Nest nests to farm fungi. Ant nests feature an elaborate colony structure that may extend or more underground. As the structure gets further underground, individual chambers become farther and farther apart indicating that the ant is aware of its depth. It is hypothesized that they accomplish this by sensing the level of carbon dioxide in the soil. The leaf cutter ant builds a complex nest which can house 8 million individuals. Its nests feature numerous chambers, most notably garden chambers where they farm fungus on leaves they harvest from the forest. Species such as the carpenter ant and the wasp "Polistes
Green-head ant myrmecophilous insects such as the beetle "Chlamydopsis longipes" are sometimes seen living inside colonies. Green-head ant males are produced irregularly throughout the year and are low-flying ants. Recorded nuptial flights begin between September to November at temperatures of 20–25 °C (68–77 °F), when a number of males begin to emerge from their nest. Sometimes, however, the males may return to their nest after briefly appearing outside. The green-head ant is a gamergate species, which means that males can successfully mate with the workers. These workers remain outside their nest with their head and thorax appressed and gaster elevated into the
