Mydas Fly

This is not a Wasp.  It is a Mydas Fly and it is an effective wasp mimic.  We believe we have correctly identified your Mydas Fly as Mydas chrysostomus thanks to this BugGuide image.  Of the family, BugGuide notes:  “Life cycle details not known for many groups; generally, larvae live in decaying wood or soil; some known to prey on beetle larvae” and that should explain why they are tunneling in your yard.  Mydas Flies are harmless, so you have no cause for concern.
