Seems to appear when you least expect it. Just on the flowers (you should be familiar with the flowers in the picture) for a short moment, before she took off to the treetops again. This is next to the area where we usually rest when we are waiting for the puddlers at Simon's Spa.
But no chance to get a better shot. The one that I earlier shot was a male, and Horace subsequently nailed another male. This one's a female. The host plant must also be nearby cos this is the 2nd time I saw it there.
