animal urine, dung, decaying flesh, and blood offer butterflies these crucial nutrients. Sodium is vital for nerve signal transmission, muscle contraction, and other physiological processes. Additionally, male butterflies often require excess sodium and nitrogen, which they pass on to females during mating, enhancing the chances of their offspring’s survival.
Blood, being rich in salt and nutrients, is an especially valuable source. While you’ll never see Butterflies Drinking Blood from living creatures, they will take advantage of any available pools from deceased or wounded animals.

Butterflies that Drink Blood
Some common species of Butterflies that Drink Blood through the behavior of puddling are:
- The Two-tailed Pasha or Foxy Emperor (Charaxes jasius): It is one of the largest butterflies in Europe and is also found in parts of Africa and Asia. This butterfly is known for its fast and powerful flight and is typically seen in sunny areas, particularly where its larval food plants—species of the buckthorn family grow.
- The African Monarch (Danaus chrysippus): Popular as the Plain Tiger, it is widely distributed across Africa and Asia. Its caterpillars feed on various milkweed species, which makes both the caterpillar and the adult butterfly toxic to predators.
- The Purple Emperor (Apatura iris): This butterfly is common across Europe and Asia and is known for the males’ stunning purple-blue sheen. The adult butterflies don’t visit flowers for nectar but are instead attracted to tree sap, rotting fruit, animal droppings, and, sometimes, carrion and blood for their nutrients.
- Yellow Fever Butterfly (Eurema hecabe): Popular as the Large Grass Yellow, it is widespread in Asia and Africa. They are small and primarily yellow in color and are common in open grass and scrub habitats.
- Indian Yellow Nawab (Polyura jalysus): This species is native to parts of India and Southeast Asia. Adult butterflies often feed on tree sap, rotting fruit, and occasionally nectar.
- Common Jester (Symbrenthia lilaea): These butterflies are common in South Asia and Southeast Asia. The caterpillars feed on various plants in the nettle family. Adult Common Jester butterflies typically feed on the nectar of flowers.
- Blue Morpho (Morpho peleides): One of the most famous butterfly species, the Blue Morpho is native to the tropical forests of Latin America. Adults do not typically prefer rotting fruit, tree sap, and even damp or muddy areas, where they gather moisture and minerals.
Key Takeaway
Butterflies drink blood, but not from living humans or animals. Instead, they prefer the blood that has spilled or become stagnant from dead organisms. This blood is full of nutrients and is an excellent source of essential nutrition for butterflies.
