We use monarchs, changing an individual’s DNA in its chrysalis. In the chrysalis, it’s rebuilding itself from scratch anyway. This gives you a large bug with any number of useful differences—different sensors, different coloration, different diet, different appendages, different life cycle. We can design it to match your specification, and we can create as many as you wish. We have used this process to create cave explorers, giving them the ability to swim and to fly while carrying a tiny camera. We have made spies for the CIA. We have made guides for hikers. We have made wildlife monitors, and monitors for wildfires and overall wilderness health. Their many uses are limited only by your imagination and the raw biological materials.
