Species can be attracted to, or disoriented by, sources of artificial light through positive phototaxis
(Verheijen 1985; Longcore and Rich 2004).
max] 480 nm) stimulate positive phototaxis
and longer wavelengths inhibit [phototaxis].
However, a common misunderstanding is that this attraction represents a positive phototaxis
Based on the premise that in the absence of moonlight, sandflies would exhibit positive phototaxis
and be attracted to light traps, a maximum catch would be expected during a new moon.
, manifest as an increase in OD, was observed for wavelengths between 440 nm and 538 nm with a maximum phototactic response at 503 nm.
A study by Yasuda (1995) suggests that females are attracted to flush, while males might tend to settle on flush through positive phototaxis
and/or negative geotaxis.
