Nectar from flowers
Actually, butterflies don't eat flowers. Caterpillars do. The butterflies use their proboscis to suck the nectar out of the center of the flower.
The long thin tube is a proboscis (snout/mouth) which they use to feed-- butterflies use it to sip nectar or other nutrients, and mosquitoes to obtain either nectar or blood.
Butterflies use almost any flower for nectar if they can get their proboscis into it. Some butterflies don't like nectar and prefer to drink from rotten fruit, puddles, or even feces. Of the butterflies that do prefer nectar, some preferred flower species (in the U.S. anyhow) are milkweed, joe pye weed, butterfly weed, butterfly bush, clovers, and thistle.
Butterflies use their long tongues to get the nectar out of flowers. This is called the proboscis. It is similar to a very long, thin straw and it sucks up the nectar of a flower. The proboscis is curled up into a ball shape when it isn't in use.
the tongue of the butterfly is called a Proboscis.
Butterflies suck nectar through a long and flexible tube called proboscis which projects out from the mouth of the butterfly when it is ready to suck nectar
Butterflies use their long, straw-like mouthparts called proboscis to sip nectar from flowers. They unfurl their proboscis and insert it into the flower to access the sweet liquid inside.
