The kingsnakes and milksnakes of the Lampropeltis genus have been among the most popular snakes in terrariums for many years. Their manageable body size, bright colors and comparatively uncomplicated husbandry requirements make most species of non-venomous snakes suitable for beginners in the terrarium hobby. In the past decade, new studies have led to extensive changes in the taxonomic systematics of the king snakes. This book summarizes the currently valid taxonomy of the entire genus Lampropeltis for the first time and thus pursues the approach of promoting the hitherto reluctant acceptance of the use of the valid nomenclature. The author has kept various species of kingsnakes and milksnakes for around 30 years and provides an insight into his husbandry and breeding methods.
