Moth antennae are pointed at the ends, not knobbed like a butterfly's. Antenna Butterflies have a long, hollow tube called a proboscis which they use to sip nectar. When the proboscis is not being used, it stays coiled. These changes are known as metamorphosis. The adult monarch feeds on the nectar of flowers, its favorite being the milkweed.
Monarchs are the only insects that fly south for the winter.
Some travel almost 2,000 miles before reaching their destination. Anatomy A typical insect has three parts to its body and three pairs of legs. Insects do not have backbones, they are supported by a sort of skeleton on the outside of their bodies. They have adapted for chewing, sucking, piercing and sucking and lapping. There are so many types of flies in the world that scientists have trouble keeping track of them.
