Several of these insects are burrowing holes in the sand in our backyard. We seen three of these bugs carrying Angular-Winged Katydid back to their burrows. I killed two of the bugs and took some photos of them. What are they?
Great Golden Digger Wasps, like the two dead individuals in your photograph, are a beneficial species that pollinates plants as adults, and the larvae feed on Katydids which are provided by a solitary female who digs a burrow that she provisions with paralyzed Katydids to feed her brood. Great Golden Digger Wasps are not an aggressive species. While we concede that the possibility exists that they might sting someone, we have never received a report that anyone has been stung by a Great Golden Digger Wasp. In our opinion, these magnificent wasps have been killed needlessly, so we are tagging this posting as Unnecessary Carnage. Your letter only indicated that the Great Golden Digger Wasps were digging and capturing prey. You never indicated if they threatened you or your family.
