Moses Olotu examines ants under the microscope at Ant Course 2012 in Uganda.
Winkler extraction bags hang in Kibale forest, Uganda. Each contains several mesh sacks filled with leaf litter sifted from the forest. Arthropods walking about in the litter fall out and collect in plastic bags full of ethanol. This method has proven highly productive for sampling the cryptic rainforest micro-fauna, resulting in hundreds of new species.

Myrmecologists often start new laboratory colonies from young mated queens. This Solenopsis molesta thief ant queen was collected after her midsummer mating flight and placed in a standard test tube nest. University of Illinois at Urbana-Champaign, Illinois, USA

Formica obscuripes nestmate workers engaging in trophallaxis, or the social sharing of liquid food. Wisconsin, USA
Formica obscuripes nestmate workers engaging in trophallaxis, or the social sharing of liquid food. This behavior does more than merely transfer food. Ants also use it to pass chemical signals among each other, and research has shown that trophallaxis helps the colony maintain a cohesive identifying odor. Wisconsin, USA
