Lily grub

- Infects - Flowers, Foliage,
- Host plants- Lily, Alstromeria,
- Symptoms- Holes in leaves: Leaves eaten: Black slime on leaves: Red beetles on plants:
Within a few days of the adult beetles arriving at your lily plants, clusters of eggs are laid on the undersides of the foliage. If left to hatch, orange grubs emerge and set about defoliating your prize lilies.
As they grow, these grubs cover themselves in a ball of their own excrement such that the plants look like they are covered with small balls of dung that slowly move over the leaves, stripping them as they go. Once the warmer weather of summer sets in, the lilies will receive daily visits from more beetles, and plants will have eggs, grubs and adult beetles present at the same time. Successive generations will reduce lily plants to bare stems in a matter of weeks, then they eat the stems.
Wiping these grubs off your lilies by hand is not a pleasant occupation but is pracical if you only have a small number of plants. Spraying with a systemic insecticide will produce far better results as this will also kill off the adults as they nibble at the leaf edges.
