General Description:
Longnose snakes
are easy to recognize with their alternating
black and orangish-red saddles that are flecked with cream spots.
The only other snake that might have this coloration is the Western Ground Snake,
and they generally lack the light colored
spots. Another characteristic of Longnose Snakes that is unique among
Idaho colubrids, is their caudal scales that are arranged in a single row (Nussbaum
et al. 1983). Longnose snakes have round
pupils and as their common name suggests, a long pointed snout. The
lower jaw is shorter than the upper jaw (Nussbaum et al. 1983), which adds to
the appearance of a long nose. Longnose snakes have the curious defense
behavior of bleeding from the cloaca.
This does not always occur, and the more frequent response, is to coil their
body and to vibrate their tail.
Longnose Snakes are medium-sized snakes usually less than 70 cm (~27 in.) in total length (the record is 104 cm) (Nussbaum et al. 1983).
Based on information from southwestern populations, it is believed that Longnose Snakes lay 5-8 eggs in the early summer, which hatch in late summer or early fall (Nussbaum et al. 1983), and young resemble adults.
Habitat:
Longnose Snakes
are found in desert lowland areas that have sandy or loose soil and numerous
burrows.
Idaho
Distribution:
In Idaho,
Longnose Snakes can be found in the southwestern desert regions of the state.
They may also occur south of Burley, Idaho. From
northern California, southern Idaho, southeastern Colorado, and southwestern
Kansas, south to central Mexico.
Diet:
Eats lizards and their eggs, small snakes,
small mammals, and sometimes birds (in Idaho, eats primarily lizards and mice).
Ecology:
Hibernates
/aestivates
.
Active from about April to September in northern range. Furtive; abundance indicated
by frequency of remains found in hawks' nests (raptors are common predator.)
Little is known about Northwest ecology or life history.
Reproduction:
Female lays 1 clutch (possibly 2) of 5-8
eggs, from June-August. Eggs hatch in 2-3 mo.
