Description
Family Colubridae
The family Colubridae, which includes the kingsnakes (Lampropeltis spp. ), is the largest, most widespread, and diverse family of snakes , with few physical characteristics universal among all species. The family contains 70 percent of the known species of snakes, with more than 1700 species worldwide (Pough et al. 1998). Although some colubrids are dangerously venomous , most are harmless to humans. [2]
Subfamily Dipsadinae
These snakes are the New World counterparts of the Pareinae and resemble them in appearance and habits. They live in tropical America.
Physical Description
Species Diadophis punctatus occidentalis
A small, thin snake with smooth scales . Gray, blue-gray, blackish, or dark olive dorsal coloring, with a bright orange to reddish underside, lightly speckled with black markings, heavily speckled under the chin. The underside of the tail is a bright reddish orange. A narrow orange band around the neck, 1.5 - 3 scale rows wide.[1]
Size/Age/Growth
8 - 34 inches long (20 - 87cm.) Snakes of this subspecies are adult at around 11 - 18 inches (28 -46 cm.)[1]
Habitat
Prefers moist habitats , including wet meadows, rocky hillsides, gardens, farmland, grassland, chaparral , coniferous forests , mixed woodlands.[1]
Biology
Diet
Eats slender salamanders and other small salamanders, tadpoles , small frogs , small snakes , lizards, worms, slugs, and insects. The mild venom may help to incapacitate prey .[1]
Reproduction
Lays eggs in the summer, sometimes in a communal nest .[1]
Behavior
Secretive - usually found under the cover of rocks, wood , bark , boards and other surface debris , but occasionally seen moving on the surface on cloudy days, at dusk, or at night. When disturbed , coils its tail like a corkscrew, exposing the underside which is usually bright red. It may also smear musk and cloacal contents.[1]

Notes
Name
Status: Accepted Name
. Latest taxonomic
scrutiny: Uetz P.
Many herpetologists no longer
recognize the traditional morphologically-based subspecies
of Diadophis punctatus, pending a thorough molecular study of the whole species. One ongoing study (Feldman and Spicer, 2006, Mol. Ecol. 15:2201-2222) has found all of the D. punctatus subspecies in California (except D. p. regalis) to be indistinguishable. It is likely that D. punctatus is composed of several distinct
lineages
that do not follow the geographic ranges
of the subspecies.[1]
