Identification and Appearance

Entypus fulvicornis - Entypus fulvicornis
Contributed by Nick Fensler; Additional contributions by PaleoJon

A black-bodied species with black wings and orange antennae. Distinguished from E. magnus by the following combination: interrupted or strongly subapically narrowed brush on the inner side of the hind tibia (narrowed more weakly in E. magnus ); strongly developed nipples on the apical margin of the fore coxae (weakly developed in E. magnus ); and female with distinct pair of tubercles on S2 (only weak swellings, not proper tubercles, in E. magnus ).

About Flies: the wider group

Order-level background for Hymenoptera, the group containing Entypus fulvicornis. 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.

Recorded sources for this group: FAO, USDA, EPA, PNAS (2022), US Fish & Wildlife Service. Imported estimates may describe particular regions or reporting periods.
