Abstract
<jats:p><jats:bold>Abstract </jats:bold> The timing of host‐seeking behaviour was studied in two mosquito species, <jats:italic>Anopheles annulipes sensu lato</jats:italic> and <jats:italic>Coquillettidia linealis</jats:italic> at Mundic Creek, near the Upper River Murray in South Australia. Hourly sampling using carbon dioxide‐baited traps revealed consistent patterns in the timing of host‐seeking. <jats:italic>Coquillettidia linealis</jats:italic> displayed a very large peak in host‐seeking activity at sunset, followed by a much reduced level throughout the night and a smaller peak at sunrise. <jats:italic>Anopheles annulipes</jats:italic> s.l. differed by displaying a significantly smaller peak at sunset, followed by higher amount of activity throughout the night compared with <jats:italic>Cq. linealis</jats:italic>. The two taxa, while both crepuscular and nocturnal, spread their host‐seeking effort out differently throughout the night, indicating that they have different resource requirements.</jats:p>
