Chortophaga viridifasciataGreen-striped Grasshopper

Ge­o­graphic Range

Chor­tophaga virid­i­fas­ci­ata, com­monly known as green-striped grasshop­pers, are found through­out North Amer­ica. Their range stretches from New Brunswick and Geor­gia west to Ari­zona, Saskatchewan, and British Co­lum­bia. They may be found in Mex­ico and as far south as Costa Rica. They may be found in iso­lated colonies west of the Rock­ies in areas used for agri­cul­ture. (Brust, et al., 2008)

Habi­tat

Green-striped grasshop­pers pre­fer liv­ing in moist habi­tats. They can be found near road­sides, hay mead­ows, pas­tures, and sunny areas of grass. They can be found in many moist, sunny, grassy areas in the east­ern parts of their range. Their habi­tats are less com­mon in the west­ern parts of their range due to their pref­er­ence for moist habi­tats. (Brust, et al., 2008; Coin, 2005)

Phys­i­cal De­scrip­tion

Green-striped grasshop­pers are be­tween 23-38 mm in length. Males are 23-30 mm, while the larger fe­males are 28-38 mm in length. Some may be tan in color. Males are often brown in color and fe­males are often green. Males have larger heads and thicker legs. Fe­males have thicker, longer ab­domens com­pared to males. They have yel­low­ish wings that are smokey near the tips. They have a green or brown stripe close to the bor­der of their front wings. Their pronota are ridged. Green-striped grasshop­pers have com­pound eyes and an­ten­nae that are brown­ish in color. Nymphs in their first three in­stars are green in color. (Coin, 2005)

South­ern pop­u­la­tions have bolder pat­terns. They may have dark bars stretch­ing across their front wings and hind femora. The smokey color near the tips of their wings is darker than those from north­ern pop­u­la­tions. (Coin, 2005)

  • Sexual Dimorphism
  • female larger
  • sexes colored or patterned differently
  • sexes shaped differently

De­vel­op­ment

Green-striped grasshop­pers have a well-syn­chro­nized de­vel­op­ment, with most in­di­vid­u­als pass­ing through life stages in par­al­lel. Fe­males lay eggs in the spring. Most eggs hatch within a two week pe­riod in the mid­dle of July. Nymphs grow slowly in the north­ern part of their range. They pass through five in­stars of de­vel­op­ment. They may take up to 100 days to reach their fourth in­stars. A large num­ber of nymphs enter their fifth in­star be­fore over­win­ter­ing while in hi­ber­na­tion. Un­like dif­fer­en­tial grasshop­pers, green-striped grasshop­pers do not un­dergo di­a­pause. Nymphs be­come ac­tive again in March. Green-striped grasshop­pers un­dergo in­com­plete meta­mor­pho­sis in early April to be­come adults. (Brust, et al., 2008; Hall Bo­d­ine, 1932; Pfadt, 1994)

Re­pro­duc­tion

Males make a crepi­tous sound to at­tract po­ten­tial mates. In­ter­ested fe­males ap­proach males by fly­ing and re­turn­ing the crack­ling call. The pair walks and hops to­wards each other as a courtship rit­ual. After mat­ing, the fe­male will dig a hole and lay the eggs pods in­side of it. Each egg pod con­tains 25 eggs. (Brust, et al., 2008; Pfadt, 1994)

  • Breeding interval
    Green-striped grasshoppers breed yearly.
  • Parental Investment
  • no parental involvement

Lifes­pan/Longevity

Adults can be found dur­ing the spring and sum­mer in the north­ern part of their range. They can be found all through the year in the south­ern part of their range. Green-striped grasshop­pers are sin­gle-brooded. In the south­east, they may have mul­ti­ple broods per year. In the far south, adults may be found year-round. (Coin, 2005)

Green-striped grasshop­pers over­win­ter in their nearly-ma­ture nymphal stage, un­like many other species of grasshop­pers. (Coin, 2005; Hall Bo­d­ine, 1932)

Be­hav­ior

Green-striped grasshop­pers are mo­bile in their nymphal and adult stages. They live in large groups. Adults are very strong fliers. (Coin, 2005)

Com­mu­ni­ca­tion and Per­cep­tion

Dif­fer­en­tial grasshop­pers have com­pound eyes. They likely use tac­tile, vi­sual, and chem­i­cal chan­nels of per­cep­tion. Tac­tile, vi­sual, and chem­i­cal meth­ods of com­mu­ni­ca­tion are pos­si­ble. (Pfadt, 1994)

Food Habits

Green-striped grasshop­pers mostly eat grasses and suc­cu­lent plants. They feed on plants species like Ken­tucky blue­grass, fox­tail bar­ley, quack­grass, lit­tle bluestem, june­grass, needle­leaf sedge, Penn sedge, Eu­ro­pean stick­tight, or­chard­grass, poverty oat­grass, an­nual sowthis­tle, John­songrass, graz­ing brome, and mem­bers of the genus west­ern wheat­grass. (Coin, 2005; Pfadt, 1994)

Green-striped grasshop­pers feed on the edge of leaves about halfway up. They may eat through the leaf, hold on to the cut part, and feed it into their mouth­parts. (Coin, 2005; Pfadt, 1994)

Pre­da­tion

Bris­tle flies, flesh-eat­ing flies, and par­a­sitic wasps are par­a­sitoids that prey on nymphs and adults. (Coin, 2005; Pfadt, 1994)

Ecosys­tem Roles

Green-striped grasshop­pers eat many types of plants, in­clud­ing grasses, crop plants, and suc­cu­lents. Bris­tle flies, flesh-eat­ing flies, and par­a­sitic wasps are par­a­sitoids that prey on nymphs and adults. (Amand and Cloyd, 1954; Coin, 2005)

Eco­nomic Im­por­tance for Hu­mans: Neg­a­tive

In the east­ern part of the United States, green-striped grasshop­pers may dam­age pas­tures, hay­fields, and crops like red clover. They typ­i­cally dam­age crops min­i­mally. (Pfadt, 1994)

metamorphosis

A large change in the shape or structure of an animal that happens as the animal grows. In insects, "incomplete metamorphosis" is when young animals are similar to adults and change gradually into the adult form, and "complete metamorphosis" is when there is a profound change between larval and adult forms. Butterflies have complete metamorphosis, grasshoppers have incomplete metamorphosis.

motile

native range

the area in which the animal is naturally found, the region in which it is endemic.

oviparous

reproduction in which eggs are released by the female; development of offspring occurs outside the mother's body.

seasonal breeding

breeding is confined to a particular season

sexual

reproduction that includes combining the genetic contribution of two individuals, a male and a female

social

tropical savanna and grassland

A terrestrial biome. Savannas are grasslands with scattered individual trees that do not form a closed canopy. Extensive savannas are found in parts of subtropical and tropical Africa and South America, and in Australia.

savanna

A grassland with scattered trees or scattered clumps of trees, a type of community intermediate between grassland and forest. See also Tropical savanna and grassland biome.

temperate grassland

A terrestrial biome found in temperate latitudes (>23.5° N or S latitude). Vegetation is made up mostly of grasses, the height and species diversity of which depend largely on the amount of moisture available. Fire and grazing are important in the long-term maintenance of grasslands.
