CRANE FLY is a common name referring to any member of the insect family TIPULIDAE, of the order Diptera , true flies in the superfamily Tipuloidea . Cylindrotominae , Limoniinae , and Pediciinae have been ranked as subfamilies of Tipulidae by most authors, though occasionally elevated to family rank. In the most recent classifications, only Pediciidae is now ranked as a separate family, due to considerations of paraphyly . In colloquial speech, crane flies are sometimes known as DADDY LONGLEGS, a term also used to describe opiliones or the family Pholcidae , both of which are arachnids, or "MOSQUITO HAWKS". The larvae of crane flies are known commonly as leatherjackets.

Crane flies are found worldwide , though individual species usually have limited ranges. They are most diverse in the tropics , and are also common in northern latitudes and high elevations.

The Tipulidae is one of the largest groups of flies, including over 15,000 species and subspecies in 525 genera and subgenera. Most crane flies were described by the entomologist Charles Paul Alexander , a fly specialist, in over 1000 research publications .

The head of a Tipula sp.


The adult crane fly, resembling an oversized mosquito , has a slender body and stilt-like legs that are deciduous , easily coming off the body. The wingspan is generally about 1.0 to 6.5 cm. The antennae have up to 39 segments. It is also characterized by a V-shaped suture on the back of the thorax and by its wing venation. The rostrum is long; in some species it is as long as the head and thorax together.


For terms see Morphology of Diptera

Tipulidae are large to medium-sized flies (7–35 mm) with elongated legs, wings, and abdomen. Their colour is yellow, brown or grey. Ocelli are absent. The rostrum (a snout) is short to very short with a beak-like point called the nasus (rarely absent). The apical segment of the maxillary palpi is flagelliform and much longer than the subapical segment. The antennae have 13 segments (exceptionally 14–19). These are whorled, serrate, or ctenidial. There is a distinct V-shaped suture between the mesonotal prescutum and scutum (near the level of the wing bases). The wings are monochromatic, longitudinally striped or marbled. In females the wings are sometimes rudimentary. The sub-costal vein (Sc) joins through Sc2 with the radial vein, Sc1 is at most a short stump. There are four, rarely (when R2 is reduced) three branches of the radial vein merging into the alar margin. The discoidal wing cell is usually present. The wing has two anal veins. Sternite 9 of the male genitalia has, with few exceptions, two pairs of appendages. Sometimes appendages are also present on sternite 8. The female ovipositor has sclerotized valves and the cerci have a smooth or dentate lower margin. The valves are sometimes modified into thick bristles or short teeth.


Tipulinae *


The larva is elongated, usually cylindrical. The posterior two-thirds of the head capsule is enclosed or retracted within the prothoracic segment. The larva is metapneustic (with only one pair of spiracles, these on the anal segment of the abdomen), but often with vestigial lateral spiracles (rarely apneustic). The head capsule is sclerotized anteriorly and deeply incised ventrally and often dorsolaterally. The mandibles are opposed and move in the horizontal or oblique plane. The abdominal segments have transverse creeping welts. The terminal segments of the abdomen are glabrous, often partially sclerotized and bearing posterior spiracles. The spiracular disc is usually surrounded by lobe-like projections and anal papillae or lobes.

The adult female usually contains mature eggs as she emerges from her pupa , and often mates immediately if a male is available. Males also search for females by walking or flying. Copulation takes a few minutes to hours and may be accomplished in flight. Adults have a lifespan of 10 to 15 days. The female immediately oviposits , usually in wet soil or mats of algae . Some lay eggs on the surface of a water body or in dry soils, and some reportedly simply drop them in flight. Most crane fly eggs are black in color. They often have a filament, which may help anchor the egg in wet or aquatic environments.

larvae (leatherjackets) have been observed in many habitat types on dry land and in water, including marine , brackish , and fresh water . They are cylindrical in shape, but taper toward the front end, and the head capsule is often retracted into the thorax. The abdomen may be smooth, lined with hairs, or studded with projections or welt-like spots. Projections may occur around the spiracles . Larvae may eat algae, microflora, and living or decomposing plant matter, including wood. Some are predatory.

Larval habitats include all kinds of freshwater, semiaquatic environments. Some Tipulinae, including Dolichopeza Curtis, are found in moist to wet cushions of mosses or liverworts. Ctenophora Meigen species are found in decaying wood or sodden logs. Nephrotoma Meigen and Tipula Linnaeus larvae are found in dry soils of pasturelands, lawns, and steppe. Tipulidae larvae are also found in rich organic earth and mud, in wet spots in woods where the humus is saturated, in leaf litter or mud, decaying plant materials, or fruits in various stages of putrefaction.

Larvae can be important in the soil ecosystem, because they process organic material and increase microbial activity. Larvae and adults are also valuable prey items for many animals, including insects, spiders , fish , amphibians , birds , and mammals .

The larvae of some species consume other living aquatic insects and invertebrates, which could potentially include mosquito larvae. Many adults, however, have such short lifespans that they do not eat at all.

Despite widely held beliefs that adult crane flies (or "mosquito hawks") prey on mosquito populations, the adult crane fly is anatomically incapable of killing or consuming other insects.


The common European crane fly, Tipula paludosa , and the marsh crane fly, T. oleracea , are agricultural pests in Europe. Crane fly
Crane fly
larvae of economic importance live in the top layers of soil where they feed on the roots, root hairs, crown, and, sometimes the leaves of crops, stunting their growth or killing the plants. They are pests on a variety of commodities. Since the late 1900s, T. paludosa and T. oleracea have become invasive in the United States. The larvae have been observed on many crops, including vegetables, fruits, cereals, pasture, lawn grasses, and ornamental plants .

In 1935, Lord\'s Cricket Ground in London was among venues affected by leatherjackets. Several thousand were collected by ground staff and burned, because they caused bald patches on the wicket and the pitch took unaccustomed spin for much of the season.
