Habitat and Range

Geographic Range

native to the Old World tropics , adventive elsewhere; in our area, established in FL (expanding) and reached TX in mid-1990s (prob. through Galveston on a shipment of plants from FL); infestations reported in many areas as far north as MB, but in cooler areas the ant can only survive indoors (greenhouses, etc.)

About Flies: the wider group

Order-level background for Hymenoptera, the group containing Tapinoma melanocephalum. Species-specific details appear above.

Group overview

Hymenoptera includes over 150,000 described species of ants, bees, wasps, and sawflies. Earth harbors approximately 20 quadrillion (20×10^15) ants, with a combined biomass of ~12 megatons of dry carbon - exceeding the combined biomass of all wild birds and mammals (PNAS, 2022).

Ecological role of the group

About 35% of the world's food crops depend on animal pollinators. The chocolate industry, valued at over $100 billion, depends on pollinating flies and midges. Ants are the dominant soil engineers in most terrestrial ecosystems, turning more soil than earthworms in many habitats.

Economic and practical significance of the group

Pollinators contribute $235-577 billion worth of annual global food production (FAO). In the U.S., bee pollination alone benefits crops valued at $18 billion annually, and honey bees are responsible for $5.4 billion in agricultural productivity. Between April 2023-2024, 55.1% of managed honey bee colonies were lost. The U.S. bee population dropped from 5 million to 2.5 million.
