Thanks for all the suggestions about what my grackles might be eating. Three alternatives have been proposed - Japanese beetle larvae - June bug larvae - cicada larvae I'm inclined to think they are June bug larvae given their relatively large size. Plus my husband reminded me that we had large numbers of June bugs in the area last year where the grackles are now feeding. I don't think they are the 17 year cicadas because the piece of land, where our house and grass is now, would have been heavily wooded 17 years ago. The land had to undergo major rearrangement to make a buildable site when the house was built in 2006 and the cicada larvae would likely not have survived that. Wendy Ealding Powhatan County
