Studies on the bioecology of Haemagogus and other wild mosquitoes are of primary medical importance because they are vectors of arboviruses such as those that cause yellow fever, dengue, and Mayaro virus disease. This study aimed to assess the vertical patterns of oviposition and temporal changes in the distribution of mosquito species in an area of the Atlantic Forest at the Ecological Reserve Guapiaçu (REGUA, Brazil). Haemagogus leucocelaenus was the most frequently captured species (73% of the specimens collected). Species richness and diversity were the highest in the samples collected from the ground-level ovitraps and decreased with height. Species composition also significantly differed between heights. Sampling month, but not measures of diversity and climatic variables, had a significant effect on species richness and diversity. Species diversity and richness decreased with height, suggesting that the conditions for mosquito breeding are more favorable closer to the ground. Species composition also showed vertical differences.
