Additional species information
Species notes from the sources
Etymology: Named for Dr. Richard D. Alexander, Professor Emeritus, University of Michigan-Ann Arbor and a Member of the National Academy of Sciences who discovered the species in Mexico in 1965.

Walker, Professor Emeritus, University of Florida - Gainesville (co-authored by Nancy Collins.)
About Grasshoppers, Crickets, Katydids: the wider group
Order-level background for Orthoptera, the group containing Oecanthus alexanderi. 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.
