Moth Caterpillars. by Jeffrey S. Pippen | Back to Jeff's Butterfly Page | Back to Jeff's Misc. Thanks to many folks who have helped me ID some of the creatures on this page, including Anurag Agrawal, John & Jane Balaban, Cheri Cameron, Pat Coin, Steve Hall, Sean Hitch, Josh Rose, and Steve & Dean.
Mad as a March hare. To be as mad as a March hare is an English idiomatic phrase derived from the observed antics, said to occur only in the March breeding season of the Hare, genus Lepus.
Mad is often used in informal speech to describe behaviour that is wild or unpredictable, or a person who is behaving in such a way. Care should be taken with this word and with all its synonyms, since many of them can cause great offence.
