Diptera (dip'te-ra), . pi. [NL., neut. pi. of 
dipterus, two-winged: see dipterous.} 1. An or- 
der of metabolous hexapod insects. They are two- 
winged insects, or flies, with two membranous wings with 
radiating nervures, not folded at rest, a posterior pah* be- 
ing only represented by halteres or poisers ; no mandibles 
as such, but a suctorial proboscis instead, formed of modi- 
fled mandibles, maxilla), and the central labiuin, here 
called glossarium ; usually two maxillary but no labial 
palpi ; antennfe generally short ; two large compound eyes, 
often of thousands of facets, and three ocelli or simple eyes ; 
and the prothorax and metathorax reduced, the niesotho- 
rax being correspondingly developed. Metamorphosis is 
complete ; the larvae are apodal, or with only rudimentary 
feet ; the pupie are usually courctate (see cut under coarc- 
tote), sometimes obtected. The common house-fly, blue- 
bottle, etc. , are characteristic examples. The power which 
many of these insects have of walking on smooth surfaces 
with back downward is due to the construction of the feet, 
which act as suckers. They have, besides the ordinary two 
claws, several little cushions called pulvllli, beset with fine 
hairs expanded at their tips into a kind of disk ; the adhe- 
sion is aided in some cases by a viscid secretion of these 
hairs. The order is a very large one : there are said to be 
9,000 European species alone, supposed to be not a twenti- 
eth part of the whole number. Aoout 4,000 are described as 
North American. A few are useful scavengers, but many 
are injurious insects, and some are great pesU. Gnats, 
mosquitos, gad-flies, blow-flies, bot-flies, tzetzes, etc., be- 
long to this order. It Is variously subdivided, one divi- 
sion being Into four suborders : the Pupipara, which are 
parasitic, and developed in the body of the parent, as the 
bee-lice ; the Brachycera, or ordinary flies ; the Hmoccra, 
or crane-flies, gnats, midges, mosquitos, etc. ; and the wing- 
less Aphaniptera, or fleas, which are oftener ranked as a

distinct order. Another division is into the suborders Or- 
thorhapha and Cyclorhapha, according to the character of 
the metamorphosis : the former with two sections, AVf/in- 
tocera and Brachycera; the latter with also two sections, 
Aachim and Schizophora.
