181° - 354° 4.0 m/s - - - Butterfly circled to 10 m, glided down to 7 m, found another thermal, and circled and soared upward again.  Another D. plexippus and a soaring J. coenia were also seen.

Two more D. plexippus were seen.  Soaring conditions looked good.
95 D. plexippus - 200 m soar circle - - - - - - yes - Lost sight of butterfly against the sun.  Two more D. plexippus were seen.
96 D. plexippus - 160 m soar circle climb - - - - - yes - Butterfly was one member of a pair that were circling each other as they soared upward (social flight).   The pair continue to circle and soar upward until they vanished nearly directly overhead, making it impossible to get a compass bearing.  Four more D. plexippus were seen.
97 D. plexippus 11:02 100 m soar straight,
(circle)
level 210° (right) 350° 4.9 m/s 21.5°C yes - A group of D. plexippus and an A. vanillae were also seen.
