Strange Stance

Hello all, My Female Emp gave birth 2 months (ish) ago, still sharing with the Slings, all going well. However today i found her half in half out of her burrow, with her pincers out sreached, and her mouth parts fully outstreched. I thought she was dead. Until i took the lid off n she scurryed back down her burrow. Any idea what this was. Ive never seen it before????

A good morning yawn.... Maybe it was a feed me I'm hungry pose....

Seriously though it could just be one of those weird stances (Stilting) they do when it is too hot or something.
