flight strategies in species of fruit flies
Observing different species of fruit flies offers an opportunity to
strategies for insects of varying size but of nearly identical body and
architecture. Using automated three-dimensional high-speed videography,
captured many beautiful flight sequences of untethered fruit flies.
From this data
we have extracted the complete body and wing kinematics and determined
forces acting on the wings using custom-written tracking and analysis
find that, in addition to lift, drag plays an important role in
vertical force needed for these insects to stay aloft. Moreover, our
data base in
combination with various numerical analysis techniques is allowing us
whether these insects are flapping in the most efficient manner
possible. Answers to
this line of questions are important for determining what role if any
played in determining how these insect fly.
