Abstract:
Most North American walkingsticks are harmless, but one species, A. buprestoides, can defend itself by spraying an irritating chemical. We present the first reported case in the medical literature of a chemical conjunctivitis caused by the spray of the two-striped walkingstick. The insect has the ability to direct a spray at a predator's eyes, inducing a self-limited conjunctivitis. Keratitis has been reported in a dog, and this may also be a possible complication in humans. Prudence is dictated in handling this insect, and physicians should be aware of the potential for injury to the eyes.
