Vietnamese walking sticks grow to about 10 to 12 cm long and are usually brown as adults, though newborns are lighter tan and they turn green after molting. Males have longer antennae and slimmer bodies, while females have shorter antennae and two small horns on the head. They live 5 to 7 months, molt six times (five for males, six for females), and can reproduce after about three months.

How this page works

This is one bug's fact sheet. The colored box at the top says whether it is dangerous. Sections below cover how to recognize it, whether it is a pest, and how to deal with it. The US map shows which states have records; tap a state to see other bugs there.

Every fact on Bug FAQ comes from a named source (university extension sites, government agencies, GBIF, iNaturalist, Wikipedia). The source is linked next to each section. If we have no source for something, we leave it out.
