Don Holbrook had posted a shot of an unknown moth, <
http://zone-10.com/tope2/main.php?g2_itemId=22864>, and, on a hunch, I
suggested to Don off-list to put "Pterophoridae", or plume moth, into
Google Images. Don agreed with my hunch on an ID. Going a step farther,
try "Alucitidae", or many-plumed moth, in Google Images. I could hardly
believe what I was seeing the first time I tried to spread one out on a
pinning board. Maybe Jim N. could tell us a bit about the aerodynamics of
a wing structure like these guys have. Getting down to the ultra-small
insects flying around, put "Mymaridae" into Google Images. Some of these
guys are so tiny that flying, to them, is like a human trying to swim in a
pool of ping-pong balls. Or something like that. A few species of
mymarids have wings that look not like a wing but like a canoe paddle with
fine hairs along the margins. Again, molecules of O2 or N2 in air look
quite a bit different to something 2 mm long than do these molecules look
to a 747 at 600 mph. (I never got to even the basic understanding of
Reynold's Numbers. Sorry, Jim.)
