Butterfly gardening

Butterfly gardening

Butterfly gardening is a growing school of gardening, specifically wildlife gardening, that is aimed at creating an environment that attracts butterflies, as well as certain moths, such as those in the Hemaris genus. Butterfly gardening is often aimed at inviting those butterflies and moths to lay eggs as well. Because some plants are not fed upon by adult butterflies, the caterpillar host should also be planted for a bigger population of butterflies. Butterflies typically feed on the nectar of flowers, and there are literally hundreds of such plants that may be planted to attract them, depending on the location, time of year, and other factors. In addition to the planting of flowers that feed butterflies, other means of attracting them include constructing ¨butterfly houses¨, providing sand for puddling, water, and other resources or food items, including rotten fruit.

Why people butterfly garden

There are many reasons why people decide to start butterfly gardening. Some people only like to look at the butterflies, while others like to take pictures as well. Others try to help the butterfly population by planting native plants which rare or threatened butterflies feed on. Done correctly, butterfly gardening can increase the populations of butterflies. Many butterflies are becoming less abundant as a result of habitat destruction and fragmentation, and they do not feed on the plants regularly found on gardens. Others may also help in tagging monarch butterflies, which helps scientists monitor the monarch population and their migratory routes.

Problems

Butterflies have many predators, including mantids, wasps, spiders, birds, ants, true bugs, and flies in the Tachinidae family. If these predators are becoming a problem, they can be controlled with traps. One should never use pesticides to kill predators, as they will also kill butterflies and their larvae. There are also diseases that afflict butterflies, such as bacteria in the Pseudomonas genus, the Nuclear Polyhedrosis Virus, and Ophryocystis elektroscirrha, which only infects queen butterflies and monarch butterflies.

Because insecticides cannot be used, many times aphids and true bugs can infest plants. Aphids can be controlled by releasing ladybugs and other biological pest control agents that do not harm butterflies. Another method of control is by spraying the plants with water, or rinsing plants with a mild dish detergent/water solution (although caterpillars should be relocated before suds are applied). Scented detergents are fine, those containing Oxyclean should be avoided. The aphids will turn black within a day, and eventually fall off.

With small home butterfly gardens, it is common for the lava to exhaust the food source before metamorphosis occurs. Gardeners of Monarch butterflies will often replace the expended milkweed with a slice of pumpkin, which serves well as a substitute source of food.

Butterfly-attracting plants

Research should be conducted as to what species are prevalent in your area, and what plants they prefer to nectar on. Depending on your zone, some butterfly attracting plants include: purple cone flowers (echinacea purpurea), yellow cone flowers, sunflowers, marigolds, poppies, cosmos, salvias, some lilies, asters, coreopsis, daisies, verbenas, milkweed (especially for the Monarch butterfly, whose caterpillars feed solely on this plant), the butterfly bush (budleia), zinnias, and others.

In addition to expanding the number of species seen in your yard, provide host plants that feed the caterpillars. This is just as important as planting flower beds with nectar-rich blooms.
