Dichromorpha viridis (Scudder, 1862) - Short-winged Green Grasshopper



Nymph
Taxonomy
Family: Acrididae Subfamily: Gomphocerinae Tribe: Orphulellini                                                                                 
Comments: One of four members of this New World genus, three of which occur in North America north of Mexico (Cignlano et al., 2018), and two in North Carolina
Identification
Field Guide Descriptions: Capinera et al. (2004)Online Photographs: BugGuideTechnical Description, Adults/Nymphs: Blatchley (1920); Otte (1981)                                                                                  
Comments: A small, green or brown, short-winged, Slant-faced Grasshopper. Females are usually uniformly colored either green or brown -- with some degree of speckling. Males are more bicolored, often green on the dorsal surface and pale brown on the sides, or pale brown above and darker brown on the sides (Otte, 1981). The lateral carinae of the pronotum are pale and run fairly straight, not constricted in the middle as in other Slant-faced Grasshoppers. The inner sides are not marked with darker bands or triangles -- as in Orphulella or Eritettix -- but the lower sides may be edged with black, but much more narrowly than in Dichromorpha elegans. The remainder of the body and tegmina are either unmarked or may possess small spots.
Total Length [body plus wings; excludes ovipositor]: 15-16 mm, males; 23-27 mm, females (Blatchley, 1920)
Structural Features: The lateral carinae of the pronotum are cut by two sulci, unlike Dichromorpha elegans, where there is just one that cuts across. The wings are usually shorter than the abdomen but long-winged females occur occasionally (Otte, 1981). Antennae are moderately flattened (Blatchley, 1920) and the eye is proportionately smaller relative to head width than in D. elegans (Otte, 1981).
Singing Behavior: Males stridulate during mating to repel other males (Otte, 1970, 1981)
Nymphal Stages and Development: Older nymphs, at least, are colored similarly to the adults and have two sulci cutting the lateral carinae of the pronotum

Habitats and Life History
Habitats: This species occupies a wide range of grassy habitats, ranging from native savannas and shorelines to roadside edges and lawns. Most of our records come from fairly wet habitats and none from the dry-to-xeric grasslands associated with sandhills or rock outcrops.
Diet: Reported to be a grass-feeding species, found on a variety of native grasses as well as turf species (Capinera et al., 1997)
Observation Methods: Best found by walking through its habitat and flushing individuals into making short jumps
Abundance/Frequency: Regularly occurring and often high in density
Adult Phenology: Adults appear in June and persist until at least October
Status in North Carolina
Natural Heritage Program Status:
Natural Heritage Program Ranks: G5 [S5]
State Protection: Has no legal protection, although permits are required to collect it on state parks and other public lands
Comments: This species is widespread and occupies a wide range of habitats, including those disturbed or alterd by human activities. This species appears to be very secure within the state.
