Don't monkey with the durians.
I frequently see trap-jaw ants (the genus is Odontomachus) in Costa Rica, where they tend to be golden brown. This Malaysian beauty is much darker and sports some beautiful ornamentation on her head. Her jaws are in the relaxed "off" position. If she spreads them wide in the cocked position, tiny hairs on the jaw will cause them to slam shut if she bumps into a small insect.
I got my party pants on. Also, check out the spines on the leaf.
