These are super fast too!
Moving sideways quickly and "disappear" when they found
a suitable spot to camouflage, then you have to look for it again.
I will try to video a Hersiliid the next time I spot one to show you
how they move around and hide.

Wow! Ours are just tiny by comparison then. I'd like to see these in action. Ours are incredibly fast movers.

ChunXingWong 7 years ago

It is a fairly large one.
I guess about 10 - 20mm in length from forehead to abdomen,
spinnerets length excluded.
