Some more info on grubs (http://ipm.ncsu.edu/AG271/corn_sorghum/white_grubs.html). Apparently they're not in active feeding right now, that's more in the late summer. They suggest treating the ground for them then, as they burrow over a meter down in the soil for the winter! Also, maturation can take 2-4 years, so I suspect you'd have to treat for several years in a row to make much of a difference. The other thing was definitely a caterpillar of some sort, none of the grub pictures I looked at were similar
