Chicatana Leafcutter Ant

Atta mexicana


Mostly smaller workers, at 8-10mm body length. On these pictures, they can be seen cleaning out their fungus gardens on to a rubbish dump (pictures #5+#6). The cleaning seems to include dead (?) larvae. The rubbish heap covers an area of about 50cm x 30cm.


City park in semi-arid region, at about 1800m a.s.l.

Sorry, only just saw your comment! Apparently most species make underground dumps, so one never sees them. I go out there as often as I can to watch the mound grow.

Interesting Felix. We have tons of leaf-cutter ants here (literally), but I've never seen this before. Thanks for sharing.
