The milk snake or milksnake, is a species of kingsnake; there were once up to 24 subspecies recognized, however fewer are officially recognized today. Lampropeltis elapsoides, the scarlet kingsnake, was formerly classified as a 25th subspecies, but is now recognized as a distinct species. The previously delineated subspecies have strikingly different appearances, and many of them have their own common names. Morphological and genetic data suggest that this species could be split into several separate species, and it has been by several authorities. Lampropeltis gentilis, Lampropeltis annulata, Lampropeltis abnorma, Lampropeltis polyzona, and Lampropeltis micropholis have been elevated to the species level. Milksnakes are not venomous.
📌 Geographic range
Milk snakes can be found from the southeastern extreme of Ontario, Canada, into southeastern Maine and all the states of the Eastern Seaboard of the United States of America, south to Florida, Alabama, Mississippi; in the midwest, from central Minnesota to Colorado, Nebraska, and the Dakotas; they are found in the foothills of the Appalachian Mountains; and in Georgia, Tennessee, Kentucky, Arkansas, Missouri, Kansas, Oklahoma, Texas and Louisiana. There are further subspecies found in nearly all of Mexico, from the state of Sonora east to the Gulf coast of Tamaulipas and throughout the rest of south and central Mexico; all through Central America and into Colombia and Ecuador.
📌 Behavior
Milk snakes are mostly nocturnal, especially during summer months. They are primarily terrestrial and attempt to blend in with ground litter. However, they are able to climb and swim. These snakes tend to be secretive and remain hidden. When threatened, a milk snake will usually first try to escape. If cornered or harassed, it may vibrate its tail and strike energetically, though they are non-venomous, have only tiny teeth and their tails lack a rattle. Unless frightened, milk snakes move slowly. They are often fairly docile.
📌 Reproduction
Milk snakes are oviparous, laying an average of about 10 eggs per clutch, although that number may vary by region. to late June. In June and July, the female lays three to 24 eggs beneath logs, boards, rocks, and rotting vegetation.
Milk snakes typically live around 12 years, or up to 21 years in captivity. They reach maturity within three or four years.
📌 Conservation status
The milk snake is listed as of least concern by the IUCN (a wildlife conservation union), but in some areas, they may face significant pressure due to pet-trade collection. Because of this species' attractiveness in the pet trade, many subspecies are now being bred in captivity for sale.
