Poison Hemlock

Hemlock defoliating moth

Agonopterix alstroemeriana: The larvae of this moth defoliate the plant by consuming leaves, stem tissue, flowers, and seeds. The damage/defoliation is often severe. Moths over-winter as adults and are very hardy. Our collection season may not coincide with more temperate climates, so we have developed methods to ensure establishment at your location.
