A group of black ants with relatively large tear-drop shaped abdomens. Probably not the same Sp as at sighting 4664477, (which were within 15 m of this site); the latter had more proportionate heads & thorax relative to their abdomens. But may be the same species as that of sighting 4664574.
@MazzV these aren’t the same as the Sighting 4664477 which I just ID’d for you. These are definitely ants, whereas the other sighting were Ant-mimics (but actually flies)😊
Well I'll be . . . ! I'm still trying to see their wings, but the resolution is too poor. I'm thinking you must be really familiar with these clandestine creatures, you were so quick to pick up on them. Thanks for the linkage to my earlier sighting, it all helps build the knowledge base. Warmest Regards, MazzV
