This tiny guy was less than 20mm in length, his head is less than 2mm between the eyes. The bobby pin heads in the shot below are 1mm across.
Magnification is about 2.5x life size, possibly more.
He was scurrying around our courtyard, so I offered my hand and he crawled on. I took him inside and placed him in the bathroom basin. (The basin provides a great light reflector/diffuser.) After about 15 minutes, I took back outside and let him go peacefully. Hopefully he scurry back again soon for another go!
