FLY 
Fly, FLov/sr. A fmall, but very beautiful Fly, 
dcfcribed by Clufius. The general colour is black; 
the eyes are white; on the back are feven yellow 
fpots; and the two v,?ings have a filvery appear- 
ance. 
Flvj Grey, or Trumpet-Fly. This is a 
pretty large fpecies: the body is of a dufliy grey 
colour, approaching to black; the breaft is bcfet 
with a great nuinber of long yellow hairs; die 
wings are large and tranfparent; the figure of the 
body is oblong; and the eyes are large and black. 
The female depofits her eggs in the noftrils of 
flieep, deer, and fome other animals. It is called 
the Trumpet-Fly from a peculiar noife it makes 
during the heat of fummer; but Linn.xus gives it 
the name of oeflrus, and reters it to the Gad-Fly 
eenus. 
Fly, Hornet. This fpecies is as large as the 
common Piornet; and fo nearly refembles it, that 
an incurious obferver cannot djftinguifn the differ- 
ence. The head is large; the fnout, which is long 
and black, has a fharp point; and the eyes are pro- 
minent'. The breafc is large, bunched, and of a 
duflcy colour ; but the wings, legs, and belly, are 
an iron grey; and the upper part of the body, 
which confifts of f>;ven joints, is black and yel- 
low. 
Fly, Hornet, Virginian. This infeft is 
equal in fize to our largeft Flies: the head and 
eyes are black, with a v/hite line running from 
the Ihoulders to the mouth ; and the mouth itfelf is 
armed with a long and ftrong weapon. The fhould- 
ers are of a blackilli brown colour; and it has 
two filver wing's. At the back part there are fe- 
ven or eight joints of a whitifn colour; but the other 
parts, except the belly, which is cl a yeiiov/ifli afh- 
colour, incline to black. 
Fly, FIornet, Muscovy. This fpecies lias a 
very long body; and large oblong eyes, which oc- 
cupy the greatefc part ot the head. The fnout is 
black, hardifh, and divided into three parts; and 
with it the infe6t can penetrate cloth, or other fub- 
llances of a fimilar confiftence. LinnjEus gives 
the general appellation of afilus to Flies of this 
kind; of which he enumerates four ibrts, viz. the 
rapacious afilus ; the hairy afilus; the afilus with 
round wincrs; and the afilus which ftin2;s the le2;s 
through the ftockings. 
Fly, Horse, Common. The body of this in- 
feft is pretty large, and of an oblong fliape rounded 
at the extremity; the flvin is fmootli; the eyes are 
large; tlie wings are tranfparent; and the colour 
is greyiili. Each of the legs is armed with four 
fhort fharp claws; and the fnout is ciavated, of a 
cylindrical fliape, and blunt at the extremity. 
Fly, Horse, Great. This fpecies has a grey- 
ilh head; large black eyes; and broad tranfparent 
duflcy coloured wings marked with iron-grey lines. 
The breaiJl" and body are grey, except that a trian- 
gular white fpot extends quite down the back; 
the thighs are black; and the legs are yellow. 
Fly, Horse, East Indian. The bite of this 
molt pernicious infeft is very fevere. It is about 
two inches long, nearly the fame in breadth, and of 
a brown colour, with a yellow ftreak along the 
body. This Fly builds it's ncfc with great care in 
the rafters of buildings, where it depofits it's eggs, 
and hatches it's young. It feeds on fruit; and, 
when killed, has a mofc difao-reeable fmell. 
Fly, Hop.se, Chinese, The body and under- 
wings of this Fly are of a fnining green colour, 
which has tlie brilliance of poliflied metal; the tips 
FLY 
of the wings and the under-fide are dufky; but the 
upper wings, which are of a light brown hue, are 
very thin and tranfparent. 
Fly, Horse, Purple and Brown. This fpe- 
cies is a native of the Well Indies. It's wings are of 
a dull purplifli brown colour variegated with fome 
tranfparent fpots. Linnjeus gives thefe Flies the 
name of hippobofca. 
Fly, Ichneumon, Common. This infed" has 
a long, (lender, black body; the head, bread, and 
feelers, are of the fame colour; the legs are red- 
difn, long, and flender; and the wings are tranfpa- 
rent, except that there is a black fpot near each of 
their edges. A weapon projefts from the tail, 
longer than the whole body, confifting of three fili- 
form rays, the middlemoft of which is red, and 
the two exterior ones black. Ray gives this Fly 
the appellation of the ¥/afp Ichneumon, with a 
flender, longifh body, and three very long bridles 
at the tail. 
Fly, Ichneumon, with Silver-Coloured 
Wings. This fpecies has an oblong body, of a 
black colour, with two black feelers. The wines 
are marked near their upper edges v/Ith blackifli 
Ipots; the legs are rcddilhi; and from tlie tail pro- 
ceed three long hairs. This infeil, which very 
nearly refem.bles the former, has four wings like ail 
the reft of the genus. 
Fly, Ichneumon, Vv'^hitish. This fpecies is 
entirely white, except four black fpots on the 
wings, which the infe6t, when fitting, keepr cre6l. 
It has fix feet, two globous prominent bl.x-k eyes, 
and two fnort black feelers. The body is flen- 
der, round, and upwards of half an inch long; 
there are three brifdes at the tail, of equal lengths 
v/ith the body, which, in the a6l of flying, the crea- 
ture fpreads into a triangular figure. This Fly 
makes it's appearance in May and June. 
Fly, St. Mark. Thefe Flies generally make 
their appearance about St. Mark's dav, when they 
are feen in prodigious numbers. They are fome- 
what fmaller than the large blue Flcfli-Flies, and 
have neither trunks nor teeth ; but, notwithftanding 
this feem.ingly innocent organization, they ai e very 
mifchievous, particularly in gardens. They are 
found about fruit-trees, fitting on the leaves, and 
on the flower-buds, Vv'hich they eflentially injure^ 
by fucking the juices of thofe tender parts, and 
either deftroying them, before they expand thcm- 
lifives, or i-endering them veiy weak. 
Some writers gravely tell us, that thefe Flies 
were originally provided with flings ; but that, be- 
ing found extremely noxious, St. Mark deprived 
them of thefe oftenfive weapons throughout all ge- 
nerations. Ridiculous as this flory may appear, it 
is firmly believed in many Roman Catholic coun- 
tries, efpeciaily among the vulgar. The mouth 
of the St. Mark's Fly is of the fame mechanifin 
with tliat of the tipula, being compofed of tv/o 
membranous lateral lips, like the two valves cf 
a fhell-fifli, which defend and cover tv/o internal 
fiefhy lips. 
Hie male may be eafily diftinguifhed from the 
female by having a much larger head, and reticu- 
lar eyes v/hich in a manner cover the whole head. 
The wings of this Fly are fomewhat longer than 
the body, and crofl^ed in fuch a m^anner as that one 
of them entirely covers the other. 
The peculiarities attending thefe Flies, when 
they quit the w^orm date to enter into that of the 
chryfalis or nymph, are worthy of obfervation.
