Among the more common twig ants across the Neotropics is the pleasingly orange Pseudomyrmex simplex. I somehow managed to avoid photographing it until our recent Brazilian adventure, however. Here are a couple shots of workers carrying larvae to safety after I split open a small twig containing a satellite nest.
As these ants are shiny, photographs of them are prone to glare if the light is not sufficiently soft. Here, I spent extra time arranging my mylar diffuser to get the lighting right.
