  We present fluid dynamics videos of the flight of some of the smallest
insects including the jewel wasp, \textit{Ampulex compressa}, and thrips,
\textit{Thysanoptera} spp. The fruit fly, \textit{Drosophila melanogaster}, is
large in comparison to these insects. While the fruit fly flies at $Re \approx
120$, the jewel wasp flies at $Re \approx 60$, and thrips flies at $Re \approx
10$. Differences in the general structures of the wakes generated by each
species are observed. The differences in the wakes correspond to changes in the
ratio of lift forces (vertical component) to drag forces (horizontal component)
generated.
