Coexistence takes place in the rainforest of Panamá. The video consists of a parade of leaf-cutter ants, carrying off a collection of leaf fragments. Interspersed with the organic matter is some artificial material—the intervention of the artist. Bits of paper, situated as leaf-fragments, are painted with the national flag decorations of the 191 members of the United Nations. The complete action originally lasted about one hour; however, the final video was edited to include the flags of nations, which have been involved in military conflicts in recent history. Juxtaposed with peace symbols, which are also staged as leaf fragments, Coexistence reflects upon the duality of human nature—war and peace—while commenting upon the relationship of human and nature.

In 2003 Conlon received Second Prize in the First Central American Emerging Artists Exhibition at the Museum of Contemporary Art and Design in Costa Rica for this video work.

The artist describes her work as "a socio-archaeological inquiry“ in her immediate surroundings. She collects and accumulates ordinary images, objects and repeated actions from her daily life and local environment. Then she uses them to "reveal the idiosyncrasies of human nature and the contradictions inherent to our contemporary lifestyle."
