Many moths do not feed as adults but rely on energy stored from their days as caterpillars. This is one example. Moths and butterflies feed on liquid sucked up through a "straw" or proboscis. In this Tussock moth, you can see the proboscis is split in two - the mouthparts are present but not functional.
