This record describes Ammophila pictipennis (species). Recorded family: Sphecidae. Recorded order: Hymenoptera.

Identification and Appearance

Ammophila pictipennis - Ammophila pictipennis
Contributed by Cotinis; Additional contributions by KenW , PaleoJon , Arturo Santos

A very conspicuous eastern species with brightly-pigmented orange wings and no silvery markings on the thorax whatsoever. In the west, see also A. placida , which is separated by the structure of the male genitalia. Those of A. pictipennis lack a spine on the penis valve head. The two species overlap from about 96° to 104°W, where they are otherwise impossible to separate.

About Flies: the wider group

Order-level background for Hymenoptera, the group containing Ammophila pictipennis. 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.
