Diptera


[R] Order of holometabolous insects; larva apodous; head well-defined in the Nematocera (Tipulidae, also called daddy-long legs, mosquitoes, etc.), small and inconspicuous in the Cyclorrhapha: larva called maggot ; pupa of Cyclorrapha remains enclosed in the last larval skin, which forms the puparium; adult bears one pair of membranous wings, the hind wings being modified into halteres; mouthparts of adults adapted for sucking (in this case forming a proboscis) and sometimes for piercing.
Principal pest families: the Tipulidae and the Cecidomyiidae; the Agromyzidae, the Anthomyiidae, the Lonchaeidae, the Tephritidae, the Psilidae, the Chloropidae, the Muscidae and the Tachinidae. Beneficial insects are also included, particularly in the Tachinidae, along with numerous enemies of Man and domestic animals.
