What Do Butterflies Eat?

We often get asked, “What do butterflies eat?”. . .

Butterflies eat (drink or sip) nectar through a straw-like mouth part called a proboscis  (pro-boss-kiss). Nectar is a sugar rich liquid produced by flowering plants like cosmos, verbena, zinnias, butterfly bush and yarrow.  There are thousands of flowers that butterflies can obtain nectar from.

Along with nectar, the male butterfly also needs a variety of minerals, which they acquire by sipping on ripe or rotting fruit, tree sap, piles of manure or mud.  This typical butterfly behavior is called puddling.

If you have butterflies in a cage or enclosure for more than a day, they will need to be fed.  They can be fed a variety of ripe juicy fruits, like watermelon, melons, oranges, cherries, strawberries, peaches and plums. Caged butterflies will also enjoy sipping on Gatorade and homemade nectar.   You can make your own butterfly nectar by mixing 4 parts water to 1 part granulated sugar.  Boil the mixture for a few minutes then be sure to allow the sugar mixture to cool before feeding butterflies.  Use cotton balls soaked with either the homemade nectar or Gatorade and placed on a small plate.  If the enclosure is large enough, you can also place a few potted flowering butterfly nectar plants inside to keep the butterflies happy and well fed.

To help keep male butterflies happy and enticing to female butterflies in your garden or enclosure, be sure to include a “puddling” area.  This can be done by place smooth round stones in a shallow dish along with some mud or wet soil.

If you know of a certain flower, fruit or other sweet treat that butterflies seem to love, please share your knowledge with our readers and leave us a comment below.

Enjoy the butterflies,

O’ Cassia Tree, O’ Cassia Tree…

O’ Cassia Tree, O’ Cassia Tree, how lovely are your branches…

Where some female Sulphurs are concerned, the verse above should read, how lovely are your blossoms. The brilliant yellow buds found on a blooming Cassia plant, are number one on these gals’ Christmas lists.

Christmas Cassia (Cassia bicapsularis), a vigorous, evergreen winter bloomer, decorates itself in golden blossoms of sunshine for the holiday season. It, along with several others, such as Desert Cassia (Cassia polyphylla) and Candlestick Cassia (Senna alata) serve as hosts to a variety of Sulphurs (Colias), including the Cloudless (Phoebis sennae) and several species of Oranges and Yellows.

Although female Sulphurs will place their tiny offspring upon the green foliage of the Cassia plant, they much prefer to set their eggs down upon its tender buds. Here, a newly emerged caterpillar can climb into a safe sun colored burrow which will provide him with food and shelter.

christmas butterfly blogThe lovely saffron flowers showcased by Christmas Cassias and others alike, are not only cherished by the female butterflies, but by their young as well. Sulphur caterpillars prefer to feed on Cassia’s bright petals, mimicking their yellow color while doing so.

Then, like a Christmas miracle, when the favored florets are gone and the green foliage must be consumed, Sulphur caterpillars miraculously turn a verdant hue. And, almost as if attempting a keepsake, often they retain, in the form of a yellow stripe, just a hint of the flowers they so adored.

Giant Swallowtail Butterfly vs Citrus Leafminer Moths

Giant Swallowtail Butterfly

Giant Swallowtail Butterfly

The Giant Swallowtail Butterfly (Papilio cresphontes) lay their eggs on the tender young leaves of many types of citrus, including Orange, Lemon, Grapefruit and Kumquat. The Giant Swallowtail Caterpillars feeds on the leaves of the citrus tree until pupating and emerging as one of the North America’s largest butterflies.

Damaged Citrus Leaves due to the Citrus Leafminer

Damaged Citrus Leaves due to the Citrus Leafminer

In the last several years the influx of the Citrus Leafminer has left little food for the larva of these large graceful butterflies. The Citrus Leafminer (Phyllocnistis citrella) also lays it’s egss on citrus.  The Citrus Leafminer is a very small, light colored moth. Their newly emerged larvae immediately begin feeding on the leaves and “mine” themselves inside the top or bottom layer of the citrus leaf, causing the leaves to curl and harden making them inedible for the caterpillar of the Giant Swallowtail Butterfly.

Please don’t spray citrus trees with insecticides, instead use Blue Sticky Traps or Citrus Leafminer Pheromone Traps which attract the male citrus Leafminer and help to reduce the population and reproduction of these pests.

Protect the tender new growth of your citrus tree for the Giant Swallowtail Butterfly and help create a friendlier environment for the these lovely butterflies!

Milkweed – Ensuring the Survival of Monarchs

Swamp Milkweed (Asclepias incarnata)

Swamp Milkweed (Asclepias incarnata)

Milkweed (Asclepias) is a natural wonder
- the host plant for the monarch and the queen butterflies.
Without milkweed, these butterflies would cease to exist.

Milkweed is also an important nectar source for butterflies, bees and other nectar seeking insects.

Narrowleaf Milkweed (Asclepias fascicularis)

Narrowleaf Milkweed (Asclepias fascicularis)

Milkweed gets its common name from the milky sap it secretes when you snap a leaf or break the stem. The milky substance contains cardenolides which are consumed by the feeding caterpillars and stored in the body of the adult butterfly making them toxic and bitter-tasting to potential predators.

California Milkweed (Asclepias californica)

California Milkweed (Asclepias californica)

This beautiful and important perennial belongs to the genus Asclepias.  There are over 150 species of Milkweed in the world with most of them being native to North America, South America, and southern regions of Africa.

Pictured is just a sampling of the colorful and diverse varieties of milkweed.

Butterfly Encounters offers over 20 species of milkweed seeds and provides detailed information about growing milkweed from seed.

History of The Endangered El Segundo Blue Butterfly

El Segundo Blue ButterflyIn 1927, a plane piloted by Charles Lindbergh and humorist Will Rogers landed on a dirt runway east of the El Segundo dunes.  The site was eventually chosen as the Los Angeles International Airport.

By the 1950′s a subdivision covered much of the El Segundo Blue habitat, right under the flight path of LAX airport.

In 1973, the president of the United States signed into law the Endangered Species Act (ESA), the world’s only legal prohibition against the extinction of other species, even those as small and localized as the El Segundo Blue butterfly.

In 1975, thanks to members of the conservation group, the Xerxes Society, Standard Oil Company agreed to fence off and manage their small portion of the El Segundo Blue habitat.  This was the first formal butterfly reserve in California.

In 1976, the El Segundo Blue (Euphilotes battoides allyni) was listed as protected under the Endangered Species Act.

In 1991 the Los Angeles City Council voted that two hundred acres of the dune system be permanently preserved.

El Segundo BlueThirty-three years after being classified an endangered species, the El Segundo Blue butterfly is flourishing once again on 200 acres of sand dunes near Los Angeles International Airport.

In 2009 the endangered El Segundo blue surprises scientists by rebounding and expanding its range in the South Bay.

The size of a thumbnail, the El Segundo Blue butterfly stays close to it’s host plant, Seacliff buckwheat (Eriogonum parvifolium), also called dune eriogonum or dune buckwheat.

Seacliff Buckwheat (Eriogonum parvifolium)Seacliff buckwheat is among the many buckwheat species we have in southern California.  Seacliff buckwheat is typically found on dunes and bluffs along the coastal communities from San Diego County up to Monterey County.  Like many other buckwheats, although its main blooming season is during the summer, some blooms may be observed at almost any time during the year ranging in color from a rosy pink to white and then to a deep coppery bronze when dry.

Plant some Seacliff Buckwheat in your garden today… More seacliff buckwheat would mean more El Segundo Blues!

Recipe for Sunshine…

Ever wondered how to make sunshine? Mother Nature knows how!

Below is “her” recipe for the Cloudless Sulphur Butterfly…


Start with an itsy bitsy egg. Set it on the tenderest bud of a Cassia senna plant until it turns the color of sunshine.

Then watch closely as the egg comes to life and a tiny bright caterpillar emerges.

Let the little yellow guy munch away at the Cassia senna plant for as long as he likes.

cloudless caterpillars

Notice how he grows bigger and then begins to flaunt the green hues of his host plant.

He leaves just a touch a of his sunshine showing through in his stripe.

Now spy him turn curiously into the letter J.

And magically mimic a lovely leaf.

Then Voila, Out comes the Sunshine…

Enjoy!

Wow! A Western Tiger Swallowtail egg!!!

After years of searching… I finally found a Western Tiger Swallowtail egg!

All fellow “butterfly egg hunters” out there should understand why a celebration of sorts is in order! Butterfly eggs in general can be hard to come by, especially when you are at the mercy of Mother Nature, but the Western Tiger Swallowtail’s eggs seem to be particularly, well, quite literally, out of reach.

Sycamores, Willows and Cottonwoods, the Western Tiger Swallowtail’s ( Papilio rutulus ) host plants, are not only typically abundant in source, but also grow large in structure. This makes the prospect of obtainng a Western Tiger’s egg nothing short of finding a needle in a very, very big haystack.

Desperate Times Call For Desperate Measures!

Western Tiger Swallowtails are common in the rural areas of Southern California. Often they can be seen fluttering high near the canopies of their favorite host plants, especially native  California Sycamores ( Platanus racemosa ). Other than reverting to my childhood days of tree dwelling, I can think of no other way to seek out and acquire a Tiger Swallowtail’s egg. Once, while driving, I noticed a Sycamore that had recently been struck down and was laying along the roadside. Admittedly, crazily, I pulled over my car and looked over the trees foliage for eggs, but, much to my disappointment, found none.

I don’t know if  Lady Luck decided to have a chat with Mother Nature or not, but for whatever reason, last week she finally resolved to shine upon me. My good friend and fellow confessed “butterfly egg hunter” actually spied a Western Tiger female laying eggs near her home. Next thing I knew the ladder was in my car and then I was high up in branches of several lush Sycamore trees searching the leaves for eggs.

Like many butterflies, I sought to camouflage myself by wearing earthy hued colors, such as green and brown. I also kept an over-sized hat on, hoping no one would recognize me and might instead mistake me for some over zealous gardener. I searched in the canopies for sometime, then just as I was about to fold up my wobbly ladder and go home I found what I had been hunting for.

Wow!!!… Finally, a Western Tiger Swallowtail egg!!!! It was just sitting there topside, upon a sizable leaf, perfectly disguised amongst the spotted patterns typical of the Sycamore. I had always thought that female butterflies preferred to lay their eggs on the soft new growth of their host plant, but not in this case.

Here, mama clearly opted for the covert over cushy and also, possibly due to her size, choose to lay the egg at the base of a considerable leaf which could sustain her body weight. Whatever the circumstances, I was glad to have found the egg! I am hoping to watch the caterpillar which emerges from it go through full metamorphosis, but am most looking forward to seeing it fly off as a lovely swallowtail butterfly into the canopies from which it came. -K.D’Angelo
