This record describes Nomada marshamella (species). Recorded family: Apidae. Recorded order: Hymenoptera.
Identification and Appearance

The female has two yellow tubercles on the thorax which are absent in males. Male lower face yellow. Female antennae all orange, males have partially black antennae. Similar to N. goodeniana and N. fulvicornis . Distinguished by the second yellow band on the thorax being broken by a thin black band. Detailled photros showing key ID features required. Anywhere around the areas where its host Andrena species are nesting. Nomada marshamella has two broods and preys on a variety of Andrena bees including Andrena scotica .

About Flies: the wider group
Order-level background for Hymenoptera, the group containing Nomada marshamella. 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.
