Moonbat is a pejorative political epithet used in United States politics, referring to liberals, progressives, or leftists.
Its Latin name is Gymnocalycium mihanovichii, and it has several common names such as ruby ball cactus or Hibotan. The moon cactus itself is a mutant that lacks the chlorophyll necessary for a plant to feed itself via the process of photosynthesis, or converting sunlight to energy.This species is, therefore, typically grafted on top of another type of cactus from which it feeds.t is common for people to confuse a moon cactus with a cactus flower. Depending on the type of base cactus chosen, a moon cactus might not grow much taller than 12 inches (30.5 cm). While several kinds of cacti live for up to several decades, the Hibotan has a relatively short life span.
