Distribution and habitat preferences of species of Chaoboridae in the Holarctic Region are described. Coexistence of larvae of different Chaoborus species in various water bodies reflects differences in geographical distribution, habitat preference, and phyletic relationships.

Kinematic Analysis of the Trophic Apparatus of Larval Chaoborus trivittatus (Diptera: Chaoboridae)
Annals of the Entomological Society of America, 1983The functioning of the trophic apparatus of larval Chaoborus trivittatus Loew was recorded on film for the first time and is described. The feeding response was triggered by an acoustic signal in partly immobilized 4th-instar larvae. The cycle starts with the opening of the mandibles and the mandibular fans (mean duration = 0.11 sec), followed by an ...

Response of Chaoborus (Diptera: Chaoboridae) Larvae to Different Wavelengths of Light
Annals of the Entomological Society of America, 1971Immature and mature Chaoborus larvae (Diptera: Chaboridae) were tested in a specially designed apparatus to determine their behavorial response to light of different wavelengths. Larvae were exposed to 15 wavelengths of light for 30-minute intervals. In all cases, mature larvae (3rd and 4th instars) were uniformly distributed before light exposure and ...

Differential Predation by Fish on Two Species of Chaoborus (Diptera, Chaoboridae)
Oikos, 1978Larvae of the two species Chaoborus obscuripes (V. D. Wulp) and C. flavicans (Meig.) differ with respect to shape and behaviour. These characteristics are significant for a visually dependent predator. C. obscuripes, which has more pigment (e.g. larger eyes) and the least marked diel migration pattern, may hence be more susceptible to fish predation ...
