HopperWiki is an evolving project. Please help us by exploring the site and reaching out to us if you have corrections, comments, or information you'd like to provide for the public good! Note that much of the core structure of the wiki is still being actively developed.

What is HopperWiki?

HopperWiki is designed to serve as a global repository of information for all Orthoptera. The project, led by the Global Locust Initiative at Arizona State University, brings together experts from diverse fields to create original content and facilitate access to the wealth of existing resources on the world’s ~30,000 described species of orthopteran insects. In addition to species profiles which are built on the foundational taxonomic database of the Orthoptera Species File, HopperWiki aims to enhance the accessibility of researchers and organizations working on Orthoptera. A key focus is compiling resources that address the complex challenges of sustainably managing locusts and pest grasshoppers, which have significant impacts on human livelihoods and the environment.

NEW APHIS rangeland portal

The Rangeland Community Management Portal is a collaborative effort between ASU's Global Locust Initiative and APHIS's Insect Management and Molecular Diagnostics Laboratory in Arizona. This collaboration is developing an interactive resource that connects users to biological and management information for the top pest grasshopper species in the western United States. An interactive map allows quick access to the 17 western states that are managed for rangeland grasshopper threats. Summary information is provided on the ecology and grasshopper management history of this region. By combining ecological insights, historical data, and practical tools like identification guides, the portal helps communities, ranchers, and land managers in their efforts to safeguard rangeland productivity and resilience.

Featured person

Alexandre Latchininsky is an internationally recognized expert in locust ecology and management, with decades of experience in research, field operations, and capacity building across affected regions. One particular focus is locust management in the Caucasus and Central Asia. He is the author of many publications and resources including the recent Practical guidelines on locust and grasshopper monitoring in Caucasus and Central Asia.

Featured resource

This document features practical guidelines in English to improve locust and grasshopper monitoring in Caucasus and Central Asia. The publication promotes year-round surveillance, early detection, standardized data collection, and regional cooperation to help countries act before outbreaks spread and damage crops and pasturelands. It also highlights the use of tools like GPS, digital reporting systems, drones, and remote sensing, while emphasizing economic thresholds to guide timely, targeted control and reduce unnecessary pesticide use.

Orthoptera Species File

Behind every scientific name on HopperWiki lies the careful work of the Orthoptera Species File (OSF). For decades, OSF researchers have tracked, organized, and preserved the nomenclatural history of Orthoptera, creating a stable framework used by scientists and biodiversity projects worldwide. HopperWiki builds upon this foundation to bring together species information, images, literature, and observations in a unified resource. Read more…

Featured species

The migratory grasshopper (Melanoplus sanguinipes), is a spur-throated grasshopper widespread across North America, particularly in central and western regions. It is thought to be a close relative of the extinct Rocky Mountain locust (Melanoplus spretus) that swarmed the Great Plains in the 1800's. M. sanguinipes is a medium to large grasshoppers and is considered one of the most abundant and destructive pests to rangeland and agriculture in the North American West. It is a generalist feeder and thrives in degraded or weedy landscapes. They are known for their ability to migrate in swarms, especially during outbreaks. The economic impact of their outbreaks along with other species leads to the treatment of millions of acres of range and cropland each year. Click here for more details.
