Butterfly was apparently engaged in courting behaviour with another D. plexippus. The one being observed appeared to manoeuvre to keep in front of the other and both climbed in tandem to 200 m, then glided back down to disappear behind the South Building. Two more solitary D. plexippus were also seen. |

straight | level, descend |
288° | left | calm | - | 22.0°C | yes | 50% cumulus |
Butterfly started at 300 m and soared level before gliding down to 200 m. Its descent was gradual. A gull was also seen in field of view. |
| 7 | D. plexippus | 10:57 | 10 m | flap | straight, variable |
climb | 235° | left | calm | - | 23.0°C | yes | 50% cumulus |
Butterfly flapped upward. A second, lower, D. plexippus flew past. |

Two more D. plexippus were seen - one glided down to group of trees, one was flapping SW at 5 m. |
