They can be so complex, so inscrutable....
Keep an eye on her - watch for any signs of lethargy, droopiness, staring off into space, loss of appetite, etc.
But my gut feeling - based on the time of year - she may be on the lookout for a place to lay her eggs secretly. So watch that one. Don't want her to disappear.
Another possibility is she may have a strong foraging instinct that has her exploring a larger territory, or there could be a low-level conflict you don't see.
Hmmm... I hope it's a laying thing, because at least then I already know what spot she's got her eye on, since I usually end up finding her under the same little cluster of bushy trees. She's always been a bold one...
