It has a yellow or white stripe (not spot) on front tibia. Types: Holotype as Ceratina strenua male by Smith, 1879. Type Locality: Texas. In the British Museum of Natural History, London, England. Holotype as Ceratina metallica male by Smith, 1907. Type Locality: Sunbury, Pennsylvania (Baker). Museum unknown. Smith was a professor at University of California, Riverside. The type may be in their insect collection. Note: Harry Scott Smith coined the phrase biological control in a 1919 article in the Journal of Economic Entomology: On some phases of insect control by the biological method.

Life History

Mating from April to May. Females bore new tunnels in twigs of sumac and canes like raspberry and rose. Males die out, females stay in nest until new batch of adults emerge from their eggs in July. The new adults (unmated) use old hollowed-out twigs for over-wintering. One generation per year.

About Flies: the wider group

Order-level background for Hymenoptera, the group containing Ceratina strenua. 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.
