permanent swamps. It is not strictly a local form, a migration of 10 

 to 12 miles being quite possible. For the past few years, the sylvestris 

 has been the prevailing species in the northern part of the state. It is 

 especially troublesome to the gardener. 



The Woodland-Pool Mosquito 



The Aedes stimulans (formerly called subcantans) resembles 

 closely the big brown salt-marsh mosquito of which we have previously 

 spoken (see page 6), and is easily mistaken for it. There is a 

 white band at the base of each tarsal segment and a white band at 

 the base of each abdominal segment. This mosquito also winters in 

 the egg stage and produces a large brood early in the spring. It is 

 not considered migratory and does not trouble man greatly except 

 as he builds nearby, or otherwise penetrates its haunts. The stimu- 

 lans is often a nuisance to camping parties and has caused the listing 

 of mnsquito netting as a necessary part of a camper's outfit 



The House Mosquito Group 



In the house mosquito group we will consider two of the five im- 

 portant members, the Culex pipiens and the Anopheles quadrvmacu- 

 latus. 



Dr | R. Smith, the pioneer of mosquito work in New Jersey, 



characterizes the house mosquito as fol- 

 lows : "It is of medium size, deep yel- 

 lowish to dark brown in color, the legs 

 and beak are not banded, and the ab- 

 domen has a narrow whitish band at 

 the base of each segment. It is rath- 

 er a slight species and not especially 

 hairy, having indeed, 'a lean and hungry 

 look.' " The Culex pipiens passes the 

 winter as an adult female hiding away 

 in cellars, buildings and other protected 

 places. When warm weather comes in 

 the spring, she sallies forth and layj 

 her eggs, which go through the trans- 

 formations outlined above.

 A Most Unwelcome Guest 



The house mosquito is found every- 

 where about human habitations. It 

 breeds in large numbers! wherever 

 water stands long enough); in rain- 

 barrels, water tubs, tin cans, broken 

 bottles, cellar excavations, even a 

 broken bit of crdckery. It breeds in 

 abundance in foul, polluted water, cess- 

 pool overflows, house sink drains, etc. 

 The man who designed the typical city corner sewer catch basin be- 

 friended the mosquito, for he provided a place where dirty, stagnant 

 water lies for weeks and unless these basins are oiled, they produce 

 mosquitoes in untold numbers.
