Hello all! My son and I keep quite a number of creatures from millipedes and mantids to frogs and snakes. This weekend we were at a reptile show looking for any new neat insects that might be available. Well, in addition to a beautiful Flower Mantis, we can home with a Horned Lizard. The guy said they were easy to care for so I didn't really hesitate to add this cute little guy to our menagerie. Now, in my defense I generally don't buy anything without first researching the care requirements. I was very dismayed to learn about the strict eating habits of HL's. Which leads me to my question. Can they only be fed harvester ants? Or can other species of ants supply the formic acid needed in their diet? Thanks!
