Black-winged Grasshopper

Trimerotropis melanoptera

This record describes Trimerotropis melanoptera (species). Recorded family: Acrididae. Recorded order: Orthoptera.

Identification and Appearance

Black-winged Grasshopper - Trimerotropis melanoptera
Contributed by Brad Barnd; Additional contributions by David Ferguson

Only likely to be confused with Trimerotropis latifasciata (see comments under that species ). The reddish abdomen and underside, and the broad black band that nearly dominates the otherwise pale wings are distinctive features. Resembles Spharagemon equale rather closely with wings folded, but it is a bit more slender, the top of the pronotum is less roof-like and more flat, the median ridge on the pronotum is lower, and the hind wing coloration is quite different. Like T. latifasciata and several Spharagemon species, this one has an attractive collared form in which the rear half of the pronotum, face and sides of head, and bands across legs can be pale pinkish, tan, or nearly white. One of the most striking species of grasshoppers in North America, often very abundant, and yet for some reason not often noticed, perhaps because people tend not to frequent its prefered dusty habitats. It sometimes turns up on athletic fields and vacant lots in towns, perhaps because they resemble it's habitat, and because it is often attracted to bright lights. It has a tendency to stand tall and display it's reddish abdomen, a behavior that is apparently not studied yet. It is an alert, highly active species, rather difficult to catch and to photograph. It is noisy in flight, producing a loud harsh interrupted buzzing (pulse buzz). Apparently closely related to T. latifasciata , and also apparently to Spharagemon .

Habitat and Range

Habitat

Usually in valley bottoms and flats on bare silty, eroded, tilled, or slightly saline soils, usually with sparse grass cover. Often found gathered in large numbers on relatively level disturbed bare patches such as around cattle watering ponds or tanks, ant hills, Prairie Dog towns, tops of gentle dirt banks along roads or arroyos, etc.

Geographic Range

Short-grass steppe regions. Roughly south of the North Platte River in se. Wyoming and sw. Nebraska, southward across e. Colorado e. New Mexico, westernmost Kansas, Oklahoma Panhandle, and Western Texas, and across much of the upland interior of Mexico. West across southern New Mexico and northwest Chihuahua to south-central Arizona and north-central Sonora.

Seasonal Activity

Overwinters as eggs. Adults summer to frost, but usually most common in July or August.

Additional species information

Species notes from the sources

Etymology: The name " melanoptera " refers to the largely black wings.

About Grasshoppers, Crickets, Katydids: the wider group

Order-level background for Orthoptera, the group containing Trimerotropis melanoptera. Species-specific details appear above.

Group overview

Orthoptera includes ~28,000 described species of grasshoppers, crickets, and katydids. Desert locusts can form swarms covering 460 square miles containing up to 80 million individuals per square kilometer.

Ecological role of the group

Grasshoppers and crickets are a primary food source for birds, reptiles, and small mammals. Cricket farming is a growing industry - crickets require 12× less feed than cattle to produce the same amount of protein, using 2,000× less water.

Economic and practical significance of the group

A single large locust swarm can consume the same amount of food in one day as 35,000 people. The 2019-2021 East Africa locust crisis affected food security for 42 million people across multiple countries. Global crop losses from locusts can reach billions annually.

Recorded sources for this group: FAO, UN World Food Programme, research publications. Imported estimates may describe particular regions or reporting periods.
