LONG-HORNED DIPTERA (NEMATOCERA) The crane-flies (Tipulidae) are easily recognized by their long, slender bodies, narrow wings, and exceed- ingly long, fragile legs, which characteristics have given them the name 'granddaddy-long-legs," a name more correctly ap- plied to the harvestmen, which are round-bodied spiders with very long legs. The maggots of crane-flies, sometimes called leather- jackets, or meadow-mag- gots, are dirty white, with a tough skin, and feed upon the roots of plants, decaying vegetable matter, and fungi. They are fre- quently found in the decay- ing wood and mold in the crotch of an old tree or in a stump, while several species wrhich feed on their roots sometimes become abundant enough to do considerable damage to grasses and grains. The adults are among our largest flies, the common species. FIG. 348. Life history of a mosquito (Culex sp.).
