Behavioral Ecology

Texas horned lizard - Phrynosoma cornutum





  • 2.5-4 inches total length
  • Found in dry, flat areas w/ little vegetation
  • Active during day
  • Prefers warmer temperatures
  • Feed on ants


Interesting Fact:
  • Horned lizards eat large bodied harvester ants almost exclusively.  Except in North eastern Kansas and a few other isolated areas where there are no harvester ant species.  In these parts of their range, horned lizards appear to subsist on a species of small "acrobat" ants.
