Danainae is a subfamily of butterflies. It belongs in the family Nymphalidae. There are over 200 species.[1] They are commonly known as Milkweed Butterflies or danaids.

These butterflies are common in tropical places all over the world.[1]

One of the most famous butterflies, the Monarch (Danaus plexippus), belongs in this subfamily.[1]

All males in this subfamily have hair pencils (a body part at the end of the abdomen that can be pulled back inside the body) and androconia (spots on the bottom wings that release scents to attract females). The male is attracted to certain flowers (Heliotropium, Eupatorium, Senecio, and Crotalaria). The male feeds at these flowers. These plants have a chemical called alkaloid lycopsamine. After the chemical is in the male's body, the alkaloid lycopsamines change into dihydropyrrolizine. This chemical is released by the androconia. The male raises his abdomen and puts his hair pencils into the androconia. After the hair pencils have the chemical on them, the male will use them during courtship.[1]
