Formica Ants | DelmanExpert Pest Control Service
Formica is a genus of ants of the family Formicidae, commonly known as wood ants, mound ants, thatching ants, and field ants. Ants of this genus tend to be between 4 and 8 mm long. As the name wood ant implies, many Formica species live in wooded areas where no shortage of material exists with which they can hatch their mounds. However, sunlight is important to most Formica species, and colonies rarely survive for any considerable period in deeply shaded, dense woodland. This is a sweet substance that they get from insects like mealybugs and aphids. They find the aphids on trees and shrubs. Some species of field ants, like the silkyants, Formica fusca, keep herds of aphids so there is always a supply of honeydew. Field ants also eat other insects.
