1 | Battus philenor | 9:41 | 2 m | flap | straight | level | 250° | - | - | - | - | - | - | Wingbeats of B. philenor (pipevine swallowtail) were more fluttery than usual. |
2 | Danaus plexippus | 9:47 | 0.5 m | flap | variable | level | 168° | - | 345° | 1.6 m/s | - | yes | - | Butterfly appeared old (i.e. faded and worn) - probably was not a migrant. Swifts were foraging and vultures were soaring to 45 m. A Phoebis sennae (cloudless sulphur) was foraging. |
- | - | 10:07 | - | - | - | - | - | - | 347° | 2.3 m/s | - | yes | - | - |
3 | D. plexippus | 10:09 | 150 m | soar | straight | level | 190° | - | 347° | 2.3 m/s | 25.5°C | yes | thermal puffs |
Wind had become gusty - thermals were developing. |
4 | D. plexippus | 10:36 | 20 m | flap | straight | climb | 210° | - | 347° | 2.3 m/s | - | - | - | The D. plexippus also appeared old. It was chased by a Junonia coenia (common buckeye). WW: Radar detected a few low targets that did not show a consistent pattern of orientation. |
5 | D. plexippus | 10:56 | 30 m | soar | circle, straight |
climb, level |
190° | - | 335° | 2.7 m/s | 25.5°C | yes | - | Butterfly started at 20 m. Vultures were soaring, swallows and swifts were foraging in flocks. |
6 | Tramea lacerata | - | 10 m | flap, soar |
erratic | level | S | - | N | - | - | yes | strato- cumulus |
A dragonfly with two common names - jagged-edged saddleba and black. saddlebag. A P. sennae also flew past. |
7 | B. philenor | - | - | flap | straight | climb | 222° | - | 347° | 3.5 m/s | - | yes | - | This B. philenor had more fluttery flight than usual. Swifts were foraging. |
8 | Phoebis sennae | 11:30 | - | flap | straight | level | 180° | left | 348° | 2.2 m/s | - | - | - | - |
- | - | 11:35 | - | - | - | - | - | - | - | - | - | - | - | WW: Radar showed that no butterfly-like targets were flying above 300 m. |
9 | B. philenor | 11:44 | 1 m | flap | straight | level | 275° | right | 346° | 3.0 m/s | 25.5°C | - | - | - |
