description Snakeweed Grasshopper Overview
The snakeweed grasshopper, scientifically known as Hesperotettix viridis, is an insect native to western North America. It is part of the spur-throated grasshopper subfamily and is recognized as a highly specialized, oligophagous feeder. Instead of consuming a wide variety of vegetation, it primarily eats snakeweed and specific secondary host plants, making its population density highly dependent on the availability of these sources. Agricultural entomologists study this species to monitor its impact on rangeland ecology and weed biological control.
help Snakeweed Grasshopper FAQ
What do Snakeweed Grasshoppers eat?
Unlike generalist grasshopper species that eat a wide variety of vegetation, the Snakeweed Grasshopper is recognized as a highly selective, oligophagous feeder. It primarily consumes snakeweed plants and occasionally a few closely related composite flowers.
Where can the Snakeweed Grasshopper be found in North America?
This specific grasshopper species is native to the western regions of North America. It is frequently found in rangelands, prairies, and semi-arid environments where its host plant, snakeweed, grows abundantly.
Are Snakeweed Grasshoppers considered agricultural pests?
Because they exclusively feed on snakeweed, which is itself considered a toxic, invasive weed on cattle rangelands, these grasshoppers are generally not viewed as crop pests. In fact, their feeding habits are sometimes studied as a potential form of biological control for the weed.
What does the Snakeweed Grasshopper look like?
The Hesperotettix viridis species typically features a bright green body coloration that provides excellent camouflage among the foliage it eats. They often display distinct, contrasting stripes or markings down their backs and thorax.
