Moved from Leiobunum.

Moved from Harvestmen.

Just an unusual observation / question
It seems to me the legs on these harvestmen have a faint resemblance to antennae on Oecanthinae. (Including a pedicel and scape). I know, it's a stretch of the imagination, but still it makes me wonder if there is any thought of a connection -- from an evolutionary standpoint. I've watched tree crickets use their antennae almost like an outstretched leg - 'to test the waters' so to speak.

Good guess
The second legs are used as sensory appendages in many opilionids. If you're curious and have access to a good research library, I'd recommend "Harvestmen: The biology of Opiliones" by Pinto-da-Rocha et al.
