The Mormon cricket, Anabrus simplex, is one of just a few species of katydi
ds (or bushcrickets, Orthoptera: Tettigoniidae) that, like migratory locust
s, appear to have solitary and migratory morphs. Using radio telemetry we s
tudied movements of individuals of two morphs of this flightless species. I
ndividuals within each migratory band had similar rates of movements along
similar directional headings whereas solitary individuals moved little and
showed little evidence of directionality in movement. Our results also add
to other recent radio-telemetry studies showing that flightless insects of
1-2 g in mass can be tracked successfully using these methods.
