Prospecting effort associated with larval mosquito inventories on Mayotte during the 2008–2012 surveys.
In total, 420 habitats yielded mosquito collections and in certain cases, theseare in close proximity and overlap as a single point on the map.

Occurrence on Mayotte during the 2008–2012 surveys of the 27 principal mosquito species when present in more than 20% of at least one type of larval habitat.
Figure 4.
Correspondence analysis for the 18 main types of larval habitats vs. the 27 principally collected mosquito species.
Represented here are axis 1 (horizontal) and axis 3 (vertical) that explained 33.3% (22.9%+11.4%) of total variance; the scales are equal for the two graphs (grid step size = 1). The separation along axis 1 follows a temporal gradient from non-permanent (axils of banana-pineapple, taro and Typhonodorum plants) to permanent habitats (marsh and swamp water, water pools during the rainy season and slow flowing water). Axis 3 displays another gradient from habitats with restricted openings (crab-holes, tree-holes) to habitats with open access (mushroom caps, fallen leaf litter and snail shells).

Diagrammatic representation of the known distribution of the 44 mosquito species occurring on Mayotte.
Four species are considered as endemic to Mayotte and three others endemic to the greater Comoros Archipelago. Most species occur on Madagascar and the African continent, and of biogeographic interest, 10 are shared with Madagascar and one with the African continent. Culex sp. A is not listed as its specific identification needs further documentation (see Text S1). Species are listed in alphabetic order.
