Pergid sawflies live in colonies from which foraging groups emerge to feed on plant leaves. These groups can have as many as 30 individuals and move in columns (2-3 abreast) away from the central group towards their feeding areas. We investigated two aspects of this foraging: are certain individual larvae “leaders” of these foraging groups over several feeding bouts and 2) do larvae follow scent paths to the food source. Using marked individuals over 6-8 days of observation, certain individuals do appear in either the first 3 positions or last 3 positions at a higher probability than random chance. Using an artificial “tree” on which branches could be moved, scent trailing was studied. By moving paper/plastic wrap over which larvae had passed, the use of scent following was demonstrated. However, sawflies may have excellent visual systems and landmark use cannot be excluded. The chemical(s) involved in trail following is currently being investigated.
