Formica ravida. Creighton, 1940

As I indicated earlier, I’ll be attacking a backlog of photographs this season, and here is the first updated gallery, from September 2011: Formica ravida Creighton, 1940 (as identified by James Trager at BugGuide). These ants were photographed in Writing-on-Stone Provincial Park after a rain shower. They were on poplar leaves tending aphids, and the gallery includes images of major and minor workers, defence postures and an attack on a small (unidentified ) chironomid midge that landed too near the aphid colony.

    Nice! The prey in this case looks much like a chiromomid midge.

    Nice pics, I like your aphids! They are Chaitophorus sp.: rather common on Populus and very often tended by ants.

      Thanks Colin! I’ll update the gallery images to show the aphid ID.
