The Mound-Building Ant, Formica Exsectoides F., Associated with Tree-Hoppers

Abstract

*[Near Baltimore, this ant feeds upon offall & earthworms, etc. to some slight extent, but its chief food is from other insects; either directly by capture or finding of living or dead beetles, flies, bees, bugs, & larvæ of Lepidoptera, or indirectly by utilization of the honeydew from insects that suck the sap from trees. The protein food from insects seems small in amount as compared with the chief diet of honeydew which is largely carbohydrate.]
