HymenopteraIchneumonidae – Ichneumonid Wasps

Grotea lokii

This record describes Grotea lokii (species). Recorded family: Ichneumonidae. Recorded order: Hymenoptera.

Identification and Appearance

Grotea lokii - Grotea lokii
Contributed by Jonathan Hoskins; Additional contributions by egordon88

Almost identical to its eastern analogue, G. anguinea in coloration. Distinguished by a brownish spot in the forewing (either conspicuous or faint) and by the lack of a deep-orange dorsal band on the pronotum. Legs may be slightly more yellow-orange rather than orange. The clypeus is also more faintly pentagonal than in G. anguinea .

About Flies: the wider group

Order-level background for Hymenoptera, the group containing Grotea lokii. 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.
