“…It is one of the largest and best researched of the hemimetabolous insect orders and consists of two suborders, the Caelifera (Acidoidea or Acrydoidea) and Ensifera (Tettigoniedea) (Handlirsh 1930;Ander 1939), which are widely accepted by most researchers. With regard to mid-level Caeliferan or Ensiferan relationships (among superfamilies, families, or subfamilies, respectively), there are a few hypotheses based on morphological and molecular data (Flook and Rowell 1997a, 1997bFlook et al 1999Flook et al , 2000Fenn et al 2008;Ma et al 2009;Eades and Otte 2010;Sun et al 2010;Zhao et al 2010Zhao et al , 2011. The lack of a consensus as to the phylogeny based only on morphologies makes it especially critical to use DNA data from highly polymorphic genetic markers such as mitogenomic sequences.…”

Background: The phylogeny of the Orthoptera was analyzed based on 6 datasets from 47 orthopteran mitochondrial genomes (mitogenomes). The phylogenetic signals in the mitogenomes were rigorously examined under analytical regimens of maximum likelihood (ML) and Bayesian inference (BI), along with how gene types and different partitioning schemes influenced the phylogenetic reconstruction within the Orthoptera. The monophyly of the Orthoptera and its two suborders (Caelifera and Ensifera) was consistently recovered in the analyses based on most of the datasets we selected, regardless of the optimality criteria.

“…In the pygmy grasshoppers (Tetrigidae), which are small, ground dwelling orthopterans that form an ancient clade within the short-horned suborder Caelifera (Flook & Rowell, 1997), there is a similar pattern. In this group, the forewings are reduced to a 1-3 mm long tegmentulum (Devriese, 1996), while the pronotum is prolonged and covers the abdomen and hind wings.…”

Abstract. Dimorphism in wing length is well known in many insect species. It is generally believed that a trade-off between dispersal and reproduction exists, with the long-winged (LW) morph being a better disperser due to its superior flight capability. The short-winged (SW) morph is less mobile and it is hypothesised that females of this morph invest more of their energy reserves in producing offspring. We determined the variation in body and wing size in the pygmy grasshopper Tetrix subulata (Orthoptera: Tetrigidae). The results of the morphological study support the occurrence of two clearly distinct wing morphs in both sexes. SW individuals, especially males, were smaller and in accord with proposed developmental instability showed greater variability in body size than LW individuals. Using data for 700 wild-caught individuals from 10 populations, we demonstrate a variable frequency in the percentage of LW individuals, ranging from all-LW to all-SW populations, even if the LW morph is by far the most common morph in an area. The male-biased percentage of LW individuals recorded in intermediate populations supports a difference in the dispersal reproduction trade-off between the sexes.

“…They are considered to represent the most basal lineage of the true grasshoppers (Flook et al, 1999;Flook and Rowell, 1997), and despite their common name are not closely related to true crickets or mole crickets. These insects are only a few millimetres long but are widely distributed across the warmer parts of the globe.…”
