Hello, we live in SE Wisconsin, USA. Last night we found a grub or
caterpillar which had rows of phosphorescent green dots down its back. The
insect was in the grass, about four feet away from a Maple tree.

Viewed under a flashlight, the insect appeared to be a "plain," tan-colored
grub about 1.5" long.

This was not a "glow worm" - it was much larger and fatter.

Can anyone identify this grub and tell us the function of the glowing dots?
