Effects of zebra mussel attachment on the foraging behaviour of a larval dragonfly, Macromia illinoiensis

1. Larvae of Macromia illinoiensis Walsh are often colonised by the zebra mussel, Dreissena polymorpha Pallas, a recent invader to North America. To determine how mussel attachment affects an individual's foraging behaviour, we quantified capture of Hexagenia limbata Hexes mayfly prey and the distance moved by newly‐molted final instars before and after an individual's colonisation with zebra mussels.
