tracked movements of a radio-tagged monarch butterfly

Iowa State University researchers are learning about the fine-scale movements of monarch butterflies (Danaus plexippus) in unprecedented detail via the use of radio telemetry. Research team members using antennas track butterflies tagged with radio transmitters at one-minute intervals. This map shows the path followed by one tracked butterfly. Small circles indicate estimated locations, labeled by minute of observation. Lines connecting points represent the straight-line steps between the points. Large ovals represent the zone of error calculated for each estimated location. (Image originally published Fisher et al 2020, Environmental Entomology)
