Grubs are the larvae stage of the June bug. In our area most are the
European Schaefer (sp?). They live as a grub for 3 years, then pupate into
June Bugs in late June/ early July. They fly, mate and then the females drop
eggs onto the lawn which hatch in the late summer and so the cycle
continues.

June bug? what about crane fly ? thought grubs were from crane fly ...
