Insect pests; Insects as carriers of disease; Medical parasitology. 2o6 Arthropods as Hosts of Pathogenic Protozoa Aedes calopus, more commonly known as Stegomyia jasciata or Stegomyia calopus (fig. 134) is a moderate sized, rather strikingly marked mosquito. The general color is dark-brown or reddish- brown, but the thorax has a conspicuous broad, silvery-white curved line on each side, with two parallel median silvery lines. Between the latter there is a slender, broken line. The whole gives a lyre- shaped pattern to the thorax. The abdomen is dark with silvery- white basal bands and silvery white spots on each side of the ab- dominal segments. Legs black with rings of pure white at the base of the segments. Size of the female to s mm.; male 3 to mm. It is pre-eminently a domesticated species, being foimd almost exclusively about the habitation of man. "Its long association with man is shown by many of its habits. It approaches stealthily from behind. It re- treats upon the slight- est alarm. The ankles and, when one is sitting at a table or desk, the underside of the hands and wrists are favorable points of attack. It attacks silently, whereas other mosquitoes have a piping or hum- ming note. The warning sound has doubtless been suppressed in the evolutionary process of its adaptation to man. It is extremely wary. It hides whenever it can, concealing itself in garments, working into the pockets, and under the lapels of coats, and crawl- ing up under the clothes to bite the legs. In houses, it will hide. 134. The yellow fever mosquito (Aedes calopus), (.\7).
