I guess before they grow up they are small. How we came across this tiny guy is a fair mystery. The human eye is trained to see movement first. It’s a protective defensive kind of thing. So this one moved a little and we had him. If you’re not careful you’d easily miss him. Knowing what you are seeing, now you can see the eye and then you know it’s alive. It was about 4 inches in length. We were darned lucky to see it.
