Common Groundhopper

The common groundhopper, <em>Tetrix undulata</em>, is a small insect belonging to the order Orthoptera, family Tetrigidae. This species has an exceptionally broad ecological tolerance and is typically found across virtually all terrestrial and freshwater habitat types within its range. Its distribution spans Belgium, Denmark, Luxembourg, Norway, and Sweden, reflecting a wide presence across northern and western Europe. Unlike most grasshoppers, groundhoppers typically lack fully developed hind wings in some individuals and are often found on bare ground, mossy substrates, and near water margins. <em>Tetrix undulata</em> is assessed as Least Concern on the IUCN Red List, indicating stable populations across its European range. No dietary information has been provided for this species. Biological traits of this species remain poorly documented in the scientific literature.
