Agromyza nigrescens

The larva of the Agromyzid fly Agromyza nigrescens mines the leaves of Geranium and Erodium species. The start of the mine is corridor-like and usually follows the leaf margin, before widening considerably into a secondary blotch, with irregular sides. Primary and secondary feeding lines are clearly visible and frass is mostly in large clumps.

Aceria geranii

The mite Aceria geranii causes galls on the leaves of Geranium species.  The leaves are paler than usual, thickened and rolled into a mophead at the shoot tip. The mites live inside the leaves, and are minute, whitish and worm-like; they cannot be seen with the naked eye but are just discernible using a stereo microscope.

Uromyces geranii

Uromyces geranii is a rust fungus that galls the leaves of various Geranium and Erodium species (Crane's-bills and Stork's-bills); there is no host-plant alternation.  Aecia are orange, on leaf undersides and petiole; later pale brown uredinia and darker telia appear on the leaf underside.
