One of several flagging Gleditsia triacanthos with D-shaped exit holes and meandering galleries. Trees aren't yet slated for removal, but I found what looks like a pupa in one of the galleries on the edge of the living tissue. I have been seeing evidence of Agrilus damage on honeylocust trees all over the Minneapolis-Saint Paul metro over the last two years, this is the first time I've stopped to document it on iNaturalist. I've seen A. difficilis damage in Iowa and it looks remarkably similar. I don't think it could be another Agrilus species.
