Character Abstract
Identification Comments:
Subspecies Comments:
Food Habits:This species primarily eats ants but also consumes many non-ant insects and arthropods including grasshoppers, beetles, spiders, and true bugs (Jones and Lovich 2009).
Phenology Comments:
Reproduction Comments:Live bearing; 3-15 young, July-September (Stebbins 2003). Sexually mature in 2 or more years (Hammerson 1982, Nussbaum et al. 1983).
Migration Mobility:
Habitat Comments:The pygmy short-horned lizard's habitat ranges from semiarid plains of sagebrush and bunch grass, to pinyon-juniper woodlands, to pine forests in high mountains. It is usually found in open, shrubby, or openly wooded areas with sparse vegetation at ground level. The soil may vary from rocky to sandy to hardpan, but pockets of fine loose soil or sand are typically present for burrowing. Occurs from 300 to 2,200 m.
Ecology comments:Population densities vary greatly, ranging from less than two up to 15 individuals/hectare (Jones and Lovich 2009). Though adapted to living in a colder environment than other species of horned lizard, the pygmy short-horned lizard is inactive during cold weather or extended periods of heat. When inactive it burrows into soil or occupies rodent burrows. This species is live bearing (Stebbins 2003).
