Examples of Anopheles larval habitats that were missed by the drone mapping process but recorded by field operatives within the SIS arm. A: Small (< 3 m) breeding site on a track underneath dense forest canopy; B: Small (< 1 m wide) breeding site obscured by a structure; C: Medium (~ 5 m wide) breeding site within a stream channel obscured by riparian tree canopy
