I once saw a technical paper where a research institute was able to pattern a functional antenna on the wings of a bee. The research was based on the fact that, given the right environment, you could train bees to associate any scent to that of honey (co-location). For example, explosives. Once trained, with antennas on their wings and a tiny RFID circuit, hives can be released in a city to seek out explosives. The RFID's can track their location...sort of (low power). Bugnology is coming!
