Well if we have to do it ourselves...
- Fungus-growing ants (obvious pick)
- Slaver ants
- Formica rufa (spits acid from its butt)
- Saharan Silver Ant (adapted to the scorching sun)
- Cephalotes (Door head ant)
- Bullet ant
- Giant Amazonian Ants (possibly largest workers)
- (some tiny ant?)
....
- Honeypot ant (10. because they should make the list but I don't want to look at them)
edit: added Formica rufa, Saharan silver ant, Cephalotes
I don't plan on shooting anything weird, but I still don't want anyone looking at my photos! Luckily it's pretty trivial to develop at home, for B&W, at least.
