Q 01What are the four stages of a butterfly's life cycle, in order?
Egg, larva, pupa, adult
Egg, larva, pupa, adult: because the caterpillar and the winged adult look so different and eat different foods, young and adults never compete with each other for a meal.
Q 02What is the primary function of a butterfly's proboscis?
To sip liquid food
To sip liquid food: an adult butterfly has no chewing jaws, so everything it eats must be drunk through the proboscis, two long halves linked together into a tube that coils up when not in use.
Q 03What is the technical term for a fully developed adult butterfly?
Imago
Imago is Latin for 'image': naturalists saw the winged adult as the true image of its species, revealed once the larva, a word that is Latin for 'mask', had been cast off.
Q 04In chaos theory's 'butterfly effect', a butterfly flapping its wings in Brazil might set off what in Texas?
A tornado
A tornado: meteorologist Edward Lorenz posed the question in a 1972 talk, after finding that rounding off the numbers fed into his computer weather model produced a completely different forecast.
Q 05Each of a butterfly's two large eyes is a mosaic of many tiny lenses; what is this kind of eye called?
A compound eye
A compound eye gives no sharp image, but it has a wide field of view and is very good at detecting movement, so a butterfly picks out flower shapes and motion yet cannot see distant objects clearly.
Q 06How many legs does an adult butterfly typically have?
Six
Six, in three pairs, is the body plan butterflies share with every other insect, from beetles to bees, and the reason eight-legged spiders are not counted as insects at all.
Q 07Before laying eggs, a female butterfly checks that a leaf will suit her caterpillars by tasting it with which body part?
Her feet
Her feet carry taste sensors that work only on contact, so simply by landing on a leaf she can tell whether her caterpillars will be able to eat it before she lays a single egg.
Q 08To which scientific order do butterflies and moths belong?
Lepidoptera
Butterflies and moths belong to the order Lepidoptera, a name derived from Greek words meaning "scaly wings," referring to their distinctive wing scales.
Q 09Which wing markings do some butterflies flash to startle an attacking bird?
Eyespots
Eyespots look like the eyes of a larger animal: in tests, birds hesitated far longer before attacking butterflies that showed their spots than ones whose spots were covered, and some fled without attacking.
Q 10Queen Alexandra's birdwing, the world's largest butterfly, lives only in which country?
Papua New Guinea
Papua New Guinea: the giant, whose females can span more than 25 cm, survives only in scattered pockets of rainforest in Oro Province, after the 1951 eruption of nearby Mount Lamington destroyed much of its former range.
Q 11A butterfly's exoskeleton is built mainly from what material?
Chitin
Chitin gives the outer skin its toughness, but only once it has set: straight after a moult the new skin is pale and soft, and it expands before hardening within a couple of hours.
Q 12What is it called when male butterflies crowd onto damp soil or wet sand to drink?
Puddling
Puddling is mostly a male habit: the nutrients drawn from the mud are thought to be handed to the female during mating as a 'nuptial gift', which improves the survival of her eggs.
Q 13Unlike most moths, how do most butterflies hold their wings when perched?
Folded upright above the back
Q 21The painted lady's scientific name, Vanessa cardui, points to which prickly plants that its caterpillars prefer?
Thistles
Thistles: the name comes from carduus, Latin for a wild thistle, and although the caterpillars will accept hundreds of other plants, thistles are the ones they favour.
Q 22What tiny structures cover a butterfly's wings, giving them their color and patterns?
Scales
Butterfly wings are covered in thousands of tiny, overlapping scales, which are modified hairs, responsible for their vibrant colors and intricate patterns.
Q 23What primary sensory function do a butterfly's antennae perform?
Smelling
Smelling is the antennae's main job: they are covered in tiny sensors that sample the air for scents, including the chemical signals butterflies give off when courting.
Folded upright above the back is the usual butterfly pose, where most moths spread their wings flat or hold them like a tent over the body; skippers break the rule and often perch with wings half open.
Q 14Once its wings have dried, what happens to the size of an adult butterfly?
It never grows again
It never grows again: every bit of a butterfly's growing is done as a caterpillar, which outgrows and sheds its skin several times, so a small butterfly is not a young one.
Q 15Heliconius butterflies are unusual among adult butterflies for feeding on what?
Pollen
Most adult butterflies live on liquids alone, but Heliconius species collect pollen with the proboscis and digest its amino acids, which helps them live for several months instead of weeks.
Q 16What gives a Blue Morpho butterfly's wings their iridescent blue?
Structural coloration
The Blue Morpho's colour is structural coloration: the wings hold no blue pigment, and microscopic ridges on the scales reflect blue light, producing an iridescence that shifts with viewing angle.
Q 17The antennae of most butterflies differ from those of most moths by having what feature?
Clubbed tips
Clubbed tips are the quickest way to tell a butterfly, since moth antennae are usually feathery or saw-edged, though a few day-flying moths carry clubs too and one African butterfly has none.
Q 18What term describes a non-toxic butterfly evolving to resemble a toxic species to deter predators?
Batesian mimicry
Batesian mimicry, named after Henry Walter Bates who described it in Amazonian butterflies, is a harmless species copying a toxic one's warning pattern; if mimics grow too common, predators stop avoiding it.
Q 19Butterflies have four wings; which insect has only two?
Housefly
A housefly: most flying insects have four wings, but in true flies the hind pair has shrunk into tiny knobs that work like gyroscopes to keep the insect balanced in flight.
Q 20Unlike most moths, when are most butterflies active?
During the day
Most butterflies are active during the day: they are diurnal, basking in sunlight to warm their flight muscles before flying, whereas the great majority of moths fly at night.
Q 24Caterpillars spin silk from glands that open on which body part?
The lower lip
The lower lip, or labium, carries a tubular spinneret: the silk leaves it as a liquid, hardens into thread in the air, and is laid down as lines, pads and the button the caterpillar hangs from to pupate.
Q 25What happens to most of a caterpillar's body inside the pupa?
It dissolves into a soup
It dissolves into a soup: the caterpillar releases enzymes that digest its own tissues, and small clusters of cells that survive use the broth to build the wings, eyes and legs of the adult.
Q 26In classical myth, the butterfly-winged princess Psyche became the immortal wife of which god?
Cupid
Cupid, the Greek Eros, lost Psyche when she broke his trust and took her back only after trials set by his jealous mother, Venus; artists often show her with a butterfly's wings.
Q 27A butterfly's wings and legs are all attached to which section of its body?
The thorax
The thorax, the middle section, is the engine room: it carries every leg and wing and is packed with the muscles that drive them, while the abdomen behind it holds the gut and reproductive organs.
Q 28Besides colour, what do the scales on a butterfly's wings provide?
Insulation
Insulation: the overlapping scales trap a layer of air that helps the butterfly hold heat for flight; they also detach easily, which lets a butterfly slip free of a spider's web.
Q 29The painted lady, found on most continents, once had what fitting name in North America?
Cosmopolitan butterfly
Cosmopolitan butterfly suited a restless species: it lives year-round only in warm regions, so fresh migrants recolonise Europe every spring, and in some years they get as far as Iceland.
Q 30Europe's painted ladies make a round trip, spread over up to six generations, between the Arctic Circle and which continent?
Africa
Africa: no single butterfly makes the whole journey, and the autumn flight south went unnoticed for years because, as radar later showed, the insects travel on fast winds high above the ground.
