Life Cycle
Eggs are laid in the folds at the margins of dead leaves of leaf fragments. The female seals the edge of the fold to the basal portion of the leaf, forming a pod that encloses the eggs. When hatched, the larvae enter the soil and feed on the roots of the host. Adults feed at leaf margins, cutting out notches.(2)
