How do you tell a butterfly from a moth? Both moths and butterflies are in the order Lepidoptera, but there are general differences that can help you know which is which.
Here are a few overall rules that can be used to distinguish moths from butterflies. Of course, there are always exceptions to the rules.
Antennae
Moths have simple thread-like or ‘feathery’ antenna without a club.
The antennae of the Polyphemus moth (Antheraea polyphemus) have hairlike olfactory receptors that are used to detect female sex pheromones.
Butterflies have a thickened club or hook on the tip of the antenna.
Antennae of the Great Southern White butterfly (Ascia monuste) have blue knobs at the end. Butterfly antennae are used for the sense of smell and balance.
Exceptions: Several families of moths have antennae with clubs, most notably the Sun moths (Castniidae).
When I saw this Wood Nymph moth (Cercyonis pegala), I had no idea what it was. It looks like bird poop, perhaps to discourage birds and other predators from eating it.
Butterflies usually have brighter colors.
The Blue Morpho (Morpho menelaus) is among the largest butterflies in the world with wings spanning from five to eight inches. Their vivid, iridescent blue coloring is a result of the microscopic scales on the backs of their wings, which reflect light.
Exceptions: Many moths are brilliantly colored, especially day-flying moths.
When we think of moths sometimes we think they are not as colorful as butterflies. The Madagascan Sunset moth (Chrysiridia rhipheus) is a day-flying moth and is considered one of the most colorful. Madagascan Sunset moths are found only in tropical forests on the island of Madagascar off the southeast coast of Africa.
Resting posture
Moths hold wings flat when resting.
The Luna moth (Actias luna) is probably the best-known of the American silk moths.
Butterflies hold wings together above their body when resting.
A Malachite butterfly (Siproeta stelenes) resting with its wings closed. The colors of the wings are a bit duller on its underside and help it to camouflage itself.
Exceptions: Many moths, including Geometrid moths (Geometridae spp.) hold their wings up in a butterfly-like fashion when resting. Butterflies in the Lycaenid subfamily Riodininae, and Skippers in the subfamily Pyrginae hold their wings flat when resting.
Pupae
Moths spin a cocoon before they pupate.
This moth used the hair from its body to create a cocoon.
Butterflies will shed their skin for the last time and reveal a chrysalis.
The Monarch caterpillar hangs in the “J” position before it sheds its skin.
Exceptions: Many moths do not spin a cocoon; many butterflies and skippers form a silken shelter, often with plant leaves.
Butterflies are diurnal and are active during the warmth of the day.
These Tiger Longwings (Heliconius hecale) are basking in the sun. The optimum body temperature for a butterfly to fly is between 82° and 102° F (28° and 39° C). They regulate their body temperature and keep it warm by practicing behavioral tactics such a shivering their wings or basking in the sun.
Exceptions: A few butterflies are active at dusk; many moth species fly during the day.
Not all moths are nocturnal. Polka Dot Wasp moths (Syntomeida epilais) fly during daylight hours.

Here it’s sipping on sap from a tree.
In this stunning image of a caiman with a vibrant crown of butterflies, the water that collects on the caiman’s skin is providing salts and minerals for several species of butterflies.
Many species of butterflies congregate on wet sand and mud to partake in “puddling,” drinking water and extracting salts and minerals from damp sand or mud. In many species, this “mud-puddling” behavior is restricted to the males, and studies have suggested that the nutrients collected may be provided as a nuptial gift during mating.

The first time I observed this behavior I was several years ago in Florida. Our family was enjoying a six-mile tubing adventure down Ichetucknee Springs near Gainesville. (The real Magic Kingdom of Florida.) As we approached the end of our trip, I noticed about fifty swallowtail butterflies of various species congregated together exactly where we needed to get out of the river.
There was a cement embankment that slid down to the river to make it easier to get out of the water. The butterflies seemed totally oblivious to us as we ascended onto the embankment. I realized that as people got out of the river, water from their bodies dripped onto the wet cement. These butterflies were sipping the salts from the sweat being washed off as people got out of the river.

Another time I experience this phenomenon was at Butterfly World in Coconut Creek, Florida. I was sitting on a bench, enjoying the many species of tropical butterflies inside the exhibit. It was a very hot day and I was covered in sweat. To my surprise, and utter delight, a Malachite butterfly (Siproeta stelenes) landed on my hand and proceeded to stick its proboscis onto my sweaty hand to sip the salt. It stayed there for several minutes, totally oblivious to my camera.
This Malachite butterfly (Siproeta stelenes) is enjoying the salt from my hand.
Recently Carol Pasternak, author of How to Raise Monarch Butterflies: A Step-by-Step Guide for Children , noticed a Silvery Blue (Glaucopsyche lygdamus) butterfly on the shoelace of her running shoes. Apparently the perspiration from her arduous workout seeped into the shoelaces providing a tasty treat for the butterfly.

Who knew that old sweaty shoes would attract so many butterflies!
Mother’s Day is just around the corner. Children will have fun making these unique butterflies for mom or grandma for Mother’s Day. And these will be gifts that will always be cherished.This cute little card made from the handprints with a little poem:
This isn’t just a butterfly, as you can plainly see. I made it with my hand, which is a part of me. It comes with lots of love, especially to say I hope you have a very Happy Mother’s Day!
When planning a butterfly garden one typically thinks of planting flowers. But did you know that trees are some of the best plants for attracting butterflies?
Three common species of trees that support dozens of butterfly species and hundreds of moth species include oaks, willows, and chokecherries. Xerces Society’s Gardening for Butterfliescalls these three trees “Keystone Trees” because attract multiple species of butterflies.
Oaks (Quercus spp.) support many different species of butterflies including the myriad hairstreak and duskywing species as well as the California Sister (Adelpha californica) and the Arizona Sister (Adelpha eulalia). Oaks also support the Imperial moth (Eacles imperiali), the Polyphemus moth (Antheraea polyphemus) and the Rosy Maple moth (Dryocampa rubicunda) in addition to others.
A Mourning Cloak (Nymphalis antiopa) is sipping on the sap of an oak tree.
There is such an incredible diversity of oak species that exist across the entire North American continent, many of which are small shrubs that can be used to add to your landscape. Some examples are the California Shrub Oak (Quercus berberidifolia), the Gambel Oak(Quercus gambelii) found in the Southwestern deserts into the Great Plains, the Turkey Oak (Quercus laevis) of the Southeast and the Scrub Oak (Quercus ilicifolia) of southeastern Canada and northeastern United States.
The Chokecherry(Prunus virginiana) is another tree that is distributed throughout much of the United States and southern Canada and is quite adaptable to various soil types and planting conditions. Chokecherry attracts widespread species of butterflies, both as a host plant for caterpillars and as a source of nectar for butterflies. Among the butterflies that use the Chokecherry as a host plant are the Lorquin Admiral (Limenitis lorquini), the Tiger Swallowtail(Papilio glaucus), the Two-tailed Swallowtail(Papilio multicaudata), the Spring Azure(Celastrina ladon) and the Coral Hairstreak (Satyrium titus).

Various willows (Salix spp.) are host plants for the Viceroy (Limenitis archippus), Mourning Cloak (Nymphalis antiopa), Red-spotted Purple (Limenitis arthemis astyanax), Tiger Swallowtail (Papilio glaucus), Mourning Cloak (Nymphalis antiopa), and the Lorquin’s Admiral (Limenitis lorquini). Willows are found in every part of the United States and Canada, with locally-appropriate native species available for any butterfly garden. These awesome trees are fast-growing and will tolerate many soil types. They come in a variety of sizes and shapes. Most willows do well in full sun and moist environments.
There are many different trees that attract butterflies, both as a source of nectar and as a host plant for caterpillars. (Click here to see a list of host trees.) Trees also provide butterflies protection during bad weather as well as a place for them to perch during the day and to roost during the night.

The vertical lines on the wings are an example of disruptive patterning. This breaks up the outline of the butterfly to make it difficult for birds and other predators to see and catch it.

This butterfly displays many interesting behaviors. It not only feeds on the nectar of flowers, the males sip nutrients from wet sand and mud and bird droppings. This behavior is called mud-puddling. From the fluids they obtain nutrients such as salts and amino acids needed for successful mating.
Banded Orange Heliconian photographed near Iguazu Falls, where the countries of Argentina, Brazil, and Paraguay meet, and one of the best places in the world to see butterflies. http://www.focusonnature.com/IguazuButterfliesList.htmIt is also common to see the male Banded Orange Heliconian sipping the salty tears of crocodiles.
Males are very territorial and will find a place to perch near the host plant, Passionvine (passiflora spp.), where they can watch for females. They patrol around the area in search of females. Once a potential mate is spotted, the male will flutter around the female in a figure-eight motion before settling beside her. If she is receptive she remains motionless, and the male then half opens his wings. He then flutters them very rapidly for a few seconds to direct his pheromones towards her antennae, which has the effect of placating her. The male then curves his abdomen around to make contact and copulate.
Just like many Heliconius species, the butterflies will find a bush or tree where they can rest for the night. They tend to find the same place every day around dusk to settle down in clusters to roost overnight.
