St. Johnswort

Klamath weed beetle

Chrysolina quadrigemina/hyperici: These foliage feeding insects have dramatically reduced the St. Johnswort problem in the Northwest and Pacific states. Damage to the foliage by larval feeding lowers root reserves, making it more difficult for the plant to survive harsh winter and/or dry summer conditions.

$125 per release

St. Johnswort inchworm

Aplocera plagiata: Larvae of this moth feed on leaves and flowers. When numerous larvae are present, the plants are defoliated, and flower and seed formation is inhibited.

$200 per release
