Butterfly (pronounced buht-er-flahy)
(1) Any of numerous diurnal insects of the order
Lepidoptera, characterized by clubbed antennae, a slender body, and large,
broad, often conspicuously marked wings which are typically closed when the
creature is at rest (the adjectival form is lepidopteran).
(2) A person who moves effortlessly from one social
situation to another, usually as “social butterfly”.
(3) Someone perceived as unserious and (originally)
dressed gaudily; someone flighty and unreliable; a bolter (common between the
seventeenth & nineteenth centuries; now archaic).
(4) In competitive swimming, a racing breaststroke, using
a dolphin kick, in which the swimmer brings both arms out of the water in
forward, circular motions.
(5) In carpentry, as butterfly joint (or wedge), a type
of joint or inlay used permanently to hold together two or more pieces of timber,
either as something aesthetic (usually with a contrasting color of timber) or
merely functional (also known as the bow tie, dovetail key, Dutchman joint, or
Nakashima joint).
(6) In sculpture, an X-shaped support attached to an
armature.
(7) As butterfly arm, the swinging brackets of a
butterfly table.
(8) In film editing, a screen of scrim, gauze, or similar

expiry dates, on a stock exchange or commodity market; historically a
combination of four options of the same type at three strike prices giving
limited profit and limited risk.
(11) In medical & surgical dressings, a prepared
bandage or the use of surgical tape, cut into thin strips and placed across an

architecture, stained glass, visual art and industrial design.
Pre 1000: From the Middle English buterflie, butturflye & boterflye,
from the Old English butorflēoge,
buttorflēoge & buterflēoge. It was cognate with the Dutch botervlieg
and the German Butterfliege
(butterfly). The construct was (with
variations was butere (butter) + fly. Etymologists
note alternative origins for the name.
Either (1) it was first applied to creatures with wings of a notably
yellowish hue (perhaps the dominant or single species of the type in an area)
or (2) as a response to the belief that butterflies ate milk and butter or (3) the first element may have originally been butor- (beater), a mutation of bēatan (to beat), a reference to the
movement of the wings. The idea of the fragile things as thieves of milk and
butter is supported by similar instances in other European languages including
the German Molkendieb
(butterfly (literally “whey thief”) and the Low German Botterlicker (butterfly (literally butter-licker) & Bottervögel (butterfly (literally
“butter-fowl”). There was also the notion
they excreted a butter-like substance, memorably expressed in the Dutch boterschijte (butterfly (literally “butter-shitter”). Most memorable however is the explanation in
the tales of the Brothers Grimm (die
Brüder Grimm, Jacob (1785–1863) and Wilhelm (1786–1859)) in which witches
disguised themselves as butterflies. The
early forms in Middle English superseded the non-native Middle English papilion (butterfly) borrowed from the Old
French. Butterfly is a noun &
adjective, butterflied is a verb & adjective and butterflying is a verb. The noun plural is butterflies.

Butter was from the Middle English buter & butter, from the
Old English butere, from the
Proto-West Germanic buterā, from the Latin
būtȳrum, from the Ancient Greek
βούτῡρον (boútūron)
(cow cheese), the construct being βοῦς (boûs) (ox,
cow) + τῡρός (tūrós) (cheese). Fly was
from the Middle English flye & flie, from the Old English flȳġe & fleoge (a fly,
a winged insect), from the Proto-Germanic fleugǭ (a fly) & fleugon (flying insect), from the primitive Indo-European plewk- (to fly). It was
cognate with the Scots flee, the Saterland
Frisian Fljooge, the German Low
German Fleeg, the Danish flue, Norwegian Bokmål flue
& Norwegian Nynorsk fluge, the Swedish
fluga and the Icelandic fluga, the Old Saxon fleiga, the Old Norse fluga, the Middle Dutch vlieghe, the Dutch vlieg, the Old High German flioga
and the German Fliege (fly (literally
"the flying (insect))). The Old
English fleogende (flying) was from
the primitive Indo-European root pleu-
(to flow).

Butterfly
was applied first to people circa 1600, originally in reference to vain and
gaudy attire, an allusion to the butterfly’s colors. By 1806 it had become a class-based put-down referencing
a transformation from a lowers social class to something better, invoking the
idea of progression from sluggish caterpillar to graceful butterfly
(essentially a synonym for bounder). The
reference to flitting tendencies (from one interest, occupation etc) dates from
1873 and the social butterfly (one who moves effortlessly between social
encounters and events) emerged in the 1920s.
The swimming stroke was first defined in 1935. As a general descriptor (butterfly agave, butterfly
ballot, butterfly fish, butterfly flower, butterfly plant, butterfly bomb,
butterfly keyboard, butterfly chair, butterfly ray, butterfly shell et al),
it’s applied wherever the resemblance to the open wings appears compelling.
Native to the forests of Central and South America, the Blue Morpho is one of the world’s largest butterflies. The wings are bright blue with lacy black edges, the result of light reflecting off microscopic scales on the back of their wings. Lovely though the blue appears, it’s often not seen because the underside of this butterfly’s wing is a dull brown which provides a camouflage against predators. When the wings are closed as the Blue Morpho sits on a tree, it blends in well.

Butterfly valves came into use in the late 1700s and have
been popular since for their ease of manufacture, simplicity of operation and
low maintenance. The butterfly nut
appeared in 1869 although in some markets it usually called the wing nut;
interestingly, the similar fastener with a male thread is known as a wing screw
or wing bolt but apparently never a butterfly screw or bolt, presumably because
the delicate butterfly is thought emblematically female. The phrase “Who breaks a butterfly upon a wheel?” is from Alexander Pope's (1688-1744)
Epistle to Dr Arbuthnot" (1735). The allusion is to "breaking on the
wheel", a form of torture in which victims had their long bones broken by
an iron bar while tied to a Catherine wheel, the idea a critique of excessive
effort or deployment of resources to solve a simple problem; the less
confronting phrase “sledgehammer to crack
a nut” means the same thing. The
phrase “butterflies in the stomach” is a descriptive reference to the mild stomach
spasms induced by anxiety and dates from 1908.
The butterfly effect is the most celebrated idea from (the somewhat
misleadingly named) chaos theory, introduced in the 1972 paper Predictability: Does the Flap of a
Butterfly's Wings in Brazil Set Off a Tornado in Texas? by US academic
meteorologist Edward Lorenz (1917–2008).
Lorenz had developed the theory based on his observations in the early
1960s (in one of the earliest big-data models) that a tiny change in one
variable (one of a dozen numbers representing atmospheric conditions) had an
extraordinary effect upon long-term outcomes.

The use of the butterfly motif in industrial design in
1967 became a footnote in legal history in the trial of the boxers Rubin
"Hurricane" Carter (1937–2014) & John Artis (1946-2021 for a
triple murder committed at the Lafayette Bar and Grill in Paterson, New Jersey. Evidence presented by the prosecution claimed
that witness descriptions of the getaway car matched the hired car Carter was
found driving in the vicinity of the Lafayette immediately after the killings,
their statements even including a mention of the distinctive butterfly-shaped
taillight chrome. However, although a
witness said the rear lights lit up across the back of the getaway car, the
taillights on Carter's Dodge Polara, although there was certainly a butterfly
chrome surround, lit up only at the edges; it was the more expensive Dodge Monaco which had the extended lights. In the ever changing swirl of model names and
trim levels which characterized the US industry during its golden age (1955-1973),
in 1966 the Polara was Dodge’s entry-level full-size model, above which sat the
higher-priced Polara 500, Monaco, and Monaco 500. For some reason (and this was not unusual),
the lineup’s nomenclature in Canada differed, being Polara, Polara 440, Polara 880, and
Monaco. In both markets however, it was
only the Monaco which featured the extended tail lamps.

second or two, that may have not been significant because tests did reveal the
reflective silver finish on the Polara’s rear panel did indeed appear red at
certain angles when the brake lights were activated but the distinction, along
with a witness’s correction of this in the 1976 re-trial did lead some to suggest
the police might have been coaching witnesses; “hardening the statement” in law enforcement lingo. That actually aligned with the evidence
provided by another witness and the prosecution would later suggest later
suggested the confusion was caused by the defense misreading the court
transcript.

Butterfly doors are used on some high-performance cars
and not wholly as a gimmick, the advantage being that in such usually low-slung
vehicle, they do make entry and exit somewhat easier that scissor doors. There’s even more functionally on certain
competition cars because (1) they allow the carefully-crafted aerodynamics of the canopy to be preserved, (2) the driver can enter and leave the cockpit
more quickly and (3) the design allows the structural integrity of the shell to
be maximized. Butterfly doors open
upwards and outwards and in that they differ from scissor doors which are
hinged to move only upwards, thus offering the possibility of a greater
aperture while demanding more lateral clearance. Exotic doors were seen in a handful of pre-war cars, none
of which reached production, but it was the Mercedes-Benz 300SL (W194) race-car
of 1952 which brought to public attention the idea car doors could be something
different. Such was the response that
the factory used the gull-wing doors when, in 1954, the 300SL (W198) was offered
in a road-going version although the engineering, like the concept, was not
new, having before been used in both marine architecture and aircraft
fuselages. Similarly, the design elements
which underlie butterfly and scissor doors can be found in buildings and
machinery dating back in some cases centuries but of late, all have come most
to be associated with exotic cars.
1967 Alfa Romeo 33 Stradale
Variations on the theme had appeared on the show circuit for
some time before butterfly doors debuted on the Alfa Romeo 33 Stradale in 1967
which was much admired but it was thought the complexity of such things would
limit their use to low volume runs such as the Stradale (of which only 18 were
built) or one-off styling exercises such as the Alfa Romeo Carabo (1968) which
used scissors. However, scissor doors
appeared on the prototype Lamborghini Countach (LP500) and, despite the doubts
of some, were retained when the production version was released in 1974. Since then, gull-wings (which open upward on
a horizontal axis, hinged from the roof), scissors (which open upwards, rotating
on a horizontal axis, hinged from the front), butterflies (which open upwards
and outwards on an axis unaligned to the vertical or horizontal, hinged from the
A (windscreen) pillar and dihedrals (scissors which move laterally while
rotating ) have become common (relatively speaking) and designers seem intent
on adding some new twist which seem sometimes to add no advantage but usually
attract publicity (admittedly an advantage in the abstract), the most complex
to date being the dihedral synchro helix doors which open forward,
slide forward and rotate up.

When Mercedes-Benz released the SLR McLaren (2003-2009), in
an attempt to make explicit the link with the 300SL, they laid it on with a
trowel, the phrase “gullwing doors” appearing in the factory’s original press
release no less than seven times, just in case people didn’t get the
message. Nobody was fooled and they’ve
always been called butterflies. One
clever piece of engineering was seen when the SLR roadster was released, those butterfly
doors made possible by using hinge points along the rather than at the top. McLaren used a variation of this idea when it released the McLaren MP4-12C (2011-2014), omitting the top hinge which allowed the use of frameless windows even on the roadster (spider).
IBM's ThinkPad 701 series was available during 1995 and
was that year's biggest seller in its class, its distinctive feature the "butterfly"
keyboard, a design in response to the obviously contradictory demands that
laptops be smaller and lighter while still equipped with keyboards big enough
comfortably to be used (especially with the big, clumsy fingers of men). The 701 was marketed in what was then an
untypically IBM manner, newspaper advertisements in the run-up to the launch published
with nothing but a butterfly in the corner, the IBM logo later added while a
few days before the debut, the text "Watch
for the announcement" appeared.
Butterfly had actually been the project's internal codename although it
had never been intended for use as a product, apparently because IBM's
corporate policies didn't permit the use of the names of living. Still, the use in the teaser advertisements
did suggest they planned it to catch on as a nickname and doubtlessly hoped for
a better outcome than the last time a codename was picked-up, the unfortunate
"peanut" (the PCjr (1984-1985)) not fondly remembered.
The 701 series, some models even offering a dual-boot
into OS/2 Warp (3.0), was well-received and the butterfly keyboard much
admired. The main body of the keyboard
was a two-piece construction, which, gear-driven by the movement of the lid, spread
apart to become a single unit as the laptop was opened, the process reversed as
the lid closed. IBM actually called it
the TrackWrite, but it was universally known as the butterfly and so compelling
was the design that to this day, one is on permanent display in Manhattan's
Museum of Modern Art (MoMA). Popular
though it was, the market moved and the place on the demand curve at a price
point which interested IBM was for laptops with larger screens so the need for
the butterfly technology vanished, the 701 remaining unique. Some patents have recently been filed which
suggest manufacturers may be planning to release another laptop with a butterfly
keyboard but, in an age of ultra-thin devices, it will presumably be a thing of
low-tactility and thus lacking the responsiveness which had been one of the
most attractive features of the original.
