SEM of anal end of black garden ant
Scanning electron micrograph (SEM), tinted orange, of the gaster, or anal end, of a black garden ant (Lasius niger), where a jet of formic acid is expelled as a defense against potential attackers. The fringe of hairs surrounding the hole is characteristic of the black ant. This species lives under flat stones at the edges of lawns & paths, feeding on caterpillars, earwigs, woodlice & other ants. It has a close relationship with Aphis fabae, the broad bean aphid, which it milks for a drop of honeydew for additional nourishment. In return the ant protects the aphid by removing nearby eggs of predators such as ladybirds & lace- wings. Magnification: X 145 at 35mm size. Original is BW print Z345/054
