A variety of species in the Lily family serve as hosts for the leek moth. Leek is the preferred host. Other hosts include onion, chives, garlic, and shallot. We do not know if the leek moth will feed on weeds outside of the agro ecosystem. Several wild native Allium spp. could be attacked.
Fruits and Vegetables
The leek moth is considered a serious pest. Environmental damage to native species is also possible. The leek moth is frequently intercepted and there is nothing to stop the natural spread across the border from Canada. Given all these pathways, the entry potential for leek moth is high.
The leek moth is not known to occur in Indiana.
