This is the Pill Bug or armadillidium vulgareous.The legs are in bronze,the exoskeleton is in stainless steel.And yes ,it is true that this is NOT an insect but a crustacean. It bears an uncanny resemblance to the newly discovered bathynomus giganteuse (18 " long marine crustacean found in 2000 ft. depth)... Not to be confused with a SOW BUG which has two short stickery "tails" and does not roll up into a tight ball. This sculpture is 3 1/2 inches in dia.and made from welded stainless steel and silicon bronze. The little blue spot on the eye is merely the reflection of the blue sky when I shot the piece outside... This piece is available for purchase. Please note me for pricing.
