Detritus (decaying organic matter) and phyllodes of mosses are two main components in the diet of groundhoppers (Orthoptera: Tetrigidae). We studied the energy balance of consumed food under laboratory conditions in the detrito-bryophagous groundhopper, Tetrix subulata (Linnaeus, 1758). The results indicated that the energy food budget of this detr...

In the period 2012–2015, an extensive mapping of the distribution of the Orthoptera in five regions of the Czech Republic (Jihočeský, Karlovarský, Středočeský, Vysočina and Ústecký regions) was carried out. The selected regions cover 43 % of the Czech Republic. The mapping unit used was a standardized square map of the grid mapping, in which the ha...
Article
Detrito-bryophagy represents a specific feeding strategy in orthopterans. We evaluated the consumption rate and digestibility of two main food components (detritus and moss) in a typical detrito-bryophagous groundhopper, Tetrix subulata (L., 1758), under laboratory conditions. By analysing gravimetric consumption, we confirmed that detritus is cons...
Article
Groundhoppers (Tetrigidae) are a basal group of Caelifera that exhibit a conservative feeding strategy associated with the consumption of detritus and lower plants. We studied the feeding strategies and associated morphology of the mandibles of seven tropical groundhoppers from three different subfamilies occupying three different habitats in Borne...

Groundhoppers are considered to be detrito-bryophagous, and moss phyllodes represent a main food consumed by all studied species. We studied the food biology of two groundhoppers: the stenotopic habitat specialist Tetrix ceperoi (Bolivar, 1887) and the eurytopic T. tenuicornis (Sahlberg, 1893). These species occurred syntopically in an abandoned sa...
Article
The antennae of both sexes of the groundhopper Discotettix belzebuth (Serville, 1838) (Orthoptera: Tetrigidae) were examined using scanning electron microscopy. The antennae are composed of 13 segments that differ in their morphology, shape, and spatial distribution of the sensilla. We identified four types of sensilla (coeloconic, placoid, basicon...

Pygmy mole crickets (Tridactylidae) are an interesting but little-known group of Orthoptera; their food biology and dietary preferences have not been adequately studied. Our study focused on the diet composition and associated functional morphology of the mandibles in two European species: Xya pfaendleri Harz, 1970 and X. variegata (Latreille, 1809...
Article
According to a study of type specimens of Discotettix adenanii Mahmood, Idris & Salmah, 2007 and copious specimens of D. belzebuth (Serville, 1838) collected in different parts of Borneo, we found that all species-specific morphological characters of D. adenanii, according to its original description, fall into the morphological variability of D. b...
Article
Many animals change their diet during the season according to food availability. The current field study determined whether the groundhopper Tetrix tenuicornis (Orthoptera: Tetrigidae), which specializes on moss and detritus, changes its diet during the season under conditions in which food components are constantly available. Dietary differences o...

The first recent record of the grasshopper Oedaleus decorus (Germar, 1825) from southern Moravia (Vojenské cvičiště Bzenec Natural Monument, Czech Republic) is given. O. decorus is a very rare species on the northern edge of its distribution. This is the first note discussing its status in the Czech Republic and the circumstances of its discovery a...

Cryptic colouration, adaptation of the tarsi, food preferences and the onthogenetic cycle help the species to survive under extreme conditions. Due to its specific foraging biology it has been used as an excellent model in research on the effects of increased carbon dioxide concentration on the bionomics of herbivo­rous insects in mountain ecosyste...
Article
A study was conducted to determine whether the mandibles of the detrito-/bryophagous groundhopper Tetrix tenuicornis are subject to mechanical wear as a result of feeding, as is the case for grasshoppers that feed on silica-rich grasses. Abrasion was evaluated by measuring the length and width of the 3rd incisor and length of the 4th incisor in adu...
Article
Grasshoppers and katydids (Orthoptera) were studied on the sand dunes of the Hel Peninsula in northern Poland in 2013. Altogether, 11 species of grasshoppers and katydids were identified, three of them can be regarded as elements of the fauna characteristic for sand dunes. Species diversity and population density was higher in seaside with sparse v...

Vodní toky v České republice, stejně jako i v dalších vyspělých zemích byly v posledních 100 letech vystaveny intenzivnímu tlaku lidských zásahů do jejich přirozeného stavu. Tyto činnosti způsobily změnu v biodiverzitě říčních ekosystémů, destrukci vazeb ve společenstvech nebo omezení migrace živočichů např. výstavbou říčných překážek v řekách, kte...

Question
Functional traits are those that define species in terms of their ecological roles - how they interact with the environment and with other species. In terrestrial plant communities, researchers have included more complex traits like rates of growth, nutrient requirements and water uptake. Moss is unique as diet for bryophagous insect, and its problem for evaluate in researches.

Project
Groundhoppers (Orthoptera: Tetrigidae) are detrito-bryophagous insect. Species consume mainly detritus (decomposing organic matter) and lower plants (leaves of mosses). This food strategy is unique between the species of Orthoptera. We focus on the various aspects dietary preferences, food selections or also morphology structures of mouthparts in European species of groundhoppers (Tetrix bipunctata, T. bolivari, T. ceperoi, T. subulata, T. tenuicornis, T. tuerki a T. undulata). Recently, we study food strategies IndoMalaysian species of groundhoppers (Bolotettix, Discotettix, Dolatettix, Epitettix, Thoradonta) and relationships with mandibular morphology and habitat preferences these species.
