How do butterflies breathe? Smell? Taste?
Adult butterflies, as well as caterpillars, breathe through a series of tiny openings along the sides of their bodies, called "spiracles." From each spiracle, a tube called a "trachea" carries oxygen into the body. Butterflies don't have noses and lungs as we do. Butterflies "smell" with their antennae. Many butterflies can taste with their feet to find out whether the leaf they sit on is good to lay eggs.
What kinds of butterflies and moths live in my neighborhood?
We've put together a world atlas to help you find butterflies in any locality. In the USA, we have butterflies and moths listed by state. In the United Kingdom, by postal code. We also have lists sorted by continent, country, and some localities.

Do butterfly hibernation boxes (butterfly houses) work?
If you intend them as an attractive garden decoration, they work
superbly. If you'd like to provide shelter to butterflies, these
two articles say they most likely will not use them. However, several
of our visitors have been successful.
How long do butterflies live?
Opler and Krizek discuss this difficult question in Butterflies East of the Great Plains, where they state that the expected life span, which is usually much shorter than the maximum life span (because of weather, predators, and many other factors), ranges from about 2 to 14 days. Maximum life span ranges from about 4 days for the Spring Azure to 10 to 11 months for the Mourning Cloak. Just as with people, females generally live longer than males. Butterflies which hibernate or go into reproductive diapause also tend to live longer.
How can I tell a moth from a butterfly?
Butterflies and moths both belong to a group of insects called "lepidoptera", meaning that they have wings covered with scales. They are related in many ways. Butterflies are generally brightly-colored while moths are generally drab, though they are many dramatic exceptions to this. Almost all butterflies are active during the day, and most (but by no means all) moths are active at night. A good way to tell the difference is by their antennae. Butterfly antennae are shaped somewhat like a golf club, with a long shaft. Most moths have either simple filaments tapering to a point, or complicated affairs with many cross-filaments.
How many kinds of butterfly are there?
Worldwide, there are approximately 28,000 species. There are about 725 species in the USA and Canada. About 2,000 species have been found in Mexico. About 80% of all species are in the tropics. The United Kingdom has 58 species of butterfly and 2,000 species of moth.
Where do butterflies go at night?
At night or during bad weather, butterflies will usually hang from the undersides of leaves, or crawl into crevices between rocks or other objects, and sleep.
What do butterfies eat?
Adult butterflies sip nectar from flowers through their tongues, which act like straws. A very few butterflies do not visit flowers, but instead feed on tree sap or rotting organic material.
You can feed butterflies with a butterfly feeder and homemade nectar. For more info, click here.
What do caterpillars eat?
Almost all caterpillars eat plant materials. Most eat leaves, but some eat seeds, seed pods, or flowers. The caterpillar of the Harvester butterfly eats aphids.
My school wants to build a butterfly garden but we need donations. Where should we look?

What are the largest and smallest butterflies?
Queen Alexandra's Birdwing (Ornithoptera alexandrae), with a wing span of 11-1/8 inches (280 mm), is found only in the rain forest of New Guinea. Destruction of its habitat is threatening this beautiful creature with extinction.
The smallest butterfly, the Pygmy Blue (Brephidium exilis), is found in the southern United States. Its wingspan is 1/2 inch (15 mm).
What are the world's rarest and most common butterflies?
Queen Alexandra's Birdwing (Ornithoptera alexandrae), is found only in the rain forest of New Guinea. It is the rarest and biggest of all butterflies. Destruction of its habitat is threatening this beautiful creature with extinction.
The most common butterfly is the Cabbage White.
Are there more moth species of butterfly species?
Moth species outnumber butterfly species by 16-to-1.
Which state has the most butterfly species?
Arizona, with 220.
How do butterflies communicate?
Butterflies communicate mostly through chemical signals. Males produce 'pheromones' to attract females. A few species communicate with sound. For example, the male Cracker Butterfly can produce noises with its wings.
What makes their wings colorful?
Butterfly wings are covered with scales (that's the meaning of the word 'lepidoptera'). Each scale is a single color, most of which are produced by pigments. The iridescence that's sometimes seen is produced from a reflective microstructure on the surface of the scales.
What colors can butterflies see?
Butterflies can see red, green, and yellow.
What is a caterpillar?
Most insects have a larval stage known as a 'grub', with six legs. Butterfly and moth grubs have up to ten extra legs, called 'prolegs.' Since these extra legs cause them to look and act differently, these grubs are called 'caterpillars.' Some caterpillars turn into butterflies, but most turn into moths.
What are 'prolegs'?
Caterpillars have the 6 legs of other insects, plus up to ten 'prolegs' that distinguish them as the grubs of moths or butterflies. The 6 true legs are jointed, with a little claw on the end of each. Prologs are cylindrical, not jointed, with a tiny hook that makes them good for walking or clinging. The 6 true legs on the thorax remain throughout pupation, and these become the legs of the adult butterfly or moth. The prolegs disappear.
How do caterpillars see?
Most have six simple eyes, called 'ocelli' or 'stemmata.' Some species have fewer than six.
How do caterpillars breathe?
There is an oval opening called a 'spiracle' on each side of each segment. These are connected to a tube, the 'trachea.' As the caterpillar moves, air is pumped into the trachea, causing oxygen to be taken in and carbon dioxide to be pushed out. Caterpillars do not actually breathe as we do, but air is exhanged by the compression and extension of each segment.
How do caterpillars hear?
It's not really known if caterpillars can hear. They make no noise other than chewing.
Is frantic wriggling normal behavior?
Yes, it is their response to feeling threatened.
What does it mean when a caterpillar arches the front of its body and remains motionless?
Caterpillars go through several stages, called 'instars', in which they change their skin. To break through the old skin, which they've outgrown, some caterpillars arch their backs.
