For starters, the larvae (caterpillars) of monarch butterflies eat ONLY milkweed, this is why the monarch butterfly is dubbed the ‘milkweed butterfly’. The larvae stage is the only stage of the monarch butterfly that feeds on milkweed; there is something in milkweed that allows the caterpillar to grow and keep all of the vitamins needed to transform into a beautiful butterfly. In turn, the adult butterflies consume all sorts of different things including nectar, water and even liquids from some of the fruits we consume. If you are looking to attract monarch butterflies to your backyard, simply plant a few fruit-bearing trees along with plenty of flowers and you should definitely have yourself a back yard full of monarch butterflies. They especially like to drink from mushy slices of banana, oranges and watermelon. There are special butterfly feeders you could buy that are colored like a flower and come with special sugar you mix in water to make food for them to eat.

Now many people do not know exactly how the monarch butterfly food is consumed. Well, a small little pipe, like a straw, which is coiled under its head most of the time is what an adult monarch butterfly uses to suck up all of the nectar from plants. The straw is called a ‘proboscis’. This is the reason that all monarch butterflies generally stick to an all-liquid diet; it is very hard to suck up any solids with a straw like that for your mouth.

It is pretty obvious that if you happen to find yourself a monarch butterfly and are looking for a monarch butterfly food source, you should turn toward the liquids. Monarch butterflies are known for their completely liquid diets, whether they are sampling nectar from all sorts of different flowers, or they are using their long ‘straw’ to drink up water out of shallow ponds, monarch butterflies are usually always looking for things that are liquid to eat.
