Do stick insects bite humans

Nearly all stick insect species are harmless and are not toxic. None cat actually deliver a bite as all stick insects have evolved to nibble the edges of leaves, and none have stingers. However, the Two-Striped Walking Stick (Anisomorpha buprestoides) is said to have a defensive spray that can cause temporary blindness if caught in the eyes. Other stick insect species can also spray but have no harmful effects.
