Stick Insect Helps Scientists Study How Animals Move

Stick insects, which look like walking twigs, are popular as pets and research subjects because they’re easy to keep, can’t fly away, and move at a pace that allows observation and study.  “I think they’re really, really sweet insects,” said Chris J. Dallmann, a researcher at Bielefeld University in Germany, who just completed a scientific report on the biomechanics of a stick insect’s six legs and what are, loosely speaking, its knee and hip joints.
