Diet and Decline
About 70% of the Texas horned lizard's diet is made up of harvester ants, though they supplement these with termites, beetles, and grasshoppers. In recent years, the Texas horned lizard has declined by about 30% of its range, though there is some indication it may be making a comeback. The decline is usually blamed on overuse of pesticides and the spread of nonnative, but highly aggressive and fiercely territorial, red imported fire ants. Both eradicate harvester ant colonies, destroying the horned lizard's principal source of food. The Texas horned lizard is now a protected species, and it is illegal to take, possess, transport or sell them without a special permit.

Famous quotes containing the words diet and/or decline:
“Literary tradition is full of lies about poverty—the jolly beggar, the poor but happy milkmaid, the wholesome diet of porridge, etc.”
—Mason Cooley (b. 1927)
“Our achievements speak for themselves. What we have to keep track of are our failures, discouragements, and doubts. We tend to forget the past difficulties, the many false starts, and the painful groping. We see our past achievements as the end result of a clean forward thrust, and our present difficulties as signs of decline and decay.”
—Eric Hoffer (1902–1983)
