Immature Stages of Chaoborus borealis Cook (Diptera: Culicidae)
Published online by Cambridge University Press: 31 May 2012
Extract
The immature stages and adults of Chaoborus borealis Cook were collected near Churchill, Manitoba, in 1949 and 1950 in investigations on the natural control of biting flies (James, 1953; James and Smith, 1958). Cook (1956) described the adult and the fourth-instar larva in his revision of the Nearctic Chaoborinae, and noted the similarity between the fourth-instar larva and that of C. flavicans (Mg.). This paper contains descriptions of the egg, the first-, second-, and fourth-instar larvae, and the pupa of C. borealis.
