Adults of E. glaucum scan the growth points and leaves of citrus and False Horsewood trees by flying about 30 mm from them. The damselfly catches adult T. erytreae by picking them from the trees. This is probably the first record of a zygopteran displaying this beha- viour in combination with the predation of a major citrus pest.
