I found a two-inch grub digging out an old oak stump in early April, incubated in a jar on the counter for a few weeks (where it grew an impressive two inches) and put it back outside a few days ago. Any clues as to what it might be? I thought about keeping it inside until it hatched but I wasn’t sure I could keep the conditions correct and didn’t want to kill it.
This is the grub of a Root Borer in the subfamily Prioninae, but alas we are unable to provide a genus or species. See this BugGuide posting for a similar image.
