Stem mining weevil

The larvae of this hardy weevil hatch on young leaf or stem tissue. They bore into the plant and mine towards the main stem. Older larvae mine the stem, crown, and root. The plant’s root reserves are reduced by an average of 50% in attacked plants. Canadian research showed that the incidence of a fatal rust fungus disease was more than doubled when the insect is present.
