This depends on what country your in, In Australia, Yes, you do need a License, in Great Britain, Yes, the Ultralights/Microlights there are listed under their national register and therefore you need a license. In the United States, A true single seat ultralight requires no license to fly (assuming it meets the requirements of Part 103 for an ultralight aircraft).

Ultra light
The worlds lightest airplane is I believe the ultralight. Now ultralight aircrafts come in many different shapes and sizes but they are the "Family" of the lightest planes. To see what they look like, go to google.com and type in pictures of ultralight planes.
Microlights, or ultralights in some countries, are small, fixed wing one or two seat aircraft. A person may or may not need special permits to fly an ultralight. Each country sets its own regulations. In the US one would check with the FAA for rules and regulations for ultralight (microlight) flying.
