Thamnophis marcianus bovalli
Thamnophis marcianus marcianus
Thamnophis marcianus praeocularis
Thamnophis marcianus bovalli – from south-west Nicaragua into northern Costa Rica.
Thamnophis marcianus marcianus – from south-western Kansas westward to south-eastern California and southward through the north and east of Mexico into northern Veracruz. In Tehuantepec (Oaxaca, Mexico) lives an isolated population.
Thamnophis marcianus praeocularis – from the Yucatan Peninsula, through Belize and north-eastern Guatemala into western Honduras.
Prefers treeless, (semi-) dry grasslands and desert areas.
However, they usually do not live far from water such as canals, lakes, streams, rivers and springs.
In southern Texas, they are also found in gardens; they are not really afraid of the people there.
In the neo-tropical parts it occurs mainly in the relatively dense-vegetated shores from lakes.
Amphibians, fish, earthworms, lizards, rodents, and sometimes also snakes.
Between June and September the young are born, depending on the height where the animals live.
A litter consists of 5 to 30 young which are 15 to 20 cm long.
In southern Texas and Mexico they sometimes produce two litters per year.
In Arizona and southern Texas, the young are already born middle May.
Adult snakes of this species are best kept in a large terrarium. Place a not too large water bowl (if the snakes can lie in it, is big enough) so the terrarium remains reasonably dry. As usual, there should be some climbing branches and some shelters placed.in the terrarium
This species seems to be easy to care for and usually it does not mind being handled.
Brumating stimulates breeding, but if you do not know what area the animals (or the parents) come from, you need to be careful. Temperatures of 4 degrees Celsius sometimes seem to cause neurological problems. Keep a safe limit of about 10 degrees Celsius for about six weeks.
Occasionally cannibalism seems to appear.
These snakes like to burrow, so provide the terrarium with a thick bottom layer.
Average length of about 70 to 80 cm, with a maximum of about 100 cm.
Occurs at heights between 0 and 1600 meters.
Is usually active during the day, but in the southern habitats sometimes at night.
Brumates for three to four months in the higher parts of its range, but in the lower, southern parts only a few weeks.
