Heatmap illustrating the distribution of mosquito species by trap type, month, and year in Harris County, Texas (2018–2022). Distribution was calculated as the number of trap sites where a mosquito species was captured per month and trap type in the (a) BG trap, (b) GV trap, and (c) CDC light trap placed in storm sewers. Each tile corresponds to a species, with months on the x-axis and study years on the y-axis. The color gradient indicates the distribution of mosquito species, with the darker blue shade indicating a broader distribution. White indicates that the species was not identified in collections. The color graduation allows for quick identification of spatial and temporal variations of mosquito species in different trap types across Harris County.
