Key Takeaways:
- Horned lizards primarily feed on ants, but they also consume other small insects as prey.
- Their diet reflects their adaptability to different environments, ranging from oak-pine woodlands to thorn scrub deserts.
- Horned lizards rely on patience rather than stalking their prey and strike when the prey gets too close.
- They have unique defense mechanisms such as flattening themselves out, inflating their bodies, and squirting blood from their eyes when threatened.
- Conservation efforts are crucial to protecting horned lizard habitats and ensuring their survival in the wild.
The Diet of Short-horned Lizards
Short-horned lizards, the most widely distributed of the horned lizards, primarily feed on ants. They are also known to consume other small insects. Unlike some lizards that actively chase their prey, short-horned lizards employ a sit-and-wait strategy, relying on patience to strike out when their prey, such as ants and other small insects, approaches too closely.
This feeding behavior allows short-horned lizards to conserve energy while maximizing their chances of capturing their main food source. By strategically positioning themselves and waiting for the opportune moment, they are able to secure their prey without expending unnecessary energy.
Short-horned lizards are well-adapted to their diet of ants and small insects. They possess specialized adaptations in their mouths and digestive systems that allow them to efficiently capture and digest their prey. Their flattened bodies and camouflaged coloration further aid in their ambush hunting strategy, allowing them to blend seamlessly into their surroundings while lying in wait.

The Ant Specialist: Desert Horned Lizards
Desert horned lizards are known as ant specialists, with a particular affinity for large-bodied harvester ants. These lizards have a specialized sticky tongue that allows them to capture their preferred prey. Alongside ants, desert horned lizards also consume other insects, such as spiders, and even vegetation when necessary. This versatility in their diet enables them to survive in different conditions and ensures a consistent food source.
During drought years when ants might be scarce, desert horned lizards exhibit remarkable adaptations. They limit their growth, reproduction, and above-ground activities to conserve energy. Additionally, they have the ability to bury themselves in the soil, keeping cool and camouflaged in their arid desert habitat.
Desert horned lizards play a vital role in regulating ant populations, especially the harvester ants they specialize in. By consuming these ants, they help maintain balance within the ecosystem and prevent outbreaks of these particular species. This natural pest control service underscores the importance of conserving their habitats and protecting their populations.

Horned Lizard Feeding Behavior and Predators
Horned lizards, including short-horned and desert species, exhibit unique foraging behavior in their search for prey. They can be found in open areas, patiently waiting or actively scanning for unsuspecting ants or other small food items. When the opportunity arises, horned lizards swiftly capture their prey with a quick flick of their tongue and consume it whole.
However, while foraging, horned lizards face the constant threat of predation from various animals in their environment. Predators such as hawks, roadrunners, snakes, coyotes, and even domestic pets pose a significant risk to these lizards while they are foraging for food.
In response to the presence of predators, horned lizards have developed unique defense mechanisms to increase their chances of survival. When threatened, they have the remarkable ability to squirt blood from their eyes, which not only startles predators but also contains chemicals that are believed to deter or distract them. Additionally, horned lizards have the ability to inflate their bodies, making themselves appear larger and more intimidating to potential predators.
