Host Plants for Butterflies & Moths
Native plants are tied to the lifecycles of numerous butterflies and moths (lepidoptera). Important not only for their nectar, native plants are commonly selected as hosts plants for the caterpillar stage. Some butterflies and moths deposit their eggs on one kind of plant to the exclusion of others, as is the case with Monarch butterflies and milkweeds. Not all are butterflies are exclusive when it comes to which plants will host to their eggs and caterpillars, but they often have preferences.
Caterpillar Friendly Gardening
Last year's leaves, grasses and "yard waste" play an important role in the bio-community of the garden and landscape. Many butterflies and moths over-winter in fallen leaves and spent plant material from the previous season. A light-handed approach to “cleaning up” the garden allows more butterflies and moths to thrive. Avoid raking the ground clean around shrubs and in garden beds, as it can destroy the hibernation environment for the very life that you are trying to support. An article on our blog covers this topic in more detail: Meaningful Maintenance: Fall Clean-up with Positive Impact.
Habitat and Range
The likelihood of seeing particular species of butterflies or moths can be limited by to specific habitat requirements or range. On the other hand, there are many butterflies and moths that range far and wide, and are easily supported, even in urban areas.
