Sixty-nine insect herbivores and seven fungi are associated with garlic mustard in Europe. The most important groups of natural enemies associated with garlic mustard were weevils (particularly the genus "Ceutorhynchus"), leaf beetles, butterflies, and moths, including the larvae of some moth species such as the garden carpet moth. The small white flowers have a rather unpleasant aroma which attracts midges and hoverflies, although the flowers usually pollinate themselves. In June the pale green caterpillar of the orange tip butterfly ("Anthocharis cardamines") can be found feeding on the long green seed-pods from which it can hardly be distinguished.
