Habitat loss, climate change and pesticide use have decreased butterfly populations.
Unbeknownst to many butterflies do not live on nectar alone, some species prefer, even require, overripe fruit to feed on. Decaying fruits have carbohydrates and minerals, neccessary to most butterflies. Supply them with flowers, fruit, water and plants for their caterpillar stage, and you will hopefully have a large and happy, diverse population.
Best Food for Butterflies
Watermelon turns rather rapidly, feeding overripe fruit to butterflies, seems like a perfect purpose for it. There are approximately 20,000 species of butterflies in the world. About 725 species can be found in North America/north of Mexico, approximately 2000 species in Mexico, 3500 in Peru, 275 species in Canada and 440 in Europe. Photo by Toshio, Flickr.
Fruit dehydrates and seals up, therefore slices need to be cut into the fruit daily, making more juice available. A blue Morpho drinking banana at lewisginter.

Butterflies love red, orange, purple and yellow. Butterflies have good color vision sensing more “wavelengths” than either humans or bees.
Butterflies are particularly fond of oranges, grapefruits, cantelope, strawberries, peaches, nectarines, kiwi, apples, watermelon and bananas, especially mushy bananas that have been stored in the freezer and then thawed. Some species love a “brew” of rotting fruit, molasses, beer, and brown sugar. Some like moist mushroom compost.
Hummingbirds and some species of butterfly like simple sugar syrup: mix 4 parts water to 1 part sugar, boil mixture just untill the sugar dissolves, then be sure to allow the sugar mixture to cool before feeding butterflies. Adding soy sauce gives a dose of minerals and salt. Do not feed butterflies this sugar mix or honey during very cold or very dry weather as the sugar could re-crystallize inside them before being digested. Fructose is the safest bet for those times as it does not crystallize. A recipe: butterflyboutique.net. Lots of recipes here: faq.gardenweb, although I question the long term effects of the food coloring in the Gatorade that so many people have success with.
Flowers with Nectar that Butterflies Enjoy (partial list)
Aster, borage, butterfly bush, calendula, cosmos, delphinium, lilac, lupines, sweet alyssum, verbena, yarrow, zinnias. See the Pollinator Planting Guide: pollinator.org
Remember Monarch larvae only eat milkweed
Plant some milkweed in your garden, and don’t pick off the caterpillars! ‘Milkweeds and nectar sources are declining due to development and the widespread use of herbicides in croplands, pastures and roadsides. Because 90% of all milkweed/monarch habitats occur within the agricultural landscape, farm practices have the potential to strongly influence monarch populations.’ Spraying Round-Up and herbicides on roadsides reduces monarch populations. monarchwatch.org

Make A Successful Butterfly Feeder
Putting a plate inside a larger plate or saucer that is filled with water will keep ants away from the fruit. Butterflies have a good sense of smell, they have scent receptors at the ends of their antennas, and taste receptors on the bottoms of their feet. local.wgal

To attract butterflies add neon pink, red and orange plastic scrubbers to your plate or bowl. Butterflies are restricted to an all-liquid diet due to their straw-like proboscis. Photo by Leskra: panoramio.

Increase your chances of the butterflies finding their offering by having flowers close by, or paint or tape colorful flowers (real or fake) to the plate or hanging apparatus. To hang, cut three holes in a saucer, string with wire or chain and hang.
Male Butterflies need extra minerals and enjoy mud puddles. The extra sodium and amino acids are transferred to the female along with the spermatophore during mating. This nutrition enhances the survival rate of the eggs. The minerals also help in the production of pheromones which attract females. To make butterfly puddles, bury a container and then fill with sand or gravel. Fill with water, a sweet drink or stale beer.
At night and during wet weather, butterflies take shelter underneath leaves, among grass blades, or in a crevice of a rock.
How Butterflies Eat
When not in use, butterflies keep their proboscis coiled up, then unfurl it to suck up nectar, pollen, tree sap, rotting fruit, dung or other foods that are in a liquid state. asknature.
When unwound their proboscis acts as a straw. A Purple Duke extends its proboscis deep into the fruit of the Singapore Rhododendron. butterflycircle.blogspot

Due to the butterflies’ fragility to ecological change, they are an excellent indicator of an ecosystem’s health. Malachite butterflies feeding at a butterfly farm in Germany, photo by Andreas Adelmann, flickr.

Because butterflies are cold blooded, they cannot fly if their body temperature is less than 86 degrees, so keep the fruit in the sun and out of strong winds. buenavistabutterflies.
