What serious symptoms can manifest if the urticating hairs of a species like *G. pulchra* enter a person's eyes or are inhaled?

Conjunctivitis or respiratory irritation

While urticating hairs primarily cause localized itching and rashes upon skin contact, their involvement with sensitive mucous membranes can lead to significantly more serious reactions. If these microscopic, barbed structures enter the eyes, they can cause inflammation of the eye lining, medically termed conjunctivitis. Similarly, if the hairs are accidentally inhaled into the respiratory system, they can cause irritation to the airways and lungs. These reactions highlight that the mechanical defense of the hairs poses risks beyond simple skin discomfort, demanding awareness, especially regarding eye protection or handling in well-ventilated areas.
