  abstract = {1. {A}nopheline larvae are surface feeders and allocate most of their time to search for food at the water surface. {H}owever, species of the {A}nopheles gambiae {G}iles complex may also show bottom feeding. {T}he consequences of this foraging tactic for life history are unknown, yet may be relevant to understand inter-specific competition patterns. 2. {T}he diving ability and activity of larvae of the main {A}frican malaria vectors, {A}n. coluzzii and {A}n. gambiae, at two different water depths (14 and 30cm) were assessed. {W}e further explored the biological relevance of diving for food harvesting by monitoring key life history traits in two species treatments (single or mixed species) and two food treatments (surface or bottom feeding). 3. {O}verall, {A}n. coluzzii larvae showed more diving activity than {A}n. gambiae. {W}hen feeding at the bottom both species, and especially {A}n. gambiae, showed a delayed emergence and a reduced emergence rate. {M}oreover, {A}n. gambiae also suffered a reduced wing length. 4. {M}ixed-species rearing had a detrimental effect on the life history traits of {A}n. gambiae but not on {A}n. coluzzii, suggesting a competitive advantage for the latter in our experimental conditions. 5. {T}he present results confirm that anopheline larvae are able to forage for food at the bottom of their breeding site and that {A}n. coluzzii shows a superior diving activity than {A}n. gambiae and this at a lower cost. {T}hese behavioural differences probably reflect specific adaptations to different aquatic habitats, and may be important in shaping species distributions and the population biology of these important vector mosquitoes.},
