Dolichoderus attelaboides, Finca Heimatlos, Ecuador

A long slender ant from the Dolichoderus genus, which typically have large colonies. Most species in this genus tap honeydew from other insects.

Note the powdery crystal-like coating on the head and thorax. This is found in many ants and serves to reinforce the exoskeleton. It's a mineral produced by the ant itself, hence the term "Biomineral armor". In case you want to geek out:
