Dolomedes tenebrosus behavior

[Tortuga]

For reasons unknown to me it appears as if my D. tenebrosus has adopted a piece of bark? She’s been caring this piece of bark around for the past few days and refused to eat this morning. I can only assume she thinks she’s laid an egg sac lol. Any thoughts?
