Have you ever noticed that certain varieties of spiders can convey emotion through their eyes? Particularly Orb Weavers.
They show worry, concern, anger, love, happiness, sadness, the lot.
I've noticed this on (can only identify as a Cavatica) my grey spider (with red between the joints) she actually has an articulating brow.... casual informal wedding wears dressed in summer
Her mate is not present on her web as of today, and tell tale signs of a bird attack.
She's not repairing her web, nor is she eating.
Makes me sad.
